Talk:Silencer (firearms)

New Section: Effect on bullet velocity?
There seem to be a section missing on how a Suppressor/Silencer affect bullet velocity. It's a common misconception that putting a suppressor on a gun will always yield less accuracy and less bullet velocity, when in fact the opposite is true in many cases. Modern suppressors have no direct contact with the bullet and their design actually increase bullet velocity. Unfortunately I can't find any real good references that elaborate on the circumstances and when it increase the velocity and when it doesn't for this, which is why I put this here instead of directly in the page.

Here are a few youtube videos about the effect on bullet velocity with a mounted suppressor: https://www.youtube.com/watch?v=LeWL3EL1ymM https://www.youtube.com/watch?v=LWK2jHG5XfE

Section 'Sources of firearm noise'
Unfortunately, this section is needlessly complicated and unclear (i.e.: discussing irrelevant items, use of incorrect terms, etc.). These paragraphs were obviously written by someone unacquainted with the principles of firearm suppression that are widely accepted by the industry. Cleaning it up a bit to aid comprehension.108.181.1.84 (talk) 22:53, 7 August 2013 (UTC)

Other issues
The vocabulary used throughout much of the article is either confusing or misleading, and in some cases just doesn't make any sense (looks like some of it was translated using google). Article could be significantly reduced to facilitate understanding by removing items that are discussed repeatedly and/or are contradictory.108.181.1.84 (talk) 07:58, 8 August 2013 (UTC)
 * It needs work, thanks for taking the initiative. Just be careful when deleting text that you do not wipe out any references, particularly named ones, as other sections may be relying on the information and they get hosed up as a result.--Mike - Μολὼν λαβέ 10:04, 8 August 2013 (UTC)

Hi Mike, thanks for the advice, although I'm not sure I get what you are saying. There were only two citations in the second paragraph of the intro, neither of which are named. I could not see any issue arising out of the removal of those lines either.108.181.1.84 (talk) 11:07, 8 August 2013 (UTC)
 * It may have been a previous editor, I rolled it back a bit to be safe.--Mike - Μολὼν λαβέ 23:43, 8 August 2013 (UTC)

Ok sounds good. I still think we should remove this second paragraph from the introduction, it really serves no purpose and the origin of the word silencer is discussed a few lines further (not to mention that reference3 is using a single, completely irrelevant article to imply 'widespread use' which is not only incorrect but improper use of the citation system). Second sentence is discussed in Sources of firearm noise section. Finally, the legal terminology in the last sentence is just clutter. regards108.181.1.84 (talk) 15:41, 10 August 2013 (UTC)

The lede needs work, but I don't think I would trim it yet. The lede (or intro) is supposed to summarize the article. So information in the lede will appear redundant at times. This isn't like a magazine article or book chapter. The lede is a quick summary that pops up in search results, on phones, etc. Probably after the article is improved we can rework it to make it more accurate and coherent.--Mike - Μολὼν λαβέ 15:51, 10 August 2013 (UTC)

I find the first paragraph does that very well for now. The second isn't redundant, it's just confusing and unnecessary. It summarises the article, yes, but not accurately. I think it's the first step in bringing this article up to B standard; we can systematically work the article and then come back to the introduction because it's going to change again for sure. 'Legalities of suppressors' in the US is only briefly discussed in one paragraph of a part of section 4 and this issue in and of itself is going to become an article as soon as someone decides to put the time into it (and there's going to be an article for the legals of suppressors in every country eventually) so there's really no point in putting this in an article that is clearly more technical in nature. I also think we can only do this one step at a time, and by the looks of it it's going to take quite a bit of time. Honestly, the article is a disaster, and there's no reason for it to be because there is plenty of information about this. 108.181.1.84 (talk) 16:40, 10 August 2013 (UTC)


 * I agree with you completely. Do what you need to do, ping me if you need help with sources or formatting, but it seems like you have a good handle on it. Time's getting scarce for me again. Some advice, though, if you mention a brand name...some dirtbag socialist with only 2 nickels in his pocket will call it advertising. Mention the NFA laws in the US outside of 1 paragraph and people from countries where you need a license to see a picture of a firearm in a magazine will call it US-centric. If you say how nobody has ever been killed with a legally owned suppressor or mention that they are actually a safety device to protect hearing, the same types will accuse you of POV pushing. :) Just kidding, but not really.--Mike - Μολὼν λαβέ 16:53, 10 August 2013 (UTC)

Awesome, glad we could agree. I'll be looking forward to your comments. I have no military background, but a lot of professional experience with firearms. I'll keep your advice in mind throughout the process here. Thanks again. regards108.181.1.84 (talk) 17:09, 10 August 2013 (UTC)

Progress
Progress --- the opposite of Congress.

But seriously, why is this section even in this article?

I say, remove it. ---98.245.171.233 (talk) 20:36, 29 May 2015 (UTC)

Progressivism is a general political philosophy based on the idea of progress that asserts that advances in science, technology, economic development, and social organization, can improve the human condition. This is exactly what decriminalisation and legalisation of suppressors is about. — Preceding unsigned comment added by 108.181.1.84 (talk) 03:21, 18 August 2013 (UTC)
 * I think of "progressivism as the new fascism", but think it is perfect for this article.--Mike - Μολὼν λαβέ 04:00, 18 August 2013 (UTC)


 * I don't deny that the perception of 'progress' today does not entirely concord with it's definition and in many ways I feel the same 108.181.1.84 and Mike. In reality however, progress is not an ideology, but seems to have become one of late. And much like democracy, if they were not skewed by politicians, lobbyists and others trying to market ideas and opinions, progress would be about improving the quality of life of all individuals. Not for a 'greater collective good', but for the personal well-being, at the individual level, of each person making up the society in question. Criminalising protective equipment over half-a-handful of people who might choose to use it for nefarious, and unintended purposes, is certainly not progress, regardless of how it may be defined.
 * I'm not advocating that every firearm be equipped with theses devices, nor do I think that this is the intent in being progressive. But at the very least allow and individual the liberty of choosing to make use of if the intent is to reduce harm. I think everyone will agree that in North America (USA, as well as Canada) we possess values like freedom and integrity, and in such a society hindering the will of individuals to protect themselves from work and sport related hazards is certainly not progress.


 * Basically it boils down to: hearing is important and protecting your hearing is the right thing to do because if you lose it you can't get it back. Being aware of this reality that, why would anyone (especially the government, who should be looking out for us) want to make it illegal for anyone else to protect themselves from hearing damage, especially if it is going to cost society millions of dollars? Is providing health care workers with jobs, health insurance and hearing aid companies with revenue by harming the general population considered progress?? I think progress is something that every individual does for themselves, it's not something others can do for you because the only person who knows what is good for you is yourself: not a politician who came to shake your hand around election time or a psychologist who sees you a couple hours a month. But ultimately progress, much like science and spirituality, is variable and it evolves. As we become more and more aware of our environment and the universe and how it functions, we learn new ways of doing things and improving how we can enjoy and appreciate everything life has to offer to us for as long as our bodies will allow it.


 * Based on this interpretation, I used the term 'progress' with the simple intent to indicate that, as in any other such situation: a few people\institutions decided to give it a try and got the ball rolling for the others who were uncertain about it. It seems to have demonstrated significant benefits in pretty much all instances with very few drawbacks, if any at all.


 * I'd like to hear what everyone has to say about this so we can make an informed decision on whether or not this is the correct term to use in this instance. It is my belief that this is the correct one but there may be better that I haven't considered. regards108.181.1.84 (talk) 16:47, 18 August 2013 (UTC)


 * The correct term to use is whatever has verifiable citation to corroborate its usage. I noticed that without actually providing a citation. Referring to vaguely-defined "educated individuals, knowledgeable about firearms and law" is insufficient, because that falls under weasel words, which greatly undermines this article. This talk page is not citation, and your discussion with one other person is not a reference. I'd undo your edit, except it seems, which I'm sure you'll insist on restoring at some point later.


 * The definition of "progressive" nor its appropriateness is not at issue here (not on my part anyway). The lack of supporting material is the problem. If you don't intend to improve the article with verifiable references, you should abstain from removing citation request tags. I'm not even asking that the phrase be deleted; I'm asking for detail on that point of view.


 * I'm not going to get into an edit war over this. If you restore the opinionated phrase, I will restore the citation request. If you then remove that citation request, I will solicit admin intervention, because this article is quickly falling into editorializing via contentious labels, and Wikipedia is not a soapbox. — Samatict (talk) 04:58, 6 September 2013 (UTC)

Can somebody explain why this section and the comments in it are on the talk page for this article? I don't see any connection with the topic and I think the section should be removed. ---Dagme (talk) 20:31, 27 June 2014 (UTC)

Sound suppressors and heat retention
Something that isn't really covered in this article is how sound suppressors, by virtue of slowing down a fired cartridge's hot propellant gases, allow those same gases to heat up the suppressor and the attached firearm more quickly than it would had the gases been allowed to simply leave the muzzle unsuppressed. You can see a number of youtube vids showing guns with suppressors being shot while being recorded on infrared cameras, or how suppressed guns at firing ranges get hot enough to boil water poured on them after a bit of firing. Even the article here on the old Sten mentions how the suppressed versions overheated very quickly.

The question is, how much faster do suppressors increase the rate at which a suppressor-equipped firearm heats up? Does the increase depend on the design? Do integral suppressors heat up faster due to how they bleed off more propellant gas than non-integral ones do? --Mazryonh (talk) 06:13, 11 February 2014 (UTC)


 * Good questions. Doesn't answer all of them, but the following source is illuminating: http://emptormaven.com/2007/03/freebore-boost-effects/
 * Based on physics we can say that in theory, holding efficiency roughly constant between designs, the heating rate decreases with suppressor volume and increases with propellant mass. Radiation rates would be a second-order effect, but suppressors for heavier firing rates or cartridges are often run with "cozies" to prevent heat mirage during shooting, so that they can hardly radiate at all until the operator pauses and takes off the insulator to let them cool.Dbooksta (talk) 04:47, 4 March 2014 (UTC)

Attachment
I would appreciate more detail on the section on "Attachment".

Some years ago, at a time when there was no information at all on attachment in the article, I made a similar request. Now there is rudimentary information but the topic is still very mysterious. The article says that

"most suppressors have a "female" threaded end, which attaches to "male" threads cut into the exterior of the barrel"

and that this applies in particular to handguns. But this cannot be a simple matter. On a semi-automatic pistol, the barrel is in most cases completely enclosed within the slide, so a major modification of both barrel and slide would be necessary to have the silencer attach by means of external threads. On most modern revolvers, the front sight and possibly the extractor shroud extension make the shape of the front part of the barrel far from round. So again in this case, the modification would have to be quite drastic.

A detailed explanation of attachment methods would greatly improve the article. ---Dagme (talk) 21:38, 27 June 2014 (UTC)


 * Revolvers as a rule cannot be suppressed due to the cylinder. A few purpose built revolvers have been built to be suppressed but it is not the norm, so the front sight is not even an issue. On most pistols, a longer barrel with threads that extend beyond the slide are used. On rifles you have two basic methods: threaded and direct-connect. The threaded versions work like the previously mentioned pistol, screw the can onto the threads. Direct-connect attaches over an existing barrel device such as a flash suppressor or muzzle brake. There are either threads or grooves on these devices that allow quick attachment and detachment like the AAC Blackouts and SEI Vortex. A huge problem is source material. NFA items receive a fraction of the coverage that they need in the mainstream gun press, so the bulk of material is found on company websites, forums, blogs, etc. The socialists and hoplophobes are quick to tear that sort of material down.--Mike - Μολὼν λαβέ 23:25, 27 June 2014 (UTC)

Pending/failed legislation
Since when do we mention proposed or failed legislation? If the law passes then of course we'd mention it. But if we add every proposed law to related articles then there'd be an overwhelming amount fairly useless material in articles. I note that the congressman is about to retire, and the the bill isn't even notable enough to mention in his biography. Unless someone has a good reason for including it, I'll delete it (again). Felsic2 (talk) 18:30, 17 September 2016 (UTC)
 * In October 2015, Arizona Congressman Matt Salmon introduced the Hearing Protection Act to remove suppressors from the NFA.

Amazon.com has a searchable version of this book. Searching it doesn't bring up any instances of "counter" or "mail" or any relevant mention of "Norway". The citation to this book and "Volume 1" have been tagged with "page number" requests for 18 months. Furthermore, the citation to some material was added nine years after the material itself was added. So I'm calling "bullshit". Unless someone can verify the citations to this source, I'm deleting it.
 * Legal regulation of suppressors varies widely around the world. In some nations, such as Finland, Norway and France, some or all types of suppressor are essentially unregulated and may be bought "over the counter" in retail stores or by mail-order.

 * Personally, I think it should be removed, but one of your cohorts made a hobby out of creating full blown articles about proposed legislation. In fact one or two are still kicking, but that promotes your bias, so you are probably ok with it and I don't see you raising a stink over those. I have the print version and if I find the time, I will get the page numbers. From my recollection, countries may not be listed individually, just that certain countries have politicians that recognize these as safety devices as opposed to people in the US who want to see the hearing of shooters permanently damaged.

unsourced content in regulation
The following is unsourced; moving here, per WP:PRESERVE


 * Europe
 * In Austria, the purchase or possession of a suppressor is prohibited according to §17 of the Austrian Weapons Law.
 * In the Czech Republic suppressors are, according to §4 of Weapons and Ammunition Law, considered an A-class weapon, which means a special exception is needed to possess them. This makes suppressors illegal for any practical purpose.
 * In Germany suppressors are handled in the same way as firearms; if a firearm requires a specific permit, the corresponding suppressor requires the identical permit as well. For example, suppressors for freely available airguns are also freely available. Suppressors are currently not specified exactly by means of a certain minimum attenuating level in dB which separates them from improved flash hiders or advanced muzzle brakes. Firearm suppressors require a "legal need" to own them, just like the firearms they are designed for.
 * In Hungary, the purchase or possession of a suppressor is prohibited for civilians.
 * In Italy the purchase or possession of a suppressor is prohibited except for military personnel (Law 110/75 Art. 2).
 * In the Netherlands suppressors are only legal if used for airguns. All other civilian use and ownership is prohibited by law.
 * In Norway, suppressors are not regulated.
 * (alt) In Norway the sale of suppressors is not regulated in any way. And anyone can buy one over the counter. Some distributors take it upon themselves to check that the buyer has a Firearms Licence for a suitable weapon.
 * In Poland, suppressors are not classified as "important weapon parts". Therefore, they are completely legal in all calibers, requiring no registration or permit. However the Polish Firearms and Ammunition Act (art.10, p. 5) states that firearms ownership approval cannot be issued for firearms equipped with silencer or adapted to be used with silencer.
 * In Romania, the purchase or possession of suppressors is illegal for civilians. Only military and law enforcement personnel are authorized to use them.
 * In the Russian Federation, ...(left sourced content) The law lacks any straight definition of what a "device for noiseless shooting" is, or what decibel level is considered to be "noiseless", therefore it is completely up to the expert investigating the device whether it would be considered a "device for noiseless shooting" or not. That concerns not only specifically designed sound suppressors, but such devices as muzzle brakes, compensators and flash suppressors.
 * In Turkey, civilian purchase, sale or possession of suppressors are strictly prohibited, with possible jail terms of up to 25 years if convicted. Suppressors can only be purchased by military personnel when approved by the officer in charge of the base armory. Individual law enforcement officers are not eligible to purchase or possess suppressors unless these are issued by a local agency, in which case these would be registered to the General Directorate of Security in Ankara.
 * In Ukraine, suppressors are legal and not regulated.


 * North America
 * In Canada, ... (left sourced content) special licensing is required for businesses to import and sell suppressors, and they are typically only available to law enforcement, conservation agencies, and the military.


 * Oceania
 * In Australia, suppressors are prohibited for civilians unless authorised under a commissioner's permit.
 * New Zealand has no restrictions on the manufacture, sale, possession, or use of suppressors.

This reduces or eliminates attention drawn to the shooter (hence the Finnish expression: "A suppressor does not make a marksman silent, but it does make him invisible").

The section on OSS use of the High Standard is incorrect.
The OSS used a custom made High Standard in two calibers, .22 Short and .32 ACP. The .22 short version could not be heard to fire from 15 feet away. The guns had 12" barrels the last 6" of which were drilled and a silencer was built around them with baffles and I believe filled with steel wool. .22 Long Rifle is supersonic and would NOT be used in a 12" barrel unless special sub sonic ammunition were used.

These guns are currently stored in a building on Route 32 in Ft. Meade across the street (approximately) from the NSA Cryptography museum. A former CIA agent pointed that out to me. Many of the specials weapons from WWII are stored there.

This is my understanding from conversations I have had with veterans who were there.Digitallymade (talk) 14:00, 6 February 2017 (UTC)

Inaccuracy i the Firearm Noise Anatomy
This statement: ''Muzzle blast generated by discharge is directly proportional to the amount of propellent contained within the cartridge. Therefore, the greater the case capacity the larger muzzle blast and consequently a more efficient or larger system is required.''

Is incomplete. Muzzle blast is a direct result of the pressure of expansion gases as they exit the muzzle. This is affected by the operating pressure of the cartridge, the speed of burning of the powder, and the length of the barrel. For example... from the same barrel .22 Short or .22 CB or .22 BB produce very little explosive noise when that barrel is over 18" long. .22 Long Rifle High Velocity produces substantial and hearing threatening noise in the SAME gun.  I've used .22 Short to shoot in my basement from a rifle.  In a semi-automatic rifle the short rounds will not self extract which is no problem for gallery shooting. Digitallymade (talk) 14:12, 6 February 2017 (UTC)

What is this supposed to mean?
from this page:

Alan C. Paulson, a renowned firearms specialist, claimed to have encountered an integrally suppressed .22 LR that had such a quiet report,[14] although this is somewhat uncommon." 

I've known people who used the OSS guns. They cannot be heard (in .22 Short) at a distance of 15 feet.

Properly evaluating the sound generated by a firearm can only be done using a decibel meter in conjunction with a frequency spectrum analyser during live tests.

I've never heard of anyone using a frequency analyser to test a silencer. And I don't think it is necessary. A local gun range, (Freedom Arsenal) has designed and engineered their own suppressors. There .22 rimfire silencer has the best rating for sound suppression on the market.Digitallymade (talk) 14:18, 6 February 2017 (UTC)
 * You're probably right, about this and the other two sections. Remember that we should only add material that's verifiable in published sources. Felsic2 (talk) 16:03, 6 February 2017 (UTC)


 * .22 S is not .22 LR.
 * Frequency analyzers are described in professional silencer literature, and frequency shifting is part of several patents. It's described in secondary sources such as Paulson's books, cited here.  Georgewilliamherbert (talk) 20:58, 6 February 2017 (UTC)

Suppressor → Silencer (firearms) – Suppressor is very obviously a neologism that was almost unheard of in this context until a very recent public information campaign by the NRA and various trade groups that began in only 2011. The WP:COMMONNAME policy requires that article titles reflect that silencer is, and has been, the common name since the device was invented in 1902. Silencer is also the correct legal term, and was the correct technical term until the US gun industry decided to change it for public relations purposes. The silencer industry trade group the American Suppressor Association didn't think to get on board with the new term until 2014; before that they were the American Silencer Association, what with the word silencer being in the name of many of the trade group's member companies and the name of most of their products. You'd think the people who make the things would know the "technically correct" name of their own product, but they changed because a public relations memo got passed around. The Wikipedia argument for why suppressor is more "correct" is that silencers do not eliminate 100% of noise, but that is not how English works. The UK English term for muffler is silencer, with no regard for the obvious fact that car silencers/mufflers do not make cars "silent". Worse, any dictionary can confirm that "suppress" does not imply any lesser degree of silence than silencer, or muffler for that matter. The verbs silence, suppress or muffle all mean to quieten, curtail, or reduce, without necessarily requiring that the object is curtailed 100%. The point of this name game is not to create any more or less technical accuracy in terminology, but only to manipulate public emotions and feelings.Arguably, the NRA name game has created a counter movement among gun rights activists, making use of silencer no more neutral than suppressor. The fact is, however, that Wikipedia follows a common name policy. This is why we have Anti-abortion movements and pro-life is a redirect, even if activists on one side feel slighted by the words.

 * Oppose - "Silencer" is the euphemism, used in movies/TV which depict a device which does not actually exist. Real guns are really loud, they can't be "silenced", but they can be "suppressed" - and the industry term is "suppressor". This move would communicate poor knowledge to the public and perpetuate a myth. Perhaps we should develop a "silencer" article as a place to document the fictional gun attachment found in movies and TV?  Even if you were to argue that "silencer" has a slight liead onc commonality, WP:NATURALDIS suggests Using an alternative name that the subject is also commonly called in English reliable sources, albeit not as commonly as the preferred-but-ambiguous title as a way to avoid using a parenthetical disambiguation. -- Netoholic @  12:03, 25 February 2018 (UTC)
 * Silence and suppress mean the same thing. See any dictionary. It’s like saying erasers don’t exist because they leave smudges behind. It’s why we distinguish between a vacuum and a perfect vacuum. The idea that silencer was made up by movies and TV is contradicted by all the sources. It’s true that media depictions are inaccurate, but if we had to change the name of everything that movies get wrong we’d have to start by renaming sex. Dennis Bratland (talk) —17:14, 25 February 2018 (UTC)
 * Silence deals only in sound. This device also suppresses the visible flash of firing. That's why "silencer" is a wholly inaccurate (or at least incomplete) euphamism. Wikipedia is an encyclopedia and part of that is to provide reliable and accurate knowledge. Moving this article perpetuates the fiction over the fact. -- Netoholic @  08:18, 26 February 2018 (UTC)
 * I didn't want to waste space listing dictionary content, but here goes:

The OED says the verb silence means "1.a. trans. To cause or compel (one) to cease speaking on a particular occasion; also, to overcome in argument." Overcoming in argument does not only deal with sound. "b. To cause (an animal or thing) to cease from giving out its natural sound; to still, quieten." Does not mean to make absolutely quiet; only quieter. " c. To stop, suppress (a noise or sound)" Literally defined as meaning suppress. It adds " put down, repress", and in battle, to compel enemy guns to stop firing, not to literally make them inaudible Ninjas. The American Heritage Dictionary agrees the words are literally synonyms: "To curtail the expression of; suppress: silencing all criticism; silenced their opponents." Merriam-Webster says silence (v) is "forbearance from speech or noise". Forbear means choosing not to, it doesn't mean becoming Ninja or ghost quiet. Webster also says "absence of mention" in the sense of "oblivion, obscurity, secrecy". MacMillain says "1 to stop someone or something from speaking or making a sound, 2 to prevent someone from giving an opinion or from criticizing you 3 very informal to kill someone so that they cannot give information to an enemy or someone in authority". Dictionary.com (Random House + Collins) says "1 to put or bring to silence; still. 2. to put (doubts, fears, etc.) to rest; quiet. 3. Military. to still (enemy guns), as by more effective fire." Doubts and fears do not only dieal with sound.This is why we say "absolute silence" when that is what we mean; mere silence is like merely "cleaning". We don't use tortured definitions of eraser, or disinfectant or street cleaner this way; hundreds of English words would have to change it we followed this kind of logic.I have a very long list of evidence that the gun industry and gun media never thought silencer was wrong until 2011-2014. Before that, they always used the words interchangeably with no mention of silencer being wrong. Prior to the mid-90s, they never used suppressor to mean silencer; they only referred to flash suppressors with that word. Even post-2010, they only explicitly said that silencer is inaccurate if they were writing an advocacy or op-ed piece against legal restrictions of silencers. I even have one example of a product review in which they say the silencer works exactly like you see in Hollywood movies, quote "phut-phut" unquote, making the gun's discharge quieter than the bullet hitting the backstop.Keep in mind how suppress is defined at the OED " 1. trans. To overcome or keep down by force or authority. a. To reduce (a person, a community, corporate body, etc.) to impotence or inactivity; to deprive of position or power; to keep in a state of subjection." impotence or inactivity sound pretty absolute. " b. To overcome (a person or group) by force; to overpower, vanquish, subdue." When you vanquish or overpower something, it is done fighting; you have won entirely. If your country is invaded and you vanquish the invaders, you're not being invaded any more, not even a little bit. " 1.c. To withhold or withdraw, d. To cause (a practice, action, etc.) to cease; to put an end to; to prevent or disallow the use of; to stop, discontinue. Also: to put down (a rebellion, uprising, or the like) by force; 2 (trans) a. To banish or keep hidden". Banishment is absolute. Stop means stop. If you suppress the noise of gunfire, this says you're stopping the noise. "Putting an end to" the noise. Other dictionaries say the same things: "to stop" "top put an end to" "to keep secret". Note that something is either secret or it isn't. If it gets out, it's not secret. The AHT adds "curtail" and "prohibit". If you choose -- if you choose to read these definitions this way, then suppressor is just as inaccurate as silencer for the same reasons. Suppress can be read, if you so choose, as meaning absolutely putting down, preventing, or putting and end to. But as I said, English doesn't work that way. — Berean Hunter   (talk)  15:12, 27 February 2018 (UTC) — Berean Hunter   (talk)  21:49, 27 February 2018 (UTC) — Berean Hunter   (talk)  23:02, 27 February 2018 (UTC)

 * My response is indeed a valid point, Dennis. I'm correctly pointing to the documentation for ownership and you cited "Silencer is also the correct legal term" in your initial post without qualifying it with a citation. That official documentation is directly relevant to the argument that you made. I cited it in my support statement below.
 * Maybe DYEL wasn't sufficiently explained. Any editor can discuss whether a fact is verifiable or not without it being relevant who or what they are or what their personal experiences are. Implying an editor lacks experience to comment is WP:OWNBEHAVIOR. Are they even American? Why would anybody outside the US have any idea whats on a US form? Anyway, I probably shouldn't have even brought up the legal term, which is cited in the article already. The US legal term was first established in the National Firearms Act of 1934. If we were having trouble deciding which of two names was the common name, then maybe the legal name, or the name the inventor chose, or whatever, could be a tiebreaker but in this case silencer is hands down the only common name, no contest it wins by a mile. Not just in reliable mainstream sources, which alone would be sufficient, but in any sources, whether highbrow books and news media, or lowbrow newsblogs, and, ironically, even in gun-enthusiast media and the silencer manufactures. So it was overkill to have mentioned it when the common name question is so decisive. And this article isn't only about the US, so saying it's "the" legal term is misleading, when it's only what the term in the legal code in the US. I don't know what word all the other counties use is, though (not that it matters) I bet it's silencer. --Dennis Bratland (talk) 22:11, 27 February 2018 (UTC)
 * That you make so many personal assumptions about me is amusing, but the real story here is how you think article names should be based upon what one particular government's form says.

My rationale below is "COMMONNAME and the fact..." so please don't try to put words in my mouth. I made one assumption about you that I stand by. You haven't tried to discuss verifiablility; you haven't provided sources. The burden is on you to back up your assertions. If what you say is true then it shouldn't be that hard to back it up.

Discussion
Besides the fact that the common name policy requires using silencer even if it is "wrong" or not "technically" or "scientifically" correct, the fact is that suppressor is not the gun industry's standard term, and only very recently have some, but only some, in the gun industry agreed to insist on the word suppressor. One gets the sense that they realize its just propaganda.Below is a very long list of quotes from gun and defense industry media showing that silencer and suppressor have been used interchangeably for many years, leading up to the focused PR campaign to switch to suppressor. Earlier, suppressor was only used for flash suppressor. Suppressor started to become fashionable only the 90s, and even up to 2010 there was no distinction. After 2010, media sometimes preferred suppressor, and sometimes said silencer was wrong, but almost always only when the topic was advocacy or op-ed to change the laws restricting silencers in the US. Even after 2014, SilencerCo hasn't changed its name, and many US silencer manufacturers still call their products silencers. GemTech for example categorizes many products as "silencers" and has it in the product names, but argues "Silencer, Muffler, Suppressor, Can... take your pick! The most scientifically accurate descriptor is, suppressor.". Saying something is "scientifically accurate" doesn't make it scientific. GemTech offers no "scientific" evidence that suppressor is accurate. It's not a science question, it's a lexicographic question. The simple fact is that the definition of silence and suppress is not what these guys are claiming it is. Surefire likes suppressor but makes sure you can see their suppressors are silencers.. AAG calls them silencers. AMTAC. Liberty.

Search Guns&Ammo prior to 2010 and the word suppressor only appears when referring to a flash suppressor. Articles during that period use silencer when they mean silencer. For example: Even after 2010, the gun media casually treats silencer and suppressor as interchangeable. With only one or two exceptions, the only time the stop to argue that silencer is wrong is when they are writing an advocacy article calling for loosening restrictions on silencers, and addressing public misconceptions. Some of these articles specifically call out the fact that some aficionados prefer suppressor, but they normally chuckle and roll their eyes. Though the advocacy articles frequently fault Hollywood for making silencers seem truly silent, or at least very quiet, one non-op-ed product review affirmed that the silencer actually did work as seen in the movies. A Defense Electronics article described the tactical use of silencers, and said that they are effective in concealing a shooter from the enemy, contradicting the claim that they serve only to protect hearing and not to evade capture or elude police.

 * "The PC wing of gundom (and there is one, but for generally good reasons, and not to an extreme) will insist that these devices are not really silencers because the guns upon which they are mounted still make a very discernible noise. I'm going to continue to use the term 'silencer' since that is the legal name for them and that's the term that the inventor used many years ago. --Dennis Bratland (talk) 23:50, 27 February 2018 (UTC)


 * It's true that suppressor has been used to refer to gun parts for decades, but every source I found before the mid-1990s is referring to flash suppressors, not silencers. The article has a 1985 patent saying that is the earliest example of suppressor used to refer to noise reduction, and it sounds reasonable. For 116 years silencer has been and still is the main term. Muffler and can have been around too. Suppressor slowly gained traction from the mid 1980s and started to show up on the radar in some gun media in the 90s, but it was only after 2000, and especially after 2010, that a conscious decision was made to use suppressor as a euphemism for silencer, after that term had acquired a sinister connotation. That's basically a neologism. And after the NRA assumed the reason the public thinks they are whisper-quiet. The fact is that 1) movies get everything wrong. It's art, not life 2) There is evidence that silencers do in fact, in certain cases, allow shots to be fired without attracting attention. It depends heavily on the circumstances, and there's more to it than just screwing a can onto any old gun, but to suggest that they have no covert function, and couldn't benefit criminals, is highly questionable. --Dennis Bratland (talk) 17:49, 28 February 2018 (UTC)

Sound moderator terminology use in the UK
I don't really see the point all the details about the use of sound moderator in the UK: and. The terminology section is explaining how the word silencer is equivalent to car muffler in the UK, in the context of the claim that silencer only means "total silence" rather than merely sound reduction. It's nice to know that sometimes the term sound moderator has been used in the UK, but it's tangential to the subject of that paragraph. The question we don't have any sources for is "how common is the term sound moderator in the UK"?On the topic of whether and when silencers are allowed in shooting competitions, it's not relevant to the terminology section. We don't really have a section right now about the rules for using silencers in hunting sport or competitions other than government regulations. We could add a section on that topic.It can't be emphasized enough that the whole "debate" over what to call a silencer was a manufactured controversy created by the US NRA as part of a political campaign kicked off in 2011 to loosen regulations in US. Prior to that, and outside of that context, there is no controversy over what to call a silencer. We shouldn't be writing this in a way that implies there was ever a problem with the word until the NRA made it a problem in 2011. --Dennis Bratland (talk) 22:24, 12 April 2018 (UTC)


 * Adding to what editor Dennis Bratland has noted regarding names (e.g., silencer, suppressor, moderator, etc.) for these devices, I'll add some more specifics. There probably is no "one" "correct" term. In the United States, the technical legal term in the law itself is silencer. See the definition in, and the definition provisions of the National Firearms Act at . I think this point was covered briefly earlier on this talk page, but if the citations to these statutes were listed, I missed them. Famspear (talk) 15:13, 12 June 2018 (UTC)
 * It's not just the legal term in the US. It's also the name bestowed on it by its inventor. And the name used by virtually all sources for 100 years. Even technical gun media preferred silencer until very recently. It's just false to imply there is any ambiguity here. It had always been called a silencer, and silencer is the correct term. It was until it became politicized and the need for a euphemism was identified for political reasons. Prior to that, suppressor was primarily used to distinguish a flash suppressor from a sound silencer. We can trace the history of this and see with our own eyes the deliberate, cynical Newspeak shift from silencer to suppressor by the gun media and the gun industry.Consider the American Silencer Association. If silencer was "wrong", you'd think these would be the very ones who would know best that it is wrong. But their members included companies like SilencerCo, and their catalogs were filled with products they called silencers. Later, the NRA coordinated their PR efforts with the ASA, and they changed the S to Suppressor. But SilencerCo didn't change their name, and to this day many manufacturers have no problem with the word silencer.The argument that silencer is incorrect because silencers don't make guns perfectly silent has been demonstrated to be false: that's not what silencer means. If you insist on interpreting the silencer to mean absolute quite, then suppressor has exactly the same problem. A literal-minded Drax the Destroyer would take suppress just as literally as silence. But in fact, words don't work that way. There's a reason the phrase "absolute silence" exists, because silence doesn't imply total quiet.I'll just note that the propagandistic sources that insist silencer is "wrong" don't show their work. They don't cite any dictionaries or linguistic sources. They simply assert that silence means total quiet, ignoring the evidence that it does not. --Dennis Bratland (talk) 17:21, 12 June 2018 (UTC)

– After this article's move from "suppressor" to "silencer", the article has become the clear primary topic for "silencer", with 6x as many pageviews as the scientific term. Since most people agree the proper name for this is a "silencer", it should be moved to the primary namespace ZXCVBNM (TALK) 23:51, 14 November 2019 (UTC)

 * Oppose – the rationale makes no sense; changing from suppressor has no influence on whether it's primary for silencer, which is an ambiguous term that deserves disambiguation. Dicklyon (talk) 02:29, 15 November 2019 (UTC)
 * Support per clear usage preference and WP:ASTONISH. -- Netoholic @ 04:06, 15 November 2019 (UTC)
 * As a Brit, I would be astonished to find myself reading an article about firearms rather than one about car parts. Narky Blert (talk) 15:34, 18 November 2019 (UTC)


 * Oppose. Here in Britain the main use of "silencer" is the device to make internal combustion exhausts quieter. Anthony Appleyard (talk) 06:04, 15 November 2019 (UTC)
 * Are local anecdotes now appropriate in RM discussions over demonstrable numbers? Clearly when this is made primary, a hatnote will point to muffler to cover this meaning. The muffler meaning is not primary, as silencer is not currently a primary redirect anyway.  It has no bearing on this discussion. -- Netoholic @ 07:50, 15 November 2019 (UTC)
 * This RM asserts that the firearms use is the primary topic for "silencer". That "local anecdote" is an opinion that it isn't. Neither are backed up by "demonstrable numbers". Here are some numbers: |Muffler|Silencer|Silencer_(genetics)|Silencer_(band)|Silencer_(comics): Silencer (firearms) article is not clearly more likely than all the other topics combined.

 * Comment – No reason support or oppose. It seems harmless to do this move, but then again, can someone explain which specific, existing problem (not WP:BEANS) that this would solve? Thanks. --Dennis Bratland (talk) 21:11, 15 November 2019 (UTC)
 * The fact that most people search for "silencer" wanting the gun part and are forced to click through the disambiguation to reach it. A minor problem, but then again, that could be said for the vast majority of requested moves.ZXCVBNM (TALK) 23:22, 15 November 2019 (UTC)
 * I agree, but how do you know it's a fact and not a supposition? If there's clear evidence that many readers are doing that then I would !vote support. Many more than the ones who are looking for muffler, silencer (genetics), silencer (band) and so forth. It's plausible but how do we know? To be clear, if I thought this was pointless and equivalent, like flipping back and forth between equally valid WP:ENGVAR or MOS:DATEVAR choices, I'd !vote oppose. But I wouldn't go that far; I think there's enough merit that I'm not against it. --Dennis Bratland (talk) 00:17, 16 November 2019 (UTC)
 * Articles are mostly not accessed by title search, and when a disambig page comes up, an extra click is pretty much a non-problem, so this obsession with primarytopic grabbic seems like a generally bad idea to me. Dicklyon (talk) 05:15, 16 November 2019 (UTC)


 * Oppose. The primary meaning in British English is - by some distance - what Americans call a muffler (a word not used in British English). The firearms sense is mainly known in UK from US movies and TV. No worldwide WP:PTOPIC. Narky Blert (talk) 15:31, 18 November 2019 (UTC)
 * Oppose. It's not at all clear that the firearms use is primary. Shhhnotsoloud (talk) 15:33, 20 November 2019 (UTC)
 * Oppose per WP:ENGVAR. To the British, a silencer is what the Americans call a muffler. Obviously the firearms term is well-understood even in this country where firearms are not in common circulation, but it's certainly not primary. -- Necrothesp (talk) 10:43, 21 November 2019 (UTC)

In Australia, use and ownership of silencers is generally limited to government, security and law enforcement use only and thus prohibited for civilians.
Generally speaking nothing prohibited in Australia, one just need to obtain special permission or licence. Silencers could be own by people who need them for business use. For example if one have business and register it for pest shooting then (s)he can use silencer. However in reality it means that effectively silencers unreachable for general public.101.188.233.21 (talk) 09:25, 26 March 2020 (UTC)

Subsonic ammunition
The subsonic ammunition article seems to imply that the only reason for using "subsonic ammunition" is to reduce the loudness of the shot.

This article generally talks about a variety of ways of reducing the loudness of a shot.

Therefore, I propose merging that article into the silencer (firearms) section of this article.

(If there were some *other* reason for using "subsonic ammunition", then it would make more sense for it to be an independent article). --70.189.72.160 (talk) 01:13, 4 October 2020 (UTC)
 * Weak oppose, on the grounds that there is another difference, in that for a given amount of energy, the subsonic ammunition has more momentum, which means greater penetration and stopping power. This is because energy is proportional to mv2, while momentum is proportional to mv. Klbrain (talk) 16:17, 4 May 2021 (UTC)

Earliest use
The current entry for first use cites a 1985 patent. This seems like original research to me, and I have marked it as such. Additionally, I have found the following after only a cursory search, dated 1968: So, not only is the current entry original research, it also seems to be incorrect. I am not suggesting replacing and re-dating it, but removing the claim entirely. A reliable expert source which actually states the first use of the term for noise suppression would be required for it to be included in the article.
