Drunken

In the line "was invented by Robert Foulis, a drunken Scotsman who", what does drunken add to anything? 173.29.0.124 (talk) —Preceding undated comment added 09:33, 20 November 2010 (UTC).

Trivia Section

The 'trivia' section seems completely unnecessary, even for an entry of this importance rating. Further, train horns are far more commonplace in hockey arenas to denote a scored goal, and I have never once heard a fog horn sound during a hockey game.

Frequency (Hz) of tones related to vessel size

—Preceding unsigned comment added by 68.50.72.8 (talk) 14:04, 13 June 2009 (UTC)

The frequency of a foghorn is related to the size of the vessel, so large ships have deeper tones, and smaller vessels smaller tones. land-based foghorns (e.g. lighthouses) have very deep tones.

The Fog Gong — Preceding unsigned comment added by Zarny52 (talk • contribs) 18:46, 22 December 2011 (UTC) One type of fog(signal) not mentioned was the GONG. It was shaped like a large shield with the concaved side facing to sea. It was struck on the back with a solenoid striker. To make make the sound of the gong the right length. The striker would re-hit The gong but not back off. This stopped the reverberations of the gong. It made for a very funny sound. Bong.... then a very dud sounding..Bonk!! — Preceding unsigned comment added by Zarny52 (talk • contribs) 18:43, 22 December 2011 (UTC)

low tones a mistake?
Low pitches are rather non-directional to human ears. That's why many stereo audio systems have just one subwoofer.

Has anyone ascertained if the low tones of fog horns really are superior for locating dangers in fog? By the article it sounds like low tones were chosen just on the anecdotal observation of one person.--23.119.204.117 (talk) 04:13, 22 August 2017 (UTC)

obsolescence
In this section, there is a misprint. The sentence "if the laser beam is reflected" should be "if the laser beam is not reflected" 143.159.160.91 (talk) 09:18, 22 April 2022 (UTC)


 * @143.159.160.91 correction:

"if the beam reflects back" should be "unless the beam reflects back" 143.159.160.91 (talk) 09:24, 22 April 2022 (UTC)
