Talk:Deafness/removed material

Explanation
''(Reason for taking out: Basically restates what I wrote in the intro, and the stuff on how a group of people "don't like it" is not relevant in this early section. That infomation will need to go near the end, once the topic is fully explained. In addition that material will need to be checked for a global (rather then US) relevance). —— Eagle (ask me for help) 23:36, 2 December 2006 (UTC)''

Hearing impairment can affect any creature that hears. Sound varies in amplitude (loudness) and frequency (pitch). Most animals are able to sense sound energy, but no individual animal species can detect all frequencies of sound at all amplitudes (levels of loudness). In fact, although there is much overlap, each species has a different set of audible sounds. Within that range of audible sound, each species is attuned to an even narrower range of pitches that it hears best — usually the sorts of sounds that are important for survival. In social animals, like humans, who use sound as a primary means of communication (spoken language), hearing is most sensitive for the pitches that are produced in speech.

The medical term hearing impairment has become controversial due to very strong objections from the deaf community who refute the implication of a disability. Those who consider themselves part of Deaf Culture feel offended by the term "impaired". However, not all people, especially those who become deaf in later years, may make this distinction.
