Misophonia is a condition where the person has a select hatred to sounds, by narrative or by nervous sensitivity. They are usually the only character(s) who lacks the tolerance to these sounds, and are mocked in-universe, or by plot-serving means.
In a certain Planet of Hats, the tolerance to sounds are the hats there that are rarely rejected. Most people consider "normal" sounds to be neutral, such as reproducing sound effects with the mouth, humming, whistling, singing, etc., while those with misophonia are acutely sensitive to these. Because of this, they are considered to be aliens and not their real kind, because it was too rarely detracted against. When this happens, they are most likely to be ostracised, publicly beaten, falsely rumored of monstrosity, or all and also become a Hero with Bad Publicity and a Socially Awkward Hero. Truth in Television: While this condition was discovered in 2000, this trope is Older Than They Think. There have been cases of famous people having this by complaining about the sounds around them at certain times. If a villain has misophonia of this type, then they count as a Tragic Villain if that is their main issue, or one of them. They are either embedded within their neurological disorder(s), or added to it through traumatic events.
Generic, theme-serving, oppositional characterization
Often, some characters, usually villains, are depicted as having the opposite views of sounds, generally music, for the sake of An Aesop, Foil-run villainy, or both. This type means that the character is misophonic For the Evulz instead of being neurotypical.
A subtrope to Sensory Abuse and Berserk Button. Compare Trauma Button (from Teach Him Anger when this was added to the character), and Your Normal Is Our Taboo. Those with misophonia are often a Fish out of Water who view the bodily sounds as signs of being Conditioned to Accept Horror, self-indulgent, overall selfish, and Too Dumb to Live. Reactions to these sounds include Brain Bleach, Rant-Inducing Slight, and or Freak Out. If this applies to the audience, then this is Most Annoying Sound combined with Squick. Especially in real life, there are cases where the character may sometimes indulge in some of these sounds, making it very likely to zig-zag. As part of its extremely complex functionality, it never counts as hypocrisy, contrary to popular belief. This trope is about psychological harm and demoralization. If this actually causes obvious physical harm instead of only distress, then it is Weaksauce Weakness, Brown Note, and the verbal equivalent Weapons-Grade Vocabulary.
