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 neuroatypical.
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 and or Freak Out. If this applies to the audience, then this is annoying 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. Also see Misophonia Gag, where such a reaction is used as a one-off instance for comedy or drama purposes but rarely (if ever) made a point of actual characterization.

- Kaguya from Kaguya-sama: Love Is War is shown at several points in the manga to be very sensitive to loud noises (with a bonus chapter establishing that this extends to any strong stimuli).

- The Twilight Zone (1959) features this in "Sounds and Silences".

He adds that he hated having to be so quiet all the time and thus surrounds himself with loud noises. His callousness results in Laser-Guided Karma when he suddenly becomes misophonic himself. Everything from dripping water to soft music causes him agony. Convinced that it must be a psychiatric issue, he sees a therapist. Annoyed by the sound of her voice, he decides to shut her out and happily smiles at having a moment of the silence he hated so much before. His joy is short-lived. He eventually discovers that he's permanently lost the ability to hear anything at all.
- In EarthBound Beginnings, the Big Bad alien Giegue canít stand the sound of his childhood lullaby, because it reminds him of his childhood and his connection to humanity. The Final Boss battle exploits this. Because he is too powerful to defeat normally, you instead sing that lullaby to him repeatedly, causing him to get increasingly angry and desperate for you to stop until he finally leaves. Unfortunately, his defeat by these means leads to him seeing his humanity as a weakness, and by the time of the sequel, has eliminated it entirely to become the all-powerful Eldritch Abomination Giygas, with zero remaining human traits.
