Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone , stapedius muscle or tensor tympani ( eardrum ).
Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. Although the ear is the primary organ for sensing low sound, at higher intensities it is possible to feel infrasound vibrations in various parts of the body.
Misophonia (or selective sound sensitivity syndrome) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues.These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses not seen in most other people.

Saccular acoustic sensitivity is a measurement of the ear's affectability to sound. The saccule's normal function is to keep the body balanced, but it is believed to have some hearing function for special frequencies and tones. Saccular acoustic sensitivity is considered to be simply an extension of the sense of hearing through the use of the ...
Annoyance effects of noise are minimally affected by demographics, but fear of the noise source and sensitivity to noise both strongly affect the 'annoyance' of a noise. [42] Sound levels as low as 40 dB(A) can generate noise complaints [43] and the lower threshold for noise producing sleep disturbance is 45 dB(A) or lower. [44]
Kelly Ripa “As early as I can remember, certain sounds of eating bothered me,” Kelly revealed during a 2012 interview on ABC’s 20/20. “The sounds of people chewing gum can really enrage me.”
The second component is known as "distortion" or "clarity loss" due to selective frequency loss. [8] Consonants, due to their higher frequency, are typically affected first. [7] For example, the sounds "s" and "t" are often difficult to hear for those with hearing loss, affecting clarity of speech. [9] NIHL can affect either one or both ears.
These included 2,291 whistles, 2,288 burst-pulses — a rapid series of clicks sometimes associated with aggression — 5,487 low-frequency tonal sounds and 767 percussive sounds.
