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 ().
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.

He cites research by scientist David Baguley into hyperacusis, a condition that makes certain people extremely sensitive to sound and can be linked to trauma. “I think there might be something ...
People with misophonia display hypersensitivity to certain pattern-based noises such as the sound of chewing, slurping, finger tapping, foot shuffling, throat clearing, pen clicking, and keyboard tapping; people with misophonia respond to triggering sounds with emotional distress and increased hormonal activity of the sympathetic system. [18]
The sufferer becomes anxious to get away from the source of the loud sound and may get headaches. [1] It may also be related to, caused by, or confused with hyperacusis, extreme sensitivity to loud sounds. [5] Phonophobia also has been proposed to refer to an extreme form of misophonia. [6]
Hyperesthesia is a condition that involves an abnormal increase in sensitivity to stimuli of the senses.Stimuli of the senses can include sound that one hears, foods that one tastes, textures that one feels, and so forth.
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 ...
Cat hearing is also extremely sensitive and is among the best of any mammal, [17] being most acute in the range of 500 Hz to 32 kHz. [21] This sensitivity is further enhanced by the cat's large movable outer ears (their pinnae), which both amplify sounds and help a cat sense the direction from which a noise is coming. [19]
