Hyperacusis is the perception of unusual auditory sensitivity to some environmental noises or tones. The effects of hyperacusis can range from a mild sense of unease to a complete loss of balance or upright posture with severe ear pain. Cochlear hyperacusis can be treated with acoustic therapies such as tinnitus retraining therapy (TRT). Vestibular hyperacusis, however, continues to go untreated or unrecognized in many cases.
