Hyperacusis is an abnormal condition in which the complex electrical signals generated by sound vibrations are misinterpreted, confused, or exaggerated. The balance system uses lower-frequency sensations to help maintain posture in relation to gravity. Sounds are detected as energy vibrations the human cochlea can hear best the frequencies associated with speech. Both systems are filled with fluid whose movement stimulates tiny sensory cells. The hearing and balance systems of the inner ear are interconnected. It has not been sufficiently studied in the adult population and is often ascribed to psychological conditions rather than being recognized as a physiologic symptom of cochlear or vestibular damage. Hyperacusis can be associated with auto-immune disorders, traumatic brain injury, metabolic disorders, and other conditions. In serious cases, it can cause seizure-like activity in the brain. 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. The particular symptoms of cochlear hyperacusis and vestibular hyperacusis can help physicians and audiologists distinguish between the two disorders. Hyperacusis is the perception of unusual auditory sensitivity to some environmental noises or tones.
