Hyperacusis
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. It is often categorized into four subtypes: loudness, pain (also called noxacusis), annoyance, and fear. It can be a highly debilitating hearing disorder.
There are a variety of causes and risk factors, with the most common being exposure to loud noise. It is often coincident with tinnitus. Proposed mechanisms in the literature involve dysfunction in the brain, inner ear, or middle ear.
Little is known about the prevalence of hyperacusis, in part due to the degree of variation in the term's definition. Reported prevalence estimates vary widely, and further research is needed to obtain strong epidemiological data.
Hyperacusis symptoms can include an increased perception of the loudness of sounds (loudness hyperacusis), pain (noxacusis/pain hyperacusis/sound-induced otalgia), annoyance, and/or fear in response to sounds by which most people are unaffected. It may affect one or both ears. The majority of patients experience bilateral symptoms but often have one ear that is more affected than the other. Annoyance hyperacusis is often considered synonymous with misophonia. Fear hyperacusis is often considered synonymous with phonophobia. Many researchers more narrowly define hyperacusis to only include loudness hyperacusis and pain hyperacusis.
Hyperacusis can also be accompanied by tinnitus. The latter is more common and there are important differences between their involved mechanisms.
Hyperacusis can result in anxiety and stress. Avoidant behavior is often a response to prevent the effects of hyperacusis and this can include avoiding social situations.
Loudness hyperacusis is characterized by an increased perception of the loudness of sounds. It is often associated with certain volumes and/or frequencies. It can occur in children and adults, and can be either "short-term" in a duration of weeks to less than a year before recovery, or, less commonly, "long-term," spanning years and in some cases becoming permanent. Sensitivity is often different between ears.
In some instances, hyperacusis is accompanied by pain, which is known as noxacusis. Noxacusis is characterized by pain resulting from sounds, often initiated at certain volumes or frequencies. Pain can be immediate or delayed, and it sometimes persists for an extended period of time following exposure. Pain can be acute or chronic, and is often described as stabbing, burning, throbbing, or aching. In healthy listeners, pain from sound is not typically experienced until the volume exceeds approximately 120 decibels.
