Hyperacusis is an increased sensitivity to sound and a reduced tolerance for environmental noise. Definitions vary, but the condition often centers on damage to or dysfunction of the stapes bone, the stapedius muscle, or the tensor tympani muscle, and it is commonly grouped into four subtypes: loudness, pain, annoyance, and fear. It can be a highly debilitating hearing disorder.
