Misophonia is a condition in which a person reacts extremely negatively to certain sounds that most people take little or no notice of. This disorder is not caused by a hearing impairment and elicits excessively negative and immediate emotional and physiological responses. This sensitivity to certain sounds can have a negative effect on a person’s life causing problems with activities of daily living.
Hyperacusis is a condition that causes a person to be unable to tolerate everyday noise levels without discomfort or pain. This condition is frequently initiated by a loud noise exposure but can also be induced by certain medications. Hyperacusis arises from a problem in the way the brain’s central auditory processing centre perceives noise. It can often lead to pain and discomfort.
