Hyperacusis is described as an increased sensitivity to certain sounds. Severe hyperacusis may result in isolation and overuse of hearing protection and it can ultimately affect concentration and social interactions. Hyperacusis may also lead to phonophobia or a fear of sounds.
Loudness discomfort levels at various pitches are the typical measure of hyperacusis. This measurement uses loudness scaling to determine how loud is uncomfortable for a variety of sounds.
The goal of hyperacusis treatment is increased tolerance for hyperacusic sounds and is usually attained with sound enrichment via sound generators. These devices may include: Neuromonics Oasis (a more detailed description is available under on the Tinnitus page), ear level sound generators, or personal listening devices.
