Diplacusis

/ˌdɪpləˈkjuːsɪs/ noun

Definition

A hearing condition where a single sound is perceived as two different sounds, often at different pitches, usually in different ears.

Etymology

From Greek di- (two) + plakousis (hearing). First described in medical literature in the 19th century as an auditory phenomenon related to ear or nerve damage.

Kelly Says

People with diplacusis experience a bizarre middle ground between hearing perfectly and being deaf—they hear the same piano note as two slightly different pitches, making music torture!
