Musical ear syndrome

How it works

The music sounds real. It has a melody, a rhythm, and often words. It is usually familiar: hymns, carols, folk songs, or pop songs from the person’s youth. It can play for hours. Some people hear one short loop over and over¹.

The cause is a quiet ear. When the ear sends little sound to the brain, the parts of the brain that store music start to run on their own. They release stored patterns as if they were input. The same thing happens in the visual system. People who lose their sight sometimes see clear images of people or patterns. That is Charles Bonnet syndrome³. Musical ear syndrome is the hearing version¹.

It is most common in older people with serious hearing loss. Tinnitus, living alone, and some medicines make it more likely¹. About 2% to 3% of people with profound hearing loss report it¹.

It is not a mental illness. The key sign is insight. The person knows the music comes from inside their head. In psychosis the sounds are believed to be real, and they are usually voices, not music¹.

Hearing aids sometimes reduce or stop the music, because they give the brain real sound to work with¹. Playing actual music can also push the phantom music aside for a while.

History and culture

The neurologist Oliver Sacks made the condition widely known in his 2007 book Musicophilia². He describes patients who heard entire symphonies, and one who heard nothing but Christmas carols. Many of them had never told anyone, because they feared it meant they were losing their minds.
