In some cases, the cause may involve damage to the inner hair cells-specialized sensory cells in the inner ear that transmit information about sounds through the nervous system to the brain. Researchers report several causes of auditory neuropathy. Sounds may fade in and out or seem out of sync for these individuals. For example, a person with auditory neuropathy may be able to hear sounds, but would still have difficulty recognizing spoken words.

The number of people affected by auditory neuropathy is not known, but current information suggests that auditory neuropathies play a substantial role in hearing impairments and deafness. It can affect people of all ages, from infancy through adulthood.
