Auditory neuropathy (AN) occurs when the nerve system of the inner ear fails to process sounds coming from the outer ear.

The outer ear sends vibrations to the inner ear during the hearing process. Hair cells in the inner ear break down the vibrations into electrical signals. These are sent to the brain. The brain filters them as sound. There is debate about the exact cause of AN. It may be due to:
- Damage to the hair cells in the inner ear
- Bad connections between the hair cells in the inner ear and the nerve to the brain
- Damaged nerve
- A mixture of these problems
