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. Multiple factors may represent the underlying cause of AN. It may be due to: Damage to the hair cells in the inner earBad connections between the hair cells in the inner ear and the nerve to the brainDamaged nerveA combination of these problems
AN may cause: White noise—the sound is heard, but the word is not clearSounds to tune in and outWords and sounds to seem out of sync
Ringing in the ears—
The level of hearing loss can vary from mild to severe. People with AN may have trouble picking out words. Many cases involve children.
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include: Auditory brainstem response (ABR) to measure brainwave activityOtoacoustic emissions (OAE) to record how the cells in the ear respond to clicking sounds
Goals of treatment include: Saving current hearing skillsRestoring lost hearingFinding new ways of communicating
Talk with your doctor about the best treatment plan for you. Treatment options include the following:
Working with a team of specialists, including:
Otolaryngologist (ENT)—doctor specializing in disorders of the ear, nose, and throatAudiologist—healthcare professional who specializes in hearing lossSpeech-language pathologist—healthcare professional who specializes in communication disorders
Using technology, such as:
—surgically implanted electronic devices that stimulate the auditory nerve to send information to the brain
Hearing aidsListening devices such as frequency modulation (FM) systems
Having speech-language therapy, such as:
Sign languageSpeech-reading—also known as lip-readingExercises combining listening skills with technology
In many cases, the exact cause of AN is unknown. However, these steps may help: If you are pregnant, ask your doctor how you can avoid infectionsTalk to your doctor if you have any conditions related to AN
