How does hearing work?
Hearing is a complex process. It starts with sound waves entering the outer ear and traveling through the ear canal. They hit the eardrum, which vibrates in response. The resulting vibrations move through the middle ear to the inner ear. The inner ear houses specialized cells that translate the vibrations into electrical signals. The auditory nerve carries these signals to the brain. The brain interprets the signals as sound. A problem at any step in the process can cause the profound hearing loss of deafness.

Sudden sensorineural (“inner ear”) hearing loss (SSHL), commonly known as sudden deafness, is an unexplained, rapid loss of hearing either all at once or over a few days.

How is sudden deafness diagnosed?
If you have sudden deafness symptoms, your doctor should rule out conductive hearing loss—hearing loss due to an obstruction in the ear , such as fluid or ear wax. For sudden deafness without an obvious, identifiable cause upon examination, your doctor should perform a test called pure tone audiometry within a few days of onset of symptoms to identify any sensorineural hearing loss.
