What Is Sensorineural Hearing Loss?

Published on Jul, 01, 2021

To best understand what sensorineural hearing loss is, it’s important to first understand how we perceive sound.

When sound waves reach your ears, they pass through your ear canal and cause your eardrum to vibrate. Your three inner ear bones register these vibrations and amplify them into your cochlea.

The vibrations reach this snail-shaped sound receptor and cause the fluid within to move microscopic hairs. The movement of these hair cells triggers neural signals to the brain. When the brain receives them, it interprets them, so we hear voices, music, and other noises for what they are.

Sensorineural hearing loss is the degradation of either the tiny hair cells or their neural transmitters or both. This most often occurs as a result of aging and is called presbycusis, which is the most common form of hearing loss. 

Overexposure to loud sounds, head trauma, genetic predisposition, and certain drug use can also result in sensorineural hearing loss.
