EXPERIENCE HEARING LOSS: Click on the following simulation links to discover how sensorineural hearing losses affect hearing. This type of hearing impairment is by far the most frequent and is caused by a dysfunction of the inner ear. The first simulated hearing loss is a mild one.The second simulated hearing loss reflects a typical "sloping" (i.e., less hearing in the high frequencies) moderate hearing loss.


A hearing loss can happen when any part of the ear or auditory (hearing) system is not working in the usual way. Hearing loss that occurs within the Speech Banana can slow the development of a child's language and speech abilities which, in turn, can profoundly interfere with learning.

A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities.

How can hearing aids help? Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss.
