Hearing Loss

National Institute for Deafness and other Communication Disorders (NIDCD) has much information on hearing loss information and treatment. Specifically, it provides an introduction to the many types of ear disorders, how to protect your hearing, and information for parents.

Simulations of What Hearing Loss Sounds Like

  • These simulators are useful for demonstrating the loss and distortion of acoustic information. They are also useful to demonstrate the mental work required to understand speech with hearing loss. This simulation of mild and moderate hearing loss is similar to the degree of hearing loss that is associated with noise exposure and aging.

  • Cochlear implants are surgically implanted devices that bypass the damaged structures of the inner ear to create a sense of sound. This simulation and a more in-depth simulation demonstrate the poor pitch perception provided by cochlear implants. CIs provide enough information for good speech perception in quiet. However, the poor clarity makes it difficult to hear in background noise and music.
