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.

NIDCD Balance Disorders Center provides an overview of balance disorders.

The most common type of dizziness, benign paroxysmal positional vertigo (BPPV) is a type of dizziness that lasts seconds. It is most often provoked by turning over in bed. It is diagnosed with the Dix-Hallpike maneuver. This maneuver determines the affected ear and which Epley maneuver to perform. is a great resource for vestibular disorders for both patients and providers.

Falls can be deadly in older patients with dizziness or imbalance issues. This article from the New York Times has great fall prevention strategies.
