Let South Carolina Hear: Hearing Simulation

In this simulation you can 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.
