Simulation of Effects of Cochlear Damage
This demonstration consists of two sound passages (speech and music) electronically filtered so as to simulate the effective sounds reaching the ears of listeners who have (a) Normal ears, or those with either (b) Moderate or (c) Severe Damage. Typical audiograms for such listeners are shown below.Click on the icon of the condition you wish to simulate.
Note that these simulations do not include the perceptual distortions of loudness (so-called "recruitment") which accompany such hearing impairments, so the sounds you will hear are only rough approximations to the sound perceptions of people who have such hearing impairments (when unaided by hearing instruments).
You will need a sound board and speakers to listen to these sounds. The sound files are in .WAV format and range between 1 and 2 MBytes each. These demonstrations are not recommended if you are connecting via a slow link (e.g. via modem).
