title: A compact disc containing simulations of hearing impairment.
abstract: The author has produced a compact disc (CD) which contains a series of simulations of the effects of cochlear hearing loss. The following aspects are simulated: threshold elevation combined with loudness recruitment; reduced frequency selectivity; and threshold elevation, loudness recruitment and reduced frequency selectivity all together. The effects are demonstrated using speech in quiet and in a background of noise, and using a piece of music with a wide dynamic range. The CD also includes simulations of the effect of having a conventional 'linear' hearing aid, and of having aid incorporating dual-channel fast acting compression. Finally, the CD contains demonstrations of the 'occlusion effect' and the benefits of having a deeply fitting earmould or hearing aid. The purpose of this note is to describe some of the uses of the CD for teaching and educational purposes and to indicate which tracks will be most effective for specific purposes.
