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.
作者制作了一张光盘（CD），其中包含一系列关于耳蜗性听力损失影响的模拟。模拟了以下几个方面：阈值升高与响度重振；频率选择性降低；以及阈值升高、响度重振和频率选择性降低同时出现的情况。这些影响通过安静环境中和有噪声背景下的语音，以及一段具有宽动态范围的音乐来展示。该CD还包括佩戴传统“线性”助听器的效果模拟，以及佩戴具有双通道快速作用压缩功能的助听器的效果模拟。最后，该CD包含了“堵耳效应”的演示以及佩戴深耳道式耳模或助听器的益处。本说明的目的是描述该CD在教学和教育方面的一些用途，并指出哪些音轨对于特定目的最为有效。
