Computer models of the auditory periphery provide a tool for -formulating theories concerning the relationship between the physiology of the auditory system and the perception of sounds both in normal and impaired hearing. However, the time-consuming nature of their construction constitutes a major impediment to their use, and it is important that transparent models be available on an 'off-the-shelf' basis to researchers. The MATLAB Auditory Periphery (MAP) model aims to meet these requirements and be freely available. The model can be used to simulate simple psychophysical tasks such as absolute threshold, pitch matching and forward masking and those used to measure compression and frequency selectivity. It can be used as a front end to automatic speech recognisers for the study of speech in quiet and in noise. The model can also simulate theories of hearing impairment and be used to make predictions about the efficacy of hearing aids. The use of the software will be described along with illustrations of its application in the study of the psychology of hearing.
计算机听觉模型为制定有关听觉系统生理学与正常和受损听力下声音感知之间关系的理论提供了工具。然而，它们的构建耗时性质构成了其使用的主要障碍，重要的是，透明模型应以“现成”的方式提供给研究人员。MATLAB 听觉外围 (MAP) 模型旨在满足这些要求并免费提供。该模型可用于模拟简单的心理物理任务，如绝对阈值、音高匹配和前向掩蔽，以及用于测量压缩和频率选择性的任务。它可用于自动语音识别器的前端，以研究安静和噪声中的语音。该模型还可以模拟听力障碍理论，并用于预测助听器的效果。本文将介绍该软件的使用，并举例说明其在听觉心理学研究中的应用。
