声音空间定位测听系统的设计与实现

目的 设计并实现一种可判别及评价人耳声音空间定位能力的系统。方法 人耳对声音的空间定位是听学和一个基本功能，通过对声音的物理特性及人耳的吸觉特性的分析，给出声源在方向和距离两方面的定位方法，在充分利用计算机技术的基础上,利用尽量少的辅助硬件,提出一种方便可行的测试人耳声音空间定位能力的方法，该系统具有纯音测试、噪音测试、音乐测试及语音测试共4种测试模式，可通过测试参数MAA来判别受试者对声音的空间定位能力。结果 本系统经初步实验及临床验证，邓得了比较好的测试结果。结论 本方法在判别及评价人耳声音空间定位能力方面具有一定的应用价值。

Devising and initial realization of testing hearing system for sound location

AIM To design and realize a system which can distinguish and evaluate people's ability to localize sound. METHODS Through analysing the physical features of sound and the auditory property of ear, the author advanced a method to localize sound both in horizontal and vertical directions, and presented and realized a simple and feasible sys-tem for testing hearing based on making full use of computer technology. This system has four test modes, and can distinguish and evaluate people's ability to localize sound through parameter MAA. RESULTS After initial experiments and clinical confirmation, a preferable result has been achieved. CONCLUSION The method presented in this paper has a certain applicable value in distinguishing and evaluating people's ability to localize sound.
