摘要
目的探讨声源定位仪研制与初步应用。方法在计算机技术的基础上,利用角度传感器、角位变送器和其他相关技术,设计出声源定位仪系统,用该系统测试正常受试者。结果用此声源定位仪系统测试正常受试者,正常受试者在正前方1.2米处的声源定位偏差是2.5°,男性和女性定位能力无明显差异(P>0.05)。结论此声源定位仪定量的测试受试者水平方向的定位能力,操作简单,易应用于临床。
OBJECTIVE To explore the manufacture of a sound localization apparatus and its primary application. METHODS Based on the computer technology and using the angle sensor, angle transmitter and other correlated technology, a system of sound localization was manufactured and used it to test normal person. RESULTS The normal persons were tested with the system of sound localization, and found that the localization deviation was 2.5° before 1.2 m in the vertical front. There are no difference between the male and female （P 〉0.05）. CONCLUSION The sound localization apparatus can test the localization ability of person, and it can be used in simply and reasonably.
