本标准中描述的方法提供了可用于评估声音定位性能的数据，这些数据可用于开耳和使用人类受试者的头戴设备。该标准描述了三种测量方法:1）使用8个扬声器测量位置识别性能的低复杂度方法；2） 使用36个扬声器测量定位误差的更复杂、更稳健的方法；3）一种测量降级定位线索对36个扬声器的视觉搜索时间的功能影响的方法。该标准规定了受试者资格标准、测试空间声学要求、三种方法的细节以及报告要求。 本标准不提供测量仰卧位或临床空间测听定位性能的指南。

The methods described in this standard provide data which may be used for assessment of sound localization performance open ear and with head-worn devices using human subjects.The standard describes three measurement methods:1) a low-complexity method using 8 loudspeakers to measure location discrimination performance;2) a more complex, more robust method to measure localization error using 36 loudspeakers; and3) a method to measure the functional impact of degraded localization cues on visual search time with 36 loudspeakers.The standard specifies subject qualification criteria, test space acoustic requirements, details of the three methods, and reporting requirements. The standard does not provide guidance for measuring localization performance for elevation or for clinical spatial audiometry.
