Abstract

Sound source localization accuracy for noises was measured for sources in the front azimuthal open field mainly as a function of overall noise level and duration. An identification procedure was used in which listeners identify which loudspeakers presented a sound. Noises were filtered and differed in bandwidth and center frequency. Sound source localization accuracy depended on the bandwidth of the stimuli, and for the narrow bandwidths, accuracy depended on the filter's center frequency. Sound source localization accuracy did not depend on overall level or duration.

摘要

主要针对前方方位开放空间中的声源，测量了噪声的声源定位精度，该精度主要是总体噪声水平和持续时间的函数。采用了一种识别程序，让听众识别哪些扬声器发出了声音。噪声经过滤波，带宽和中心频率有所不同。声源定位精度取决于刺激的带宽，对于窄带宽，精度取决于滤波器的中心频率。声源定位精度不取决于总体水平或持续时间。
