Virtual walking path in response to spatially grouped target signal and maskers presented at equal intensity.

The target signal was presented at 76 dB SPL from a forward speaker while two coherent maskers were presented at the same combined intensity from adjacent speakers to the left and right of the signal speaker. ‘X’ and ‘Y’ coordinates of virtual walking paths measured from the trackball system. Data plotted in figure 5D.

目标信号由前置扬声器以76分贝声压级（dB SPL）播放；与此同时，位于信号扬声器左右两侧的相邻扬声器以相同的总合成声强，播放两路相干掩蔽声（coherent maskers）。
虚拟行走路径的X、Y坐标由轨迹球系统（trackball system）测得。
