Virtual walking path in response to spatially separated target signal and masker presented at equal intensity

The target signal was presented at 76 dB SPL from a forward speaker while the masker was presented at the same intensity from a lateral speaker to the right. ‘X’ and ‘Y’ coordinates of virtual walking paths measured from the trackball system. Data plotted in figure 5E.目标信号由前置扬声器以76分贝声压级（dB SPL）呈现，与此同时掩蔽信号由右侧侧向扬声器以相同声压级播放。虚拟行走路径的X、Y坐标由轨迹球系统（trackball system）测得。相关数据已绘制于图5E中。
