摘要
对不同扬声器张角的串音消除重放系统对头部偏离理想听音位置时的重放性能进行了客观评价。定义了反映系统在头部偏离理想位置时的重放性能稳定性的误差参数,并利用高方向分辨率的HRTF函数对误差参数进行计算,从而得到不同扬声器张角重放系统的性能比较及其与频率的关系。分析计算结果表明,8°-16°张角的重放系统对头部位置偏离具有较好的稳定性,尤其在约500Hz至7kHz的频率范围效果较为显著。
The performances of cross-talk cancellation systems with different listening angles were objectively evaluated with respect to head movements.The error parameters were defined and calculated with high directional resolution HRTFs to compare the performance and to reveal the frequency dependencies of the performance of the different listening angles.The calculation results show that the systems with listening angles between 8° to 16° are more robust to misalignment of head position especially at the frequencies range of 500Hz-7kHz.
