摘要
借助声学头模对不同声源位置条件下的双耳录音信号进行了主、客观分析，结果显示噪声源在头模两侧30°～60°范围内对人耳的干扰最强；语声源对信噪比作用较小，而噪声源对信噪比的影响明显；听感清晰度随声源相对方位角的增大而增大；当语声源和噪声源之间的相对方位角固定时，听感清晰度与双耳信号的信噪比较大值呈显著相关。
In this paper,acoustic dummy-head to analysis the binaural recording signals under different conditions in both subjective and objective way are used. The results show that the noise source cause the strongest interference when located at 30°～60° range around head. Voice source signal play a smaller role in SNR, while the influence of the noise sources on SNR is significantly. Hearing intelligibility is increasing from the relative azimuth between voice and noise. Hearing intelligibility is significantly correlated with binaural SNR when the azimuth between voice and noise sources is fixed.
