摘　　要：以环绕声前方三声道全指向阵列系统为对象,研究声源入射角度与重放声像定位之间的关系。在对理想状态下的阵列系统做出分析的基础上,阐述声道间的串音、声源到传声器之间强度差、频率等因素如何使声像发生畸变。进而讨论为避免声像畸变,如何在实际录音过程中对传声器阵列系统进行调整。Surround three - channel omni - directional microphone array system is object in this paper, researched about the relationship between the sound source incident angle and the playback sound image localization. Based on array system for under ideal condition, consider effect of sound image localization on the erosstalk between channels, the intensity difference between the sound source to array system and frequency. Make analysis these factors how to cause the image distortion. Further, in order to avoid image distortion, discuss how to adjust the microphone array system in the process of recording.
