摘　　要：为得到不同拾音制式在空间感塑造上的差别,对5种常用的环绕声拾音方法进行主观评价实验,得到各拾音方法在5个空间特性参量上主观心理尺度值,总结出拾音制式中传声器布放对空间特性的影响规律。运用环绕声录音和重放原理,结合对重放声双耳互相关系数测量的数据,对结论进行了分析和讨论。A listening test is designed to find the difference of spatial attributes between five surround microphone techniques. The values of the five recording techniques on psychologic scale of different spatial attributes are drawn by the listening test. With the result, the relationships between microphone placement and spatial attributes are also concluded. Meanwhile, with the measurement result of the IACC（Interaural Cross-correlation Coefficient）, further discussion and analysis are also conducted.
