Signal amplitude in a Chorus

The sound recording of the central microphone in small choruses consisting of four males was evaluated using a Spike2 macro. The rms and maximum amplitude values of either solo singing males and signals produced by four males simultaneously are shown in this table. Data is shown in Fig. 4B针对由四名男性组成的小型合唱中中央麦克风采集的录音，本研究采用Spike2宏程序进行分析评估。本表列出了独唱男性个体以及四名男性同时发声时产生的信号的均方根（root mean square, RMS）与最大振幅值。相关数据已在图4B中展示。
