在距离约50厘米(0.5米)的时间延迟为一个信号，达到第一位，然后在其他麦克风从侧面大约是1.5毫秒(1到2毫秒)。
At a distance of about 50 cm (0.5 m) the time delay for a signal reaching first one and then the other microphone from the side is approximately 1.5 msec (1 to 2 msec).
如果你增加它们之间的距离麦克风，你有效地降低皮卡角。
If you increase the distance between the microphones you effectively decrease the pickup Angle.
