峰值（Peak）是信号达到的最大电平，对于正弦波来说，峰值电平大于有效值电平3dB，对于音乐信号来说，峰值电平超过有效值可达10-15dB在评定一种扬声器的位移能力时，峰值是重要的，峰值因子，用来说明峰值电平与有效值电平的比率，对于按AES2-1984的粉红色噪声源来说，峰值因子为6dB，即峰值电压是有效值电压的4倍。（节录自：音响初级知识）
Calculate Now将依据你所选择的波形的最大振幅和在它右边Peak Level（峰值电平）里所希望到达的振幅的预设值停止计算，从而自动将音量（振幅）添加到您所希望的值。

因为通常电声设备技术指标给出的是噪声准平均值电平，而不是噪声准峰值电平，这一点应加以注意。
Because normally the electro-acoustic equipment, technical specifications are given quasi-average noise level, rather than quasi-peak noise level, this should be noted.
显见，动态阈是用准峰值电平表示，而信噪比则是用准平均值电平表示的，两者的区别是显而易见的了。
Obviously, the dynamic threshold is to use quasi-peak level that, while the signal to noise ratio is expressed with the quasi-average levels, and the difference is obvious in.
与传统的峰值一半电平触发方式相比，能够显著提高测试精度，从而扩大了光幕靶的使用范围。
Compared with half peak voltage level trigger manner, the measurement accuracy is improved significantly and the application field of digital optical screen is expanded.
