拍 由两个频率相接近的声音合成的一个低频变幅的声音。常见的拍现象有:钟声明显的忽强忽弱变化和发电机开动时的磁铁哼嗡声等。在受迫振动中,当激励函数频率与振动系统频率接近时,也可观察到拍的现象。此现象可用图 1的两个简谐振动(见线性振动)的合成来说明。 用方程x1=asinωt和x2=bsin(ω+Δω)t表示图1的两个简谐振动,则合成后的振动方程为: 此拍的振幅是,它以Δω频率在(a+b)和(a-b)之间变化(图2)。拍频率(简称拍频) 是指每秒钟内振幅从一个最小值通过最大值再到下一个最小值的次数。图中所示的是a=b时拍的图形。 光学中的干涉现象和无线电中的外差法也可以用沿同一直线上的简谐振动的合成来说明。
