请教:帮助里的这段话应该怎么理解??
Spherical wave source那章:就是那个球声源的幅值A,英文帮助说是: A is the pressure amplitude(peak,not rms)
one unit distance(eg one metre)away from the source.
请问:这个A到底应该取多少呢??
如果声源的声压是0.04pa,那是不就按0.04pa算呢?? 就是填的0.04pa A is the pressure amplitude(peak,not rms)
one unit distance(eg one metre)away from the source.
意思是 从源开始的 单位长度上的声压幅值。
