Integrating the sound intensity vector on the area which surrounds a sound source gets the sound power of this sound source. Since the integral of the sound power of the sound sources which are not enclosed by the area is zero, one could measure the sound power in ordinary environments correctly by measuring sound intensity.

对于一个声源，只要将其包络面上的声强矢量作积分，就可以求出被围声源的声功率，而测量区域之外的干扰噪声得以抵消，因此可以在普通环境下能准确地测定声源声功率。
