声学 声强法测定噪声源的声功率级 第1部分:离散点上的测量
Application Summary AI generated
This standard specifies a method for determining the sound power level of a noise source by measuring sound intensity at discrete points on a measurement surface. It is applied in acoustical testing environments, such as laboratories or industrial settings, to quantify noise emissions from machinery, equipment, or other sources, particularly when background noise or reverberation conditions make traditional sound pressure methods unreliable.
