Acoustics—Determination of sound power levels and sound energy levels of noise sources using sound pressure—Survey method using an enveloping measurement surface over a reflecting plane
IDT ISO 3746:2010
全国声学标准化技术委员会(SAC/TC 17)
本标准规定了在满足给定条件的测试环境中,根据包围噪声源(机械或设备)表面上测得的声压级来确定噪声源声功率级或声能量级的方法。利用这些测量可计算出噪声源所产生的A计权声功率级(或猝发声和瞬态噪声的A计权声能量级)
