ActiveAcoustics—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
声学 声压法测定噪声源声功率级和声能量级 采用反射面上方包络测量面的简易法
Application Summary AI generated
This standard specifies a simplified survey method for determining the sound power and sound energy levels of noise sources by measuring sound pressure levels on an enveloping surface over a reflecting plane. It is applied in industrial and environmental acoustics testing for machinery, equipment, and appliances where a quick, cost-effective noise assessment is needed without requiring a specialized acoustic environment. The method is commonly used for product noise labeling, quality control, and regulatory compliance in manufacturing and consumer goods sectors.
