声学 声强法测定噪声源的声功率级 第2部分:扫描测量
Application Summary AI generated
This standard specifies a scanning measurement method for determining the sound power levels of noise sources using sound intensity. It is applied in acoustical testing environments, such as laboratories or industrial settings, to measure noise emitted by machinery, equipment, or other sources by scanning a sound intensity probe over a measurement surface. The standard is used for noise control, product compliance, and environmental noise assessment.
