GB/T 16538-1996 Acoustics--Determination of sound power levels of noise sources using sound pressure--Survey method using a reference sound source (English Version)
This standard specifies a simple method for measuring sound power level A of sound sources (including equipment, machines, components or parts) using standard sound sources. Measure the sound pressure level produced by the measured sound source and the standard sound source at the specified measuring point, and the sound power level of the measured sound source is obtained from the measured sound pressure level after environmental correction. The environmental correction is obtained by calculating the calibration value of the sound power level of the standard sound source and the measured sound pressure level. The location and number of microphones and standard sound sources are determined by the size of the measured sound source, the size, number and orientation of the reflection surface near the sound source and other acoustic conditions. This standard is a supplementary method to the national standard GB/T 3768.
