Scope

This standard specifies the measurement method for sound pressure levels on the surface of noise sources (machines or equipment) in anechoic chambers and semi-anechoic chambers. Using these measurement methods, the 1/3 octave band or A-weighted sound power level of the noise source (as well as the sound energy level in the case of pulse or transient noise radiation) can be calculated, including corrections for differences between the meteorological conditions at the measurement time and location and the reference meteorological conditions corresponding to the reference characteristic sound impedance.
Generally, the measurement frequency range is a 1/3 octave band with a center frequency of 100 Hz to 10,000 Hz. If necessary, the frequency range can be expanded or reduced, and the test chamber should meet the requirements for these frequencies.
