Scope: This standard specifies the on-site measurement method for the sound power level of sound sources, especially non-moving sound sources. This standard uses the comparative method, and all measurements use octave bands. This standard can be used in various test environments other than those required by all laboratory measurement methods, as long as the background noise of the environment is sufficiently low and the sound pressure level at the position of the microphone depends mainly on the reflection of the room surface. This standard is mainly applicable to noise sources where radiated noise is a broadband noise source. It is also applicable to noise sources that radiate narrowband or discrete pure tones, but the measurement uncertainty may be larger than that given in this standard.
