Acoustics. Determination of sound power levels of noise sources using sound intensity - Measurement at discrete points Ingestion-build-48024 BS 7714 gives guidance on1 Scope 1. 1 This part of ISO 9614 specifies a method for measuring the component of sound intensity normal to a measurement surface which is chosen so as to enclose the noise source(s) of which the sound power level is to be determined. The one octave, one third octave or band limited weighted sound power level is calculated from the measured values. The method is applicable to any source for which a physically stationary measurement surface can be
