Acoustics. Determination of sound power levels of noise sources using sound intensity - Precision method for measurement by scanning has-hardcopy proof stress1 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 sound source(s) of which the sound power level is to be determined. Surface integration of the intensity component normal to the measurement surface is approximated by subdividing the measurement surface into contiguous partial surfaces, and scanning the intensity probe over each
