Specifies a method for measuring the component of sound intensity normal to a measurement surface which is chosen so as to enclose the noise sources of which the sound power level is to be determined. Coverage includes acoustic environment, instrumentation, calculation of sound power level, and information to be reported. Also gives definitions, tables, diagrams and annexes.
