Simple a priori selection of sound power measurement standards

S.E. Keith

Abstract


Various aspects of the Canadian CSA Standard on sound power measurement are discussed. There are over 10 basic ISO standards for measurement of sound power and 5 standards for measurement of emission sound pressure. The reverberant room standard, ISO3743-1 requires the room volume to be atleast 40 times the volume of the source and α must be less than 0.2. It is observed that in intensity measurements the allowable background noise is limited by the dynamic capability of the measuring equipment.
