Acoustics. Determination of sound power levels and sound energy levels of noise sources using sound pressure. Engineering methods for small movable sources in reverberant fields - Comparison method for a hard-walled test room Ingestion-build-96603 BS EN IEC 61000 is1 Scope 1. 1 General This part of ISO 3743 specifies methods for determining the sound power level or sound energy level of a noise source by comparing measured sound pressure levels emitted by this source (machinery or equipment) mounted in a hard walled test room, the characteristics of which are specified, with those from a calibrated reference sound source. The sound power level (or, in the case of noise bursts or transient noise emission, the
