Acoustics. Determination of sound power levels and sound energy levels of noise sources using sound pressure. Engineering methods for an essentially free field over a reflecting planeWhat is BS EN ISO 3744: 2010? BS EN ISO 3744: 2010 gives best practice recommendations for acoustic measurement. This includes determining the sound intensity of a noise source from sound pressure levels that are measured on a surface surrounding the machinery or production equipment. This relates to an environment where an acoustic free field is near one or more reflecting planes. The sound intensity or sound energy level in frequency bands or with A
