DIN EN ISO 3744:2011 PDF

Scope: This International Standard specifies methods for determining the sound power level or sound energy level of a noise source from sound pressure levels measured on a surface enveloping the noise source(machinery or equipment) in an environment that approximates to an acoustic free field near one or more reflecting planes.
