NOTE: All sound testing is performed in accordance with ISO 9614-2 Determination of Sound Power Levels. ISO 9614-2 specifies a method for measuring the component of sound intensity that is normal to a measurement surface. The measurement surface is chosen to enclose the noise source(s) so that the sound power level can be determined.
