This patt of ISO 3743 specifies a relatively simple engineering
method for determining the Sound power levels of small, movable noise sources. The measurements are carried out when the Source is installed in a hard-walled test room. A comparison method is used to determine to the octave-band Sound power levels of the Source. The spatial average (octave-band) Sound pressure levels produced by the
Source under test are compared to the spatial average (octave-band) Sound pressure levels produced by a reference Sound Source of known Sound power output. The differente in Sound pressure levels is equal
to the differente in Sound power Ievels if conditions are the same for both sets of measurements. The A-weighted Sound power Ievel is then calculated from the octave-band Sound power Ievels.
