In most cases, while the sound power level of machines and devices is determined, it is assumed that tested objects are sound sources which can fit in a so-called reference box. Such an approach takes into account the influence of local sources. Although it does not allow their localization, separate noise measurement and evaluation. There are devices which have two or more relevant sound sources. In this paper this type of devices has been defined as devices with extensive sound sources (DESS). The tested device is a functional unit but its local sound sources are distant from each other. The results showed that determining the sound power level only is not sufficient for proper parameterization of noise emitted by DESS.
