This report contains descriptions of the two phases of the sound power measurements project of the BCR programme. In the first phase the sound power of four reference sound sources in different environments was determined. In the second phase two reference sound sources were selected and the measurements in the hemi-free field environment were extended to include two different orientations of microphone and two distances between the source and the microphone. The main results of both studies are presented and the analyses of the results of the participating laboratories are included.
