||The results are presented of round robin tests conducted by 14 German laboratories experienced in noise measurements. The laboratories measured the sound power levels of 3 different noise sources in open air, in anechoic and semi-anechoic chambers and in various types of ordinary rooms. The measurements were performed in 29 different environments according to standard ISO 3744. The purpose of the measurements was to check the standard deviations mentioned in the standard and to determine sources of errors. Recommendations for improvement of the ISO standard are presented.
