Abstract
The principles and limitations of determining the radiated acoustic power of sources of sound in reverberation chambers and in anechoic rooms are reasonably well understood. By necessity, the practicing acoustician must frequently carry out sound power determinations in ordinary spaces such as factory or office areas. The limitations governing sound power measurements in such semireverberant spaces [R. J. Wells, Power App. and Systems No. 21 (1955)] are less well understood at present. To obtain a better estimate of the accuracies obtainable in practice in such spaces the results of a series of sound power determinations on two small sound sources in several semireverberant spaces are presented and compared with the results obtained outdoors. One of the sound sources is in the process of being tested at other laboratories for further cross comparison.
