Sound Power Radiated by Sources in Diffuse Field
Sound power radiated by sources at low frequency notoriously depends on source position. The authors sampled the sound field of a rectangular room at 18 microphone and four source positions. Average power spectra were extrapolated from the reverberant field, taking into account the frequency-dependent reverberation times. They reveal fluctuations that depend on source position and extend far above Schroeder's frequency.:
