Abstract

The pure-tone, narrow-band, and 13-oct band probability distribution functions of the SPL for source positions (located on the floor) and receiver positions (located in the interior away from boundaries) were investigated for a random dipole source (Ilg Reference Sound Source), a dipole source (unbaffled loudspeaker), and a monopole source (loudspeaker) for frequencies from 100 to 4000 Hz. The experimental data indicate that an experiment in a reverberant room must be carefully defined. A theoretical model is advanced to explain the observed results.
