An experiment performed in deep water near San Clemente Island, California, showed that discrete scatterers were the primary source of acoustic volume reverberation at the test site. Scatterers reflected the incident waveform without apparent distortion. Estimates of the scatterer density and scatterer reflectivity distribution were obtained from experimental data, but the estimates were distorted by the transducer beam pattern and by overlapping echoes. Analysis of the reverberation envelope showed that reverberation was homogeneous in the horizontal plane and that the reverberation envelope amplitude was not Rayleigh distributed. A computer was programmed to simulate volume reverberation according to a discrete scattering model developed by Faure, Ol'shevskii, and Middleton. The scatterer density and reflectivity estimated from experimental data were changed until simulated and measured reverberation envelopes were statistically alike. When simulated and measured envelopes were alike, improved estimates of scatterer density and scatterer reflectivity were obtained from the simulation. The scatterer density which gave best agreement between simulated and measured envelopes was 0.0010 scatterers per cubic foot. The scatterer reflectivity was approximately exponentially distributed.
