A reverberant water tank has been constructed at the Pennsylvania State University. The background noise, diffusivity of the sound field, and the reverberation time in the tank have been measured as a function of frequency in one-third octave bands, from 80 Hz to 63 kHz. The techniques used to characterize the tank are presented. The characteristics of the tank are compared to other known water tanks. It is demonstrated that the tank is suitable for the experimental determination of the radiation efficiency of a structure by comparing data obtained in this tank with previously presented data for a flat plate.
