Testing a hydroacoustic radiator in a reverberant tank based on recording the sound field in the air above the tank

A method for calibrating a monopole sound source in a water tank with reflective side walls and bottom is considered. The idea of the method is based on the phenomenon of anomalous transparency of the water-air boundary for a sound source located at a shallow depth. This boundary plays the role of a filter that prevents waves reflected from the side walls and bottom from entering the air. For a shallow source, the field in the air will be approximately the same as for a source located at the same depth in a homogeneous water half-space. This field is described by a well-known analytical formula that makes it possible to estimate the source strength in water based on the sound intensity level measured in air.

On the use of the equivalent source method for free-field calibration of an acoustic radiator in a reverberant tank

It is shown that the use of the equivalent source method allows one to reconstruct the sound field excited by an acoustic radiator in free space from the measurements of the sound filed excited by this radiator in a tank with reflecting boundaries. The key assumption underlying the proposed approach is that the same set of monopoles with the same strengths can reproduce the field of the radiator both in free space and in the tank. The monopole strengths are reconstructed from the measurements in the tank, and the field in free space is then calculated using the known Green function. The feasibility of the approach is demonstrated in a tank experiment.
