A method for determining whether a hydrophone being tested is being properly responding to a pressure field is described. The method comprises the steps of providing a shell filled with a liquid and having impedance heads attached to a first end and a second end of the shell and a number of pressure sensors or hydrophones positioned between the first and second ends within the liquid filled shell developing a model of the pressure field within the liquid-filled shell and comparing the response of at least one of the pressure sensors to the pressure field described by the model. The model of developing the step involves modeling the extensional wave contribution and the breathing wave contribution in the pressure field.
