Abstract
Certain implementations of the disclosed technology may include systems and methods for dynamic pressure testing of transducers in communication with a liquid. A method is provided that can include dynamically pressurizing a liquid in a cavity associated with a housing. While dynamically pressurizing the liquid, the method includes simultaneously measuring: a change in volume of the liquid; a test frequency response, by a test transducer in communication with the liquid; and a reference frequency response, by a reference transducer in communication with the liquid. The method may further determine a normalized frequency response of the test transducer, based at least in part on the test frequency response and the reference frequency response. The method may further provide an indication of the normalized frequency response of the test transducer and an indication of the bulk modulus of the liquid.
