ELECTROACOUSTIC PROPERTIES OF MYLAR DIELECTRIC UNDERWATER SOUND TRANSDUCERS.
NAVAL POSTGRADUATE SCHOOL MONTEREY CA
The operation of the electrostatic transducer with mylar dielectric as a transmitter and receiver of underwater sound is studied theoretically and experimentally. Transfer functions based on equivalent circuits which enable transmitter and receiver sensitivities to be determined by a computer program are formulated. The values of the transducer parameters are theoretically postulated and then experimentally verified. The transfer functions are experimentally verified by source level measurements and reciprocity calibrations. It is shown that a transmitter-receiver combination acts as a frequency independent input-output device over a wide bandwidth. Author
