Abstract
A radially vibrating, oil filled, cylindrical ceramic transducer devoid
of all forms of pressure release provides a means of transmitting sound
at unlimited depths. A study was made of the admittance characteristics
in the vicinity of resonance of a transducer of this type, which was constructed
with a variable acoustic impedance in the oil filled interior. The
results were compared with theoretical computations, which proved helpful
in analyzing and interpreting the resonances of the transducer. Additional
measurements were made on the transducer and were utilized in the
computation of electroacoustic efficiency at the major resonances. The writer wishes to express his appreciation for the assistance and
encouragement given him in this investigation by Mr. Joe Martin of the
Bendix- Pacific Division of North Hollywood, California.
