A balanced sonar transducer comprising a front radiating mass and a rear mass coupled thereto via a ceramic transducer element which imparts vibrational motion to the front and the rear masses. The front and the rear masses are secured to a bulkhead via a tie rod which passes through the rear mass and the transducer element and is secured in the front mass. A disc spring is placed between the bulkhead and the rear mass and has a compliance of a suitable magnitude to resonate with the rear mass at a frequency which approximates the resonant frequency of the front mass with the compliance of the tie rod. The approximate matching of the resonant frequencies provides for a balancing of the stresses applied to the transducer element which insulates the transducer element from a vibrational acceleration imparted to the transducer assembly by vibrations of the ship and of the bulkhead to which the transducer assembly is affixed.
