ABSTRACT:
A dipole hydrophone transducer which includes first and second magnetostrictive arms and associated windings. One arm includes a radiation target for acoustic energy for production of proportional signals in the windings and the other arm includes a counterbalancing mass for acceleration cancelling. In one embodiment the radiation target is in the form of a disk and the counterbalancing mass is in the form of a ring surrounding the disk so that the disk and ring have the same center of gravity.
