Abstract : The patent describes a low frequency broad band hydrophone with orthogonal dipole outputs comprising a mass controlled housing dimensionally much smaller than a wavelength over the desired frequency band and having four piezoelectric elements cantilever-mounted radially to a center mass suspended within the housing. The velocity amplitude of the housing vibration is both independent of frequency and in phase with the acoustic pressures: the detection of said velocity amplitude by said elements provides orthogonal diopole outputs.
