Abstract
A broadband low frequency source suitable for deep sea applications without pressure compensation is disclosed. The source utilizes hydraulically powered flexural disc radiators which are sized to small fractions of the generated wavelength. Inertance is applied hydraulically to the radiators to effectively mass load the radiators, thus lowering the resonant frequency of the radiators to fall within the transmission band to minimize driving power requirements and provide for operation over a wide bandwidth.
