It can be shown that as a result of the natural life cycle of a hydrophone sensor unit, there can be rather large frequency dependent variations that exceed 12 dB in sensitivity and 60° in phase for the “outof- specifications” sensors, especially near and below 10 Hz. In most cases, the effects of these life cycle variations can be characterized by a resonance frequency and damping. In order to match geophone responses more closely, second order, digital, equalization filters have been designed and applied that shift each sensor's resonance to be well within nominal specifications. When all of the hydrophones responses have been equalized in amplitude and phase, then channel-to-channel consistent amplitudeonly corrections can compensate for differences between the intrinsic sensitivities of sensors to pressure (V/bar transductance), which is not determinable from electrical measurements only.
