All components in the receive path (from the hydrophone onward) are... WebThe main part of a hydrophone is it's transducer. The transducer converts sound waves or the mechanical sound energy into minute electrical energy that can then be amplified. In …
The first hydrophones consisted of a tube with a thin membrane covering the submerged end and the observer's ear on the other end. The design of effective hydrophones must take into account the acoustic resistance of water, which is 3750 times that of air; hence the pressure exerted by a wave of the same intensity in air is increased by a factor of 3750 in water. The American Submari…
