http://www.teledynemarine.com/reson 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 Subma…
WebThe US sonars operated at frequencies of 24-30 kHz, above the frequency range of human hearing, which reduced intercept detection. They were also above the fre-quencies of most shipboard machinery noise sources as well as above the range of most wind driven sea-surface noise. These sonars worked by transmitting a short tone burst or
