ITC Hydraphones & Underwater Acoustic Transducers

Application Information

Military Applications:

Underwater acoustic transducers are an important part of many naval sonar systems. Applications include: Anti-Submarine Warfare where submarine detection is done using hydrophone arrays. Torpedo countermeasures where acoustic signals steer homing torpedos away from their targets. Mine hunting sonar systems with high frequency transducers to detect mines or small objects. Communication links such as underwater telephones where two way transducers are used to communicate between surface ships and submarines.

Commercial Applications:

Oceanographic research establishments and the offshore oil industry employ underwater transducers for a variety of applications: Sub-bottom profiler transducers penetrate ocean or river bottoms to study sea bed composition. Side-scan sonars map the sea bed act as 'Side-wise' sonar for ship tracking. Acoustic speedometers where paired transducers point down to obtain ship speed from doppler shift of bottom return signals.

Transducer beacons and transponders transmit sound at continuous or regulated intervals to provide tracking and positioning information. Transducers are also employed for telemetry purposes where a sound beam is used instead of a wire link for transmitting information.

The commercial fishing industry uses a variety of transducers including: Forward looking active transducers for spotting schools of fish. Dual and split beam transducers perform counting in fish population studies. Detecting the sound intensity of rain on a water surface. Emulating the mating vocalizations of marine mammals.
