With today's wide-frequency-range, extreme-dynamic-range stereo sound tracks it is appropriate to consider hydrophone techniques that can bring underwater sound pickup to the same state of the art that airborn sound pickup enjoys.
Underwater sounds can be captured as accurately and easily as milking an orchestra on stage; in some cases more easily, since there is always something to hang the. Abstract.
All the applications of underwater projectors described at the beginning of Chapter 3 also require the use of hydrophones. In most active sonar systems the same transducers serve as both projectors and hydrophones, but there are good reasons in some cases to use separate hydrophones for reception, (e.g., hydrophones in towed line arrays can be well removed from the ship’s self-noise).Cited by: 4.
In this work, active vibration control of an underwater cylindrical shell structure was investigated, to suppress structural vibration and structure-borne noise in water.
Finite element modeling of the submerged cylindrical shell structure was developed, and experimentally evaluated. Modal reduction was conducted to obtain the reduced system equation for the active feedback control algorithm Cited by: Sep 02, · Abstract.

The response of a cylindrical end-capped hydrophone (NUWC-USRD Model H56) used for calibration purposes is shown in Fig. It has FFVS of − dB re 1 µPa.
The new edition of the book is extended in some chapters, translated to English and divided into two separate volumes – the first one with the physical foundations of piezoelectric sensorics, the second one mostly applicationoriented piezoelectric sensorics instrumentation.
