Abstract :
The range capability of underwater acoustic equipment installed onboard underwater vehicles is limited by the noise generated by propellers, hydraulic pumps.... Measuring this noise at sea is quite expensive. Here is described a procedure allowing the measurement of the radiated noise in test tanks. This method is derived from techniques previously developed in aerial acoustics and in electromagnetism.
