Experimental progress of noise measurements in reverberation tanks

Abstract

The methods and means for measuring the radiation characteristics of underwater sound sources have been developed under the conditions of reverberant tanks. From the perspective of experimental research, this paper introduces the methods of measuring the radiated sound power of steady-state sound sources and transient sound sources in reverberation tanks. The experimental subjects include the typical transducer under steady-state excitation, the cylindrical shell under steady-state excitation, the transient CW pulse sound signal and the underwater transient spark sound. The measurement principles, experimental system and measurement accuracy involved in each experiment are also listed. The experimental results show that the reverberation tank is an effective experimental device for measuring the acoustic characteristics of underwater sound sources, which has the advantages of simple experimental conditions, high measurement efficiency and strong tolerance for different types of sound sources.The methods and means for measuring the radiation characteristics of underwater sound sources have been developed under the conditions of reverberant tanks.
