Abstract

Real ship tests were conducted to study transmission characteristics of underwater radiated noise caused by cabin air noise excitation.A real ship test method for underwater radiated noise caused by cabin air noise excitation was established with the simulated sound source excitation method.Based on a single input/output model and transfer function, the analysis method for transfer characteristics from air noise to underwater radiated noise was established.Real ship sound source excitation tests were conducted to acquire time histories of air noise and underwater radiated noise as well as the transfer function from air noise to underwater radiated noise, analyze feature laws and transmission characteristics of underwater radiated noise caused by air noise excitation, and verify the feasibility and validity of the real ship transfer characteristics test and analysis method.Results showed that there is a linear relationship between cabin air noise and underwater radiated noise; their transfer relationship presents characteristics of a linear system related to frequency; the overall change trend of the transfer function from air noise to underwater radiated noise within the frequency range of 50 Hz-5 kHz has a feature law of first increase and then decrease.
