"Yokosuka" is equipped with underwater acoustic systems for measuring the Submergible position and communicating with the Submergible. Therefore maximum permissible noise level of "Yokosuka" radiation acoustic noise was set at the planning stage. We estimated the radiation acoustic noise level and applied noise reduction technique to main engines, many pumps and ship structures to build a low noise ship. On "Yokosuka" sea trial, we were certain that the radiation acoustic noise level was lower than the maximum permissible level and there was no bad noise source for underwater acoustic systems. This paper presents the result of underwater acoustic intensity on "Yokosuka" sea trial.
