Abstract
Air-conditioning system is a major noise source in ship cabin, and sound-absorption treatment is an efficient way to reduce the cabin noise. In order to examine the effect of sound-absorption on the noise reduction in cabin, the finite element predictive model of noise radiated from the ventilation pipe into the ship cabin was established. Taking the measured sound pressure as the noise source, the effects of sound-absorption of cabin wall and ventilation pipe on the ship cabin noise reduction were investigated, which was used to guide and improve the acoustic design of ship cabin. The cabin noise caused by the improved air-conditioning system was predicted, and the acoustic design for suppression of much higher noise was conducted, a satisfactory solution for reducing the noise level in cabin was obtained.关键词
