摘要
Abstract
Based on the Statistical Energy Analysis (SEA), cabin noise prediction and control of cruise ships is studied. The main noise sources of the cruise ships, including airdynamic noise and structural noise generated by power equipment such as diesel engines, generators, propellers, air conditioners, fans and so on, are analyzed. Then, the SEA model of the cruise ships is built by using VA One software, and the noises of some important cabins, such as living and entertainment cabins and power equipment cabins, are predicted. The spectrums of noises in those cabins are obtained and compared with the limit value of IMO standard. The calculation results show that those cabins meet the requirements except the four-people living room. It is found that the noise and vibration of the air conditioner room in the upper layer has great influence on the living room by analyzing the main noise sources of the living room. Then, the different floating floors are applied to the air conditioner room to reduce the noise of the living room. Through the comparative analysis the floating floors No. 2 and No. 3 are found to have obvious effect of noise reduction on the living room. Finally, the acoustic characteristics of the floating floor with different thickness of mineral wool are studied and the optimal thickness is found.关键词
