摘　　要：文中基于声振分析软件VA one软件,利用统计能量分析法对整艘客船的高频舱室噪声水平进行预报分析及评估.对不符合噪声标准的舱室,分析其噪声能量的主要输入源.将声学包针对性地布置在舱室噪声主要输入源上,使噪声水平降至预期的效果,节约了大量布置时间和成本.Based on the acoustic vibration analysis software VA one,statistical energy analysis method was used to forecast,analyze and evaluate the high frequency cabin noise level of the whole passenger ship.The main input sources of noise energy for cabins that do not meet noise standards were analyzed.The acoustic package was arranged on the main input source of cabin noise,which reduces the noise level to the expected effect and saves a lot of arrangement time and cost.

关 键 词：舱室噪声 统计能量分析法 VA one 声学包 噪声控制
