摘要： 分析船舶噪声与振动源，讨论船舶结构噪声源和空气噪声源的传播路径，介绍船舶噪声与振动控制的规范标准，并对船舶噪声与振动控制方法作较详细的论述，通过应用基于统计能量法的全频域噪声分析软件VA ONE，对某散货船艉部进行噪声分析计算，得到船舶噪声与振动的响应特性。经过与海试现场采得数据比较，发现计算论证的趋势和实际是相符的。

Abstract: The vibration and noise sources and their diffusing routes of ships are described and analyzed. The standard and method for control of noise and vibration of ships are introduced. The noise level of ship’s AFT is analyzed by VA ONE, and the result of noise and vibration are obtained by means of statistical energy analysis (SEA). It is found that the results are in good agreement with the measurement data in shake-down voyage.

Key words: vibration and wave, vibration(noise) standard, structure-borne sound, statistical energy analysis (SEA), vibration(noise) evaluation
