豪华邮船洗衣房噪声源测量与舱室噪声分析

为研究豪华邮船噪声控制技术,需对豪华邮船振动噪声源进行全面的分析。以豪华邮船主洗衣房噪声源为例,使用扫描声强法确定其声功率,将设备声功率作为统计能量分析的输入,预报豪华邮船洗衣房及其相邻舱室的噪声,评估洗衣房噪声源对舱室噪声水平的影响程度,同时研究邮船内装材料对洗衣房噪声的控制作用。豪华邮船洗衣房噪声源对主洗衣房影响较大,且典型邮船内装材料可显著降低洗衣房舱室噪声。上述研究内容可为后续豪华邮船各类处所稳态噪声源的测量分析提供参考。

Noise Source Measurement and Cabin Noise Analysis of Laundry in Luxury Cruise Ship

In order to study the noise control technology of luxury cruise ship, the vibration noise source of luxury cruise ship should be analyzed comprehensively. Taken the noise source of main laundry in luxury cruise ship for example, the scanning sound intensity method is used to determine its sound power, the equipment sound power is used as the input of statistical energy analysis, the noise of laundry and its adjacent cabins in luxury cruise ship is forecasted, the influence of laundry noise source on cabin noise level is evaluated, and at the same time the control effect of interior decoration material in cruise ship on laundry noise is studied. The noise source of laundry in luxury cruise ship is of a great influence on the main laundry, and the typical interior decoration material in cruise ship can significantly reduce the laundry noise. The above research can provide reference for the subsequent measurement and analysis of steady noise source of all kinds of space in luxury cruise ship.
