In order to study the noise control technology of luxury cruise, it is necessary to conduct a comprehensive analysis and research on the vibration and noise sources of luxury cruise. This article takes the noise source of the main laundry room of a luxury cruise as an example, and uses the scanning sound intensity method to measure the sound power. The sound power of the equipment is used as the input of statistical energy analysis to predict the noise of the luxury cruise laundry and its adjacent cabins, evaluate the influence of noise sources on the cabin noise level, and study the control effect of the cruise ship interior materials. The results show that the noise source of the luxury cruise laundry room has a great influence on the main laundry, and the typical interior materials of luxury cruise can significantly reduce the noise of the laundry, which can provide reference for the measurement and analysis of the steady-state noise source of the luxury cruise.
