Preliminary Model Analysis of Acoustic Noise Levels for Space Station

Abstract:

This paper presents the modeling and analysis method of acoustic noise levels of whole audible frequency range for Chinese Space Station (CSS) module. Using Boundary Element Modeling (BEM), the acoustic analysis model of low frequency range for CSS module was established. The analysis model of high frequency range was created by using Statistical Energy Analysis (SEA) method. Based on the established models, the acoustic noise levels in all areas of CSS module were analyzed and the results for some typical areas are provided. Finally, the acoustic contribution of noise sources according to their spectral characteristics is analyzed and the implementation of noise control methods to reduce acoustic levels in CSS module is discussed.
