概要

論文の詳細を見る
This paper provides a summary of cabin atmosphere circulation and acoustic noise control of Japanese Experiment Module (JEM). The JEM has some fans to maintain atmosphere circulation in its cabin and ventilate the air with adjacent module. On the other hand, these fans are identified as significant acoustic noise sources. It is needed to reduce in-duct noise from these fans to control cabin acoustic noise environment. Silencers have been developed for each fan and the in-duct noise contribution to cabin noise level would be sufficient small.
