摘要
本文通过对Y-12飞机舱内声强测量与分析,初步识别出该型飞机的主要噪声源及其向舱内传播途径,并提出了可行的降噪措施.
The main noise source and its propagation path to the aircraft cabin have been identified initialy by use of the sound intensity measurement and analysis inside Y12 aircraft in this paper. The effective noise-reduced methods have been provided.
