Abstract
In order to improve the acoustic-vibration environment inside the fairing,the most common and efficient method is laying noise reduction materials on the inner wall of fairing to reduce the sound pressure level of noise.In this paper,the engineering application and research progress of fairing noise reduction materials and applicable frequency bands at home and abroad were summarized.Baseline properties and noise reduction principles of several main noise reduction materials were introduced in detail.On top of all,suggestions for the research and development of noise reduction materials in China were put forward.关键词
