飞机减振降噪技术从飞机的初步总体设计阶段时就应当予以考虑,一般最初都会有比较顶层的需求指标,按照这一指标进行飞机的设计与生产,因为减振降噪对于飞机而言不是单个系统的工程。飞机噪声主要包括在起飞和降落阶段对外部环境的噪声辐射和舱内噪声两种类型。对于环境噪声,依据中国民用航空总局CCAR-36 Aircraft vibration and noise reduction technology from the aircraft during the initial design phase should be taken into account, generally initially there will be more top demand indicators, in accordance with this indicator aircraft design and production, because the vibration and noise reduction for the aircraft is not Single system engineering. Aircraft noise mainly includes two types of noise emission and cabin noise on the external environment during the take-off and landing phases. For environmental noise, according to China Civil Aviation Administration CCAR-36
