扩散场噪声与掠入射噪声的比较与分析

Comparison and Analysis of Diffuse Field Acoustic Noise and Grazing Incidence Acoustic Noise

扩散场噪声与掠入射噪声是噪声试验的两个重要试验程序,主要梳理对比了扩散场噪声与掠入射噪声的要求差异,针对目前存在的问题,提出了噪声试验实施建议,以指导机载产品噪声试验的实施与评价。

Diffuse field acoustic noise and grazing incidence acoustic noise are two important test procedures in acoustic noise test.The different requirements of diffuse field acoustic noise and grazing incidence acoustic noise are mainly combed and compared.In view of the existing problems,some implementation suggestions on acoustic noise test are put forward so as to guide the implementation and evaluation of airborne product noise test.
