噪声源物理模型及抑制机理探讨

Exploration of the physical model of noise source and its restrictive mechanism

用物理模型的方法,分析机械噪声的声源、能量、声压与所对应的机械运动各参数之间的关系,为控制和改善机械噪声提出一点理论依据和抑制机理。

By use of the method of analyzing physical model,this paper explores the relationship between the sound source,sound energy,sound pressure and the parameters of mechanical movement,puts forward the theoretic foundation for restraining and improving mechanical noise.
