借助声薄弱环节分析的低噪声设计

Low noise design with aid of acoustical weak-analysis

通过减少声的发生、传播和辐射可实现结构噪声控制.降噪措施的设计和实施要求进行详细的声薄弱环节分析,同时应区分是机器的空气声辐射还是固体声辐射.

Structure born noise control could be achieved by reduction of sound generation, transmission loss or reduction of sound radiation. Low noise design and realization of solid-born sound reduction measures needs a detailed acoustical weakanalysis. Here it is necessary to make a distinction between the air-born and the solid-born sound emission of the machinery.
