【Abstract】 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.更多还原
