Air - and Structure - Borne Noise Reduction of Automotive Dampers 951256

The characteristics of automotive dampers (i.e. shock absorbers) noise are discussed in detail from both aspects of mechanical vibration and fluid flow induced noises. The measurements based upon industrial specifications of structure- and air-borne noises of automobile dampers are presented. Several noise reduction attempts were conducted on double-tube dampers at Monroe Auto Equipment Company. The results of these typical modifications and their physical implications are included in the paper.
