Summary:

This paper presents the key issues regarding the measurement of damper (shock absorber) noises, including the type of microphones, the locations of microphones, the mini-anechoic chamber design considerations, selection of a shaker, and the observations gathered from conducting damper noise measurements in the Monroe Auto Equipment Company. The characteristics of two typical noises, a mechanical/click noise and a swish noise, generated by the dampers are discussed in detail. In addition, the functional features of a complete digital signal processing system, including A/D (analog-to-digital) and D/A (digital-to-analog) converters for the damper's noise and vibration measurements, are discussed in the paper
