alibration, Metrology, and Traceability of Shock and Vibration Transducers

Vibration measurements of acceleration, velocity, and displacement can be classified in two main ways: (i) relative measurements made between two points with systems such as laser Doppler interferometers and (ii) absolute measurements made with seismic mass transducers (mainly accelerometers). The calibration of transducers used for both types of measurement is described in detail in Ref. [18]. Reference [18] also describes the traceability of vibration measurements and Ref. [19] describes the traceability of shock and vibration measurements to national and international standards in more detail. In many ways the traceability requirements and calibration concerns for shock and vibration transducers are similar to those of microphones.
