A state-of-the-art assessment of mobility measurement techniques—results for the mid-range structures (30–3000 Hz)

During the period 1979–80, a survey was conducted in Europe to assess the state-of-the-art of structural mobility measurement technology. The results from this exercise—a selection of which are presented here—indicated a considerable degree of inconsistency and highlighted the need for more careful measurement practice and for greater use of checks on measured data.
