WebJan 1, 2016 · Geophones are capable of measuring velocity linearly over a broad frequency range (Barzilai et al. (1998a)). At low frequen- cies they are limited by their natural frequency where the sensitivity drops with 40 dB/dec (Zou et al. (2010)). There are several approaches reported to improve the performance of a geophone. WebBroadband velocimeters have a larger passband than geophones and can measure ground motions with frequencies ranging from 0.001 to 500 Hz. Classical short-period velocimeters are constituted by three orthogonally mounted geophones that have natural frequencies of a few hertz. ...
