Simple Piezoelectric Accelerometer Geophones for Geophysical Laboratory Investigations
Seismo-acoustic work has become firmly established in contemporary experimental geophysics. It is done largely in the laboratory, e. g., by testing rock specimens or standard materials in presses or under dynamic loading (impact or explosive). As no suitable equipment (in particular, geophones for laboratory use) is made commercially, experimenters have been forced to construct their own.
