WebThe geophone measures ground motion in three dimensions: Vertical: Up and down. Longitudinal: Forwards and backwards from the blast. Transverse: Side to side. The microphone measures air overpressure, which is the additional pressure generated by a blast above normal atmospheric pressure. WebWith that out of the way, this is how a piezoelectric microphone actually works: In a crystal microphone, a thin piece of Piezoelectric material is attached to a diaphragm, and as the diaphragm deflects the crystal, it receives opposite charges on either side.
