A ''geophone'' is a mechanical device that transforms seismic energy into electrical voltage ([[:file:seismic-data-acquisition-on-land_fig6.png|Figure 6]]). Individual geophones are often wired together and configured in arrays along a cable. These arrays are designed much the same as source arrays and for the same basic reasons, that is, to maximize detection of reflected energy and to reduce the amount of noise. However, it is important that for any geophone array to work, the individual phones must be properly planted and not just thrown out on the ground, stuck into trees, hung in bushes, or set on rocks.
