Geophone (SM-24), frequency band 10 Hz to 240 Hz, standard resistance 375 Ω
A geophone is a device that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured voltage from the base line is called the seismic response and is analyzed for structure of the Earth.
