Abstract

Electrodynamic seismographs, which were first used by B. B. Golitsyn* [1] to study vibration in the Earth’s crust are now widely used in seismology [2] and seismic prospecting [3] in the USSR and eleswhere. Seismological instruments usually operate in the frequency ranges 0.1–0.5 to 10–30 cps those used for prospecting, in the ranges 3–5 to 100–500 cps. There are also many types of electrodynamic vibrations detectors used for measuring vibrations in metal structures and buildings, which operate in the range from 10–20 cps to several kilocycles [4], In particular, in 1937–1938 the author and G. A. Surin developed an electrodynamic vibration detector for use at audio frequencies [5], intended for investigating vibrations in buildings and in the Earth.
