Аннотация:To provide a solution of the problems of seismology, we must have the best quality of the seismic data and must understand the non-seismic noise sources. It is essential to understand how to eliminate or reduce the noise occurring in the seismic devices when the external temperature oscillated. Now, when high-performance computing allows numerically solving almost any specific problem, the theoretical search for analytical solutions seems unproductive. However, an inattention to theory will produce researchers who use these vast resources ineffectively. For a real understanding of the noise cause, it is necessary to know the attenuation and phase shift of external temperature variations during their progress to each element of the device. Theoretical studies are useful at research of applicability of sensors, at developing new sensors, at formulation methods of their installation. Analytic treatments are in the most general form and can be applied to any type of seismic equipment.
