The application of the methods of electromagnetic sounding for geophysical research is considered. The results of synchronous measurements of the Earth’s electric and magnetic fields made by different types of sensors in the frequency range of 0.002–7000 Hz are presented. Various approaches to obtaining the estimate of sensor noise are considered. A technique for quantitative estimation of the self noise level of the sensors under study and the characteristics of the natural field on the basis of two- and three-channel schemes of synchronous measurements is proposed. Comparison of experimental noise estimates with computational data is given. It is shown that the magnetometer based on a magnetomodulation transducer has an unacceptably high level of self noise for using it in applications related to the measurement of natural variable magnetic field.
