  • Measurement of Ambient Magnetic Field Noise for ThroughtheEarth TTE Communications and Historical Comparisons
    Measurement of Ambient Magnetic Field Noise for Through-the-Earth (TTE) Communications and Historical Comparisons
    Epstein B ;
    Jin GY
    2024/06/01 | Mining Publications
    Recent results of low-frequency (<6 kHz) magnetic field noise measurements at underground coal mines are presented. A comparison of these results to measurements made 35-40 years ago suggests that the magnetic field noise has increased substantially since this period of time. The ambient noise level is an important factor in the operation of through-the-earth (TTE) communications systems, and the data presented herein are a consideration in the design of future TTE systems.
