A Seismic Communications Investigation Employing a Piezoelectric Transducer

The purpose of this effort was to investigate the feasibility of employing a piezoelectric transducer for seismic communications in mine environments. The transducer incorporated a high Q, spring-mass resonator to load the air side of the piezoelectric crystal. The resonant frequency was seismic loa...
