MECHANOELECTRICAL TRANSFORMATIONS IN QUARTZ AND QUARTZ-BEARING ROCKS UNDER ACOUSTIC ACTION

摘要

The data are reported for investigation into a frequency spectrum of an electromagnetic signal recorded in artificial crystal quartz and natural quartzite subject to a piezoacoustic action. Variations in the amplitude and duration of an exciting acoustic signal, as well as in the distance between a device, which receives the electromagnetic signal, and an emitting surface change the amplitude-frequency characteristics of the electromagnetic signals.
