Acoustic emission (AE) is defined as high-frequency elastic waves emitted from defects such as small cracks within a material when stressed in the laboratory. Investing in a multichannel data acquisition system provides the means to monitor dynamics of the fracturing process. The purpose of this suggested method is to describe the experimental setup and devices used to monitor AE in laboratory testing of rock. The instrumentation includes the AE sensor, preamplifier, frequency filter, main amplifier, AE rate counter, and analog-to-digital (A/D) recorder, to provide fundamental knowledge on material and specimen behavior in laboratory experiments.
