Equipment for a Pulse Method of Sound Velocity Measurement in Rock and Sediment.

Abstract

The most frequently used laboratory technique for measuring the velocity of compressional elastic waves in rock specimens, sediments, and other materials is the so-called pulse method in which the travel time of acoustic pulses over a known path length in a specimen is determined. The equipment basically consists of two transducers, one of which supplies acoustic pulses to the sample being measured and the other receiving the pulses after they have traveled a certain distance through the sample. The received signal is displayed on an oscilloscope screen and the travel time determined there by the operator who picks the first arrived signal by eye.
