Characterization of Acoustic Source Signal Response in Oxidized Autocombusted Coal Temperature Inversion Experiments

Characterization of Acoustic Source Signal Response in Oxidized Autocombusted Coal Temperature Inversion Experiments

The measurement error of sound travel time, one of the most critical parameters in acoustic temperature measurement, is significantly affected by the type of sound source signal. In order to select more appropriate sound source signals, a sound source signal preference study of loose coal acoustic t...
