Abstract
This invention relates to the testing of apparatus used for on-line acoustic detection of bearing defects, particularly in railroad applications. A loudspeaker on each side of the section of track, in response to a microprocessor, generates simulated acoustic signatures characteristics of various bearing defects. The microprocessor additionally sends corresponding simulated train speed signals to the apparatus. The invention monitors the apparatus for the appropriate alarm signal.
