摘要:
A multichannel acoustic emission monitoring system has been developed recently. The system possesses high sensitivity for the sound pressure level of the emission and is concerned with the frequency selection to overcome various background noise disturbances. The signal and data processing unit can process multiple acoustic emission events simultaneously for analyses. The cathode ray tube screen of a computer is used for a real time graphic display of the number of events at individual locations of the emission sources.
