Acoustic emission generated by composite pressure vessels, in theory, should be relatively straight forward to analyze and to draw conclusions from if damage is present and/or damage is progressing by measuring the amount of acoustic emission generated and/or the rate at which acoustic emission is detected. A high amplitude acoustic emission hit from the same source to sensor distance should, in theory, be from a more severe source than a lower amplitude hit. Similarly, a
