Abstract
Here, we compare the two acoustic methods named cross-correlation and auto-correlation to locate pinhole locations in a gas-pipeline. The cross-correlation method that determines the location from the cross-correlation of two acoustic signals detected at two terminals of the pipeline is effective for pipelines with greater acoustic damping. Whereas the auto-correlation method that determines the location from the auto-correlation of the acoustic signal detected at one terminal of the pipeline is effective for those with less acoustic damping.<>
