Abstract

A modification of an acoustic seal or its environment, due to a natural degradation or a man-made falsification, causes differences between detector signals captured at distant time intervals. The correlation:signal difference - seal modification can be quantified by a computer simulation of the experiment. Both the inevitable measurement uncertainty and the noise in signal transmission, however, reduce the significance of the signal difference. We, therefore, use a simulation based upon the Monte Carlo technique confining those parameter domains within which significant modifications of the seal - environment system can be detected reliably.
