Abstract
A method is provided that enables the identification of a region of a layered composite component that a test signal has passed through. The method comprises applying a label to the test signal as it passes through the region, such that the label applied to the test signal is indicative of the said region. The labelled signal can be identified by a sensor, even if the signal is of low strength and amongst a lot of noise, such as that caused by the multiple reflections and refractions that take place when an acoustic signal passes through a layered composite component.
