Detachment?
When gently moving a metal rod along the surface of a stone, mortar or plaster, the sound produced indicates if there is a detachment (low-pitched sound) or not (high-pitched sound) [Click the image below to see the film and listen...]. However, be careful not to scratch the tested surface!
Unfortunately, this technique has its limitations: it does not detect very thick detachments or contour scalings.
