__FORCETOC__

==Fundamentals==

Acoustic resonance analysis is used to detect inhomogeneities and defects (microstructural defects, inclusions, cracks) in test objects that oscillate at their resonance frequencies after external excitation ([[Impact Loading Plastics|impact]], shock) (see also: [[Errors|errors]]). This includes all metallic, non-metallic inorganic (glass), ceramic and brittle [[Polymer|polymeric]] [[Material & Werkstoff|materials]]. The prerequisite is that the internal damping of the test object is not so great that a sufficiently long sound signal is available. Resonance analysis is a volume-oriented testing method which, as a ‘[[Sound Test|sound test]]’, is one of the oldest subjective [[Non-destructive Testing (NDT)|non-destructive testing methods]] (NDT). In contrast, its industrial application for objective, computer-assisted acoustic analysis in series production has only been successfully introduced since the mid-1990s. The method is used, among other things, to inspect castings, sintered parts, ceramic products (pottery, roof tiles), forgings and cold or hot-formed parts, especially in industrial sectors with high production volumes, such as the automotive industry.
