The acoustic resonance test is a technique for a non-destructive test of elastic components. The incentive of this method is the possibility to carry out a quick and automated testing by evaluating the merely physical component parameters at low investment and operation costs. The acoustic resonance test evaluates the natural vibration. Two equal components must obligatorily present the same natural vibration behavior. If the behavior differs, the components shows physical causes that can be relevant to quality. The natural harmonics of a component is measured by stimulating the resonance with the help of an impact hammer.
