A ping test is a physical test to determine the natural frequency of an object or assembly.[1] The test consists of instrumenting the object or assembly with measuring devices and then tapping it with another metallic object (usually a hammer.) The undamped system will then vibrate at its natural frequency. The ping test is used on assemblies and objects where vibration can be an issue.
