Abstract:  
A shot peening intensity measurement device has a holder and a test disk formed from a resonant and hardened material. The test disk is held to the holder with a cover that threads onto the holder and clamps the test disk. The holder and test disk form a chamber where a portion of the test disk is unsupported. A measurement device, such as a microphone or other non-contacting device detects vibrations from the test disk when shot or media contacts the test disk.
