A method of peening a product to be peened by shooting a shooting material with compressed air from a shooting nozzle to the product. The shot peening method and a device thereof can confirm the state of the shooting material during peening of the product, prevent a sensor from being worn, and reduce maintenance and calibration of the sensor. A converter is installed at the shooting nozzle for detecting elastic waves generated by the shooting material passing through the shooting nozzle and converting the elastic waves to high frequency electric signals to output. Therefore, the method measures and monitors the state value of the shooting material passing through the shooting nozzle according to the high frequency electric signals. |
