The operator's exposure to vibration is negligible. Very low vibration is passed into the structure which helps to reduce damage and structure-borne noise. This method is less messy than using breakers as the debris is in larger pieces and less dust is produced. Noise levels are very low, both for the operators and the environment.

Quantifying the Vibration Level. The vibration amplitude, which is the characteristic that describes the severity of the vibration, can be quantified in several ways. On the diagram, the relationship between the peak-to-peak level, the peak level, the average level, and the RMS level of a sinewave is shown.
