The concept must be able to account for minor changes in operating frequency on a specific drill. In addition to that, the drill operating frequency varies from one drill to another. The thesis also aims to lay the mathematical foundation to design an attenuating handle for a specific drill with a specific operating frequency. All the objectives must be obtained without noticeable sacrifices in drill control or performance.enSIMRACGAP 634VibrationRock drillVibration white fingerHand-arm vibrationConference PresentationDe wet Strydom, J.
