Abstract
A method of modifying a percussion tool to provide noise reduction, and a percussion tool having effective noise damping characteristics. In the method of the present invention, a troublesome noise frequency radiated by the tool is identified, and a resonant bending mode shape for the tool is determined, which bending mode shape corresponds to the identified noise frequency. The tool is then assembled and a structural discontinuity is introduced at a point along the length of the tool which is a predetermined axial distance from a selected antinode of the bending mode shape to provide an impedance mismatch at that point. The tool, which is of predetermined length, is formed of one or more sections, each of which is of a selected length. The lengths of the sections are carefully determined such that when the tool is in assembled condition, impedance mismatches are provided at selected points along the length of the tool, to provide noise reduction of several troublesome noise frequencies.
