摘要

The absorber has fiberwool that comprises a density in a range between 0.2 gram per centimeter cube to 0.3 gram per centimeter cube. The fiberwool has a thickness in a range between 0.5 millimeter to 15 millimeters, where the sound absorber is provided in a discharge passage of a pneumatic tool (10). The tool comprises an air inlet section (11) at its rear end, and compressed air from the air inlet section drives a rotor of the tool.
