Abstract

A pneumatic tool sound dampening system includes a housing that has a first end, a second end and a perimeter wall extending between the first and second ends. The first and second ends are open. The housing includes a first section including the first end and a second section including the second end. The first end is fluidly coupled to an exhaust port of the pneumatic drive apparatus. An interior of the first section forms an expanding cone extending toward the second section. A funnel is positioned within the second section. The funnel forms a decreasing cone extending away from the first section and toward the second end. The funnel is fluidly coupled to the second end.
