muffler

A muffler that concentrates on suppressing sound waves vibrating 200 to 2,000 times a second--the loudest and most objectionable ones created by rock drills. Because the muffler bypasses the lower frequencies, it does not interfere with the column of air that makes a pneumatic drill function.
