This paper describes the reduction of noise from a pneumatic 18 gauge nail gun. The objectives were to identify the major sources of noise, implement possible noise reduction measures, and evaluate the effectiveness of the modifications. Sound measurements were taken according to a procedure that was developed based on the ANSI S12.15-1992 standard for power tools. Results show that the nail gun was found to have several sources of noise for reduction consideration. Efforts were taken to reduce the two major sources of noise that contributed the highest sound pressure levels. The first major source of noise occurred right after pulling the trigger when the piston ram was forced into front bumper and the second major source was the compressed air exhausting out of the rear of the nail gun. The noise reduction treatments included new bumper materials inside of the nail gun and different types of mufflers on the exhaust. The sound pressure level measurements of the nail gun with mock-up treatments were compared to the baseline measurements to test the effectiveness of the treatments.
