A systems approach is developed for control of punch press noise. The result is a flow diagram which can be used as a guideline for evaluating the feasibility of noise control through engineering. Extensive experimental results are also reported to provide examples of the techniques described in the systems approach. Reductions of air sources are described through the use of commercially available mufflers for air exhausts and silencers for pneumatic parts ejectors. Control of impact noise is described through reduction of radiating area, reduction of machine speed and force reduction through changes in tooling, variations in work-piece material and changes in the operation. In addition, possible modifications to press designs are considered. These include consideration of stiffness, mass and damping. Finally consideration is given to noise control in the path through use of absorption barriers and enclosures.
