A pilot study to identify and control noise emanating from punch presses demonstrates that a 10 decibel reduction in peak noise level can be achieved by installing commercially available mufflers. Clearance is an important parameter in determining the level of punching noise. Substitution of a shear punch can lower the peak pressure level by 5 to 8 decibel. A significant portion of the noise radiated during punch press operation is due to the transient vibration of the workpiece, a fact suggesting that clamping might be effective in further reducing punch press noise.
