Assume that you have a machine shop consisting of a high-speed, strip-fed punch press producing the final product. The equipment only takes 25% of the production hall of your machine shop and has a generated noise level of 102 dBA when operating at an average of 280 strokes per minute. This equipment should work 16 hours per day. Following the provided information does the equipment noise level permissible for the device operator(s) working 6-8 hours daily in the production hall? If not, what possible solutions do you suggest to reduce the noise level of the device and make it possible to run the equipment for 16hours/day continuously? Note that the only modification to the equipment itself is applying a specific type of anti-vibration damping sheets which can lower the noise level maximum 7 dB.
