Noise Reduction during the Production of Thick Walled Steel Constructions by Means of Impact Processing Techniques

摘要

A number of measures are described that can be taken to reduce the noise generated by techniques using impactors in the production of thickwalled steel constructions. In most workshops, the noise usually exceeds by far the legal noise limit. Suggestions, based on laboratory tests, are made for noise reduction by modification of the manufacturing procedure, by adaptation of the tools, and by diminishing the excitation and emission characteristics of the body under construction. By means of specific examples of container and steelframe construction, it is demonstrated that noise generated by impact processes can indeed be reduced to a large extent.
