Noise Control Technology for Selected Woodworking Machinery

摘要

Methods to minimize noise produced by vibrations and aerodynamic phenomena in the woodworking industry (SIC-2511) are examined. Sources of woodworking machinery noise and associated control procedures are described. The control of workpiece vibration noise, tool vibration noise, and machine vibration noise is considered. It is noted that while total acoustical enclosures are useful in many instances, they can be cumbersome and yield reduced efficiencies in certain cases. Two cases for which considerable difficulty arises in the use of total enclosures are the surfacing of long materials where it is not practical to totally enclose the entire source, and the circular sawing operation for which total enclosures are often impractical. These two cases are discussed in considerable detail.
