Abstract
An acoustical enclosure system, particularly designed for overtable circular saws employed in cutting such materials as metal shapes, is disclosed. The system includes an acoustical enclosure covering the saw and a pair of vibration damping arms covering the workpiece being sawed. This combination of elements results in substantially reduced noise levels within the sawing environment.
