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.
