ACOUSTICAL REDESIGN OF THE FOREST GROVE BURNER LABORATORY,
Abstract
The report describes the design used in reconstructing the Forest Grove Burner Laboratory for quieter operation. It reviews the technology available and describes the design evolved for achieving the desired results. Briefly, the reconstructed unit of the establishment consists of a double-walled concrete burner cubicle with sound-insulating doors and windows, an air intake stack rising from one end, and an exhaust stack from the other. In both stacks, sound attenuation is accomplished chiefly by panels of rock wool in perforated steel that divide the stacks into ducts a few inches wide. The intake stacks are entirely new, and the exhaust stacks are modifications of those already present. On the basis of a detailed analysis, it is predicted that sound escaping by any route will not exceed the allowed level of 90 decibels outside the building. A qualitative report on actual performance, indicating that satisfactory results have been achieved, is included.
