Abstract
It is well established that the best opportunity to address industrial noise control problems is during the design phase of new plants. Solution at this stage are both economically and technically more effective than later retrofits. Thus, unique opportunities are often presented to management in the planning phase for new plants to make decisions that are also acoustically advantageous. A simple example of this was recently found in which a mining company, engaged in the processing of silica sand, had built two screening towers similar in function but with different constructions. To provide the mining industry with quantitative information to guide them in assessing the potential acoustical benefits of facility design, these mineral processing plants with similar operations, but contrasting designs, were studied. To characterize the acoustical environments in these facilities, the spatial distribution of sound levels in the two plants was measured and compared using an external sound source. The results of this study clearly show the advantages of an open plant design in achieving reduced worker noise exposure levels.
