Abstract
The objective of this study was to evaluate the acoustical and cost effectiveness and the operational practicality of prefabricated acoustical enclosures applied to a taconite crusher. The enclosures were designed for durability, ease of assembly, and ease of access for crusher maintenance. Field measurements of noise were made on the periphery of enclosures on a secondary crusher at the Jackson County Iron Company in Black River Falls, Wisconsin. Noise reduction achieved by the enclosures was sufficient to permit reduction of crusher room noise to 90 dba, provided that other sources are appropriately treated and acoustical adsorption is provided in the crusher room. Secondary crusher noise was reduced 10 to 15 dba by the enclosures.
