Abstract
The objective of this project was to develop noise control designs for secondary crushers in taconite plants. The project included reducing the noise levels of the secondary crusher at the Jackson County Iron Company, such that the levels at 1 meter from the basic unit and 1 1/2 meters above the floor are 85 decibels, a-weighted network (dba). The difference in cost of design of a 90-dba residual level in contrast with an 85-dba level was to be determined. The resultant dba was to be obtained at the 924- and 933-levels associated with the crusher and console levels.
