Abstract
The objectives of this program were to assess and demonstrate retrofit noise control technology for front-end loaders. The treatments had to be practical, cost effective, and easily installed by mine personnel. The noise sources and acoustic paths that contribute to operator noise exposure were identified for two selected loaders. Retrofit noise control treatments were designed and installed on the loaders, and noise reduction of more than 10 dba at the operator position were achieved on both machines. The retrofit packages are low cost and have been field tested in two mines for more than 2 yr. The results of the program were communicated to the mining industry through a series of workshops and a field manual. The workshops were given in 9 states across the United States, and more than 440 manuals were distributed.
