Noise control of rubber-tired front-end loaders used in surface mining. Open file report 13 Apr 79-31 May 83
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 able to be easily installed by mine personnel. Two loaders, a Caterpillar 988 and an International H-400B, were chosen for the program and the noise sources and acoustic paths that contribute to the operator's noise exposure were identified. Retrofit noise control treatments were designed and installed on the loaders, and noise reductions 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 yrs. The results of the program were communicated to the mining industry through a series of noise control workshops and a field manual. The workshops were given in nine States across the United States and more than 440 manuals were distributed to attendees. An audiovisual slide presentation was also developed that summarizes the program.
