This report (Contract No. H0133027) presents criteria applicable to noise in coal cleaning plants and discusses generally applicable noise control principles and approaches. The operating characteristics and equipment of coal cleaning plants are described. Considerations entering in the selection and design of noise control means are delineated, and specific means for equipment noise reduction are described. The limited utility of acoustically absorptive materials in plant space is indicated, administrative means for reducing worker noise exposure are pointed out, and ear- protective devices are described briefly. The reduction of plant noise reaching nearby communities is discussed. Programs leading to quieter machines and coal cleaning plants are suggested.
