    Noise and Vibration Reduction of a Vibrating

    vibrating screens. Vibrating screens generate sound levels ranging from 90 to 95 dB(A) during clean bituminous coal processing and 95 to 100 dB(A) during refuse and anthracite processing (Ungar et al., 1974). Because they are used to size, separate and dewater both coal and refuse (rock) of various sizes, screens may be located
