Aug 02, 2014· At 500 meters (0.3 miles) away, that sound pressure level drops to 38 decibels. In most places, according to Keith Longtin of GE Renewable Energy, background noise ranges from 40 to 45 decibels, meaning that a turbine's noise would be lost amongst it. For the stillest, most rural areas, Longtin says the background noise is 30 decibels.
The Raymond® Bowl Mill is considered the finest vertical roller mill available for pulverizing coal. The typical Raymond bowl mill system is designed to simultaneously dry, pulverize, and classify solid fuels to 95% passing 200 mesh (<5%R75μ) with a wide range of capacities from 24 to 150 stph.
Managing noise in the coal industry to protect hearing Noise can be described as 'unwanted sound' or as 'sound of such intensity or character sufficient to disturb and/or discomfort the listener'.

reduce idling noise levels. Use smoother profile blocks with low blade projection. Slotted or perforated table lips can reduce idling noise levels. Reductions in noise can be made by reducing the cutter's rotational speed, and increasing the number of knives on the cutter. There should be a noise enclosure, either as an integral

To begin, noise levels must be determined at the locations from which the complaints arise. Once levels have been determined, the next step is to apply acceptable noise level criteria to each location and thus to determine the required noise reductions, generally as a function of octave or one-third octave frequency bands (see chapter 1).
