GER-4239 Power Plant Near-Field Noise Considerations

The two major factors in limiting exposure are the noise level an individual is exposed to, and the amount of time an individual is exposed to a particular level of noise. Each of these may be controlled in various ways. Control of the exposure noise level may be achieved by: 1a) Reduction at the source 1b) Use of enclosures, barrier walls, etc.
