An overview of noise control in the power industry.

The owners and operators of power facilities are being increasingly confronted with problems of noise control. These problems are often lumped together with others under the umbrella of ‘‘Environmental/Health Issues’’ without recognition of their unique character. Properly addressed, these factors can lead to solutions that are well integrated into a plant’s design and operation. This overview presents the aspects of noise control that are both common with other industries and unique to the power business. Aspects unique to the power industry derive from regulatory and licensing requirements. Particularly for the community, it is demanded that the facility be ‘‘operable’’ in compliance with applicable noise limits. If regulations are not clear, successful operation may be determined by public acceptance. This is most often driven by the tonal content of the noise. Noise sources found in the power industry, such as fossil fired steam and combustion turbines, are discussed.
