Power plants can generate continuous noise from transformers, cooling equipment, fans, exhaust systems and other machinery operating throughout the facility. When that sound reaches nearby homes, businesses or property boundaries, controlling it can become a difficult engineering and community-relations issue.
Power plant noise barriers help interrupt the path between noisy equipment and nearby receptors without requiring every sound source to be placed inside a full enclosure. This can be especially useful at existing plants where equipment access, ventilation and limited space make noise control more complicated.
Barrier design matters, though. A reflective wall may redirect sound toward another part of the property, while an absorptive noise barrier is designed to reduce reflected sound energy as well as block the direct path of the noise. For power generation sites with multiple noise sources, that difference can have a major effect on how the finished system performs.
Instead, local municipalities and governments have been charged with devising and maintaining their noise ordinances. These may range anywhere from non-existent regulation to severely strict noise control.
Older businesses most likely did not leave extra space for retrofitting noise barriers to reduce noise once new businesses and residential homes are added to the area. This is because many companies did not realize that reflecting noise could cause higher frequencies of noise and increased noise levels.
Power Plants Need To Diffuse Different Kinds Of Noise Pollution
Although, noise pollution can come from a variety of sources, power plants are one of the biggest culprits. These large industrial complexes house a plethora of machinery and structures that increase or maximize noise. Most of this machinery is housed in areas that require heat dissipation through:
- Exhaust Portals
- Fans
- and Other Openings
The main problem with power plants is that reducing the noise used to require blocking heat exhausts with enclosures that prevented the heat levels from dropping to safe levels.
Sometimes, the reflective noise barriers incorporated into older structures actually increased the nuisance noise or pushed it up and outward into the community. This problem was realized across the United States in the past few decades with few effective solutions until recently.
Minimizing Noise Pollution
Sound Fighter® Systems has created a noise absorbing material that is easy to install, cost-effective to retrofit to existing facilities, reduces noise substantially, and can be customized to fit in with the surrounding environment through color use, adaptive cutouts, and re-configurable systems.
Noise Absorption Panels Are Superior To Reflective Materials
The use of high-performance noise barriers is a growing requirement, but many companies do not incorporate these controls into building plans because of the lack of regulation in previous years. Noise absorbing panels best-meet these complex noise-control needs because it is absorbed rather than reflected into another area.
Water treatment plants are another application that has benefited from this technology in recent years. With growing populations, and cities increasing in industrial and commercial development, the reduction of noise from industrial applications is increasingly vital to all communities.
Creating an atmosphere where people can live alongside the sources of energy that they require is crucial for developing communities. There are many industrial sources of noise pollution, but power generation and transmission facilities have often been the source of contentious noise problems.
Today, many companies are required by law to minimize noise pollution they create for neighbors even when these neighbors come after they utility station or power plant is built. This means a costly retrofit that are logistically challenging and can require significant structural modifications.
With noise absorption systems from Sound Fighter® Systems, power plants and water treatment facilities can significantly reduce offensive noise levels with a customized noise absorption barrier that can be removed, changed, added to, and modified if necessary. This solution reduces long-term cost and enables them to maintain a higher level of community and industrial compliance.

FAQ’s
What types of power plant equipment can noise barriers help control?
Power plant noise barriers can be used around equipment such as transformers, cooling systems, fans, ventilation openings, compressors and other sources of airborne industrial noise.
The right barrier layout depends on the noise source, its frequency range, nearby receptors and the amount of airflow or equipment access that must be maintained. In locations where reflected sound is a concern, an absorptive barrier can help limit the amount of sound energy that bounces back toward the plant or surrounding properties.
For retrofit projects, modular absorptive panels can also be useful when space, access or existing structures make a full acoustic enclosure impractical.
