AC Outdoor Noise Barrier Noishield product line consists of pre-engineered, modular acoustical components that can be easily configured and assembled into enclosures, screens, partial enclosures and barriers to provide sound attenuation for many kinds of outdoor industrial, community and environmental noise problems. Outdoor noise problems, also known as community noise problems, environmental noise problems or simply noise pollution tend to refer to issues of noise related disturbances in a community or neighborhood caused by outdoor noise sources such as traffic, cooling towers, rooftop mechanical equipment, air conditioners, generators, manufacturing facilities, deep well pumps, utility sites and construction. Untreated, these noise sources may violate state and local noise level regulations based on zoning or cause annoyance in the community, disturb sleep or interfere with quality of life. IAC can solve these problems with a properly designed Noise Barrier Wall, Screen or Noise Enclosure using our Moduline Noishield line of modular acoustical metal panel products.
