Acoustic Noise Barriers also called Sound Barriers are used to block noise from entering or escaping from one area to another area.Noise Barriers can be made of many different materials depending on the application. Sound barriers block noise by using materials that provide mass. Typically the more mass the better the material will stop sound waves from penetrating through a structure. Acoustic barriers are designed for specific applications.

Acoustical Panel Sound BarrierFor example a light weight composite fiberglass sound wall is designed to be used on structures where other materials such as concrete are too heavy to structure mount. Some noise barriers are made into another type of composite material such as an acoustical curtain. Acoustical curtains typically have a mass loaded vinyl barrier septum between layers of a scrim quilted fiberglass. This not only blocks sound, it will also absorb the sound.

Other examples are soundproof foams that are typically constructed using a 1lb per square foot barrier septum between two layers of foam. Acoustic enclosures are another example of a sound barrier application. Many industrial plants have enclosures placed around machinery to lower the ambient noise level to increase worker comfort. One of the many benefits to the plant other than the worker comfort is the plant does not have to be on the hearing conservation program. This lowers the plants insurance rates and increases worker productivity.
