Engineering: Acoustical Noise Control, Vibration Isolation and Building Isolation offered by Mason Industries Inc.

Architectural Ceiling Hangers

Floating Floors remain the most effective way of reducing sound transmission and vibration from the floor above. However, there are many situations where a floating floor is impractical or not economically feasible, so an isolated ceiling becomes the practical choice.
There are two types of ceilings.There are the simple acoustical tile ceilings that surround the lighting fixtures, duct outlets, etc., and conceal unsightly ductwork, piping and electrical work. The acoustical tile reduces the reflected noise within the room, but does virtually nothing to reduce sound transmission from above. It does not prevent noise within the room traveling upward or over partition walls that are not floor to structural ceiling.

BUILDING ISOLATION DISCUSSION

Noise and vibration isolators are used to prevent the downward transmission of vibration from a machine to a structure, the upward transfer from the structure to a sensitive machine or to isolate a complete building from ground vibration. Ground vibration may be generated by above ground or under ground passenger or freight trains, or heavy motorized vehicles, such as trucks or military equipment. The source may be industrial hammers, power plants or industrial machines, close enough to cause a problem.

ARCHITECTURAL ISOLATION DISCUSSION

To the Architect:
We have been floating floors, resiliently suspending ceilings and isolating walls for close to 45 years. The need for this acoustical reinforcement has been well established in textbooks, sales literature and acoustical engineering recommendations. Therefore, we thought it would be helpful to offer a handbook of specific methods and suggested specifications rather than just print another interesting but rather general brochure.

NEOPRENE SOUND ISOLATION SYSTEM

A New Total Concept Approach to Low Cost Noise Isolation Systems The noise isolation efficiency of mechanical or gypsum board walls and ceilings is seriously threatened when solid connections are made to noisy structural walls, ceilings or floors. Simple inexpensive neoprene isolators can break these sound paths when used as wall braces, ceiling hangers or floor supports. The modest cost of this protection is more than paid for by quieter occupied space.

EAFM Mounts for Floating Floors

In 1976, the acoustical community asked us to develop a floating floor mounting that would last as long as the building and provide response frequencies lower than two inch (50mm) thick fiberglass.

EAFM Mounts for Sound and Vibration Control

The definition of a rubber mounting is any configuration, round, square or rectangular with a known capacity and deflection. Acoustical solutions are in the 6 - 8 Hz frequency range. However, these very same low stress isolators can be stacked with steel shim plates between to achieve lower frequencies for vibration isolation.
