A successful Architectural Acoustics solution significantly reduces unwanted noise in the built environment by containing sound and vibrations within a room or series of rooms. Vibra-Sonic Control is a solutions expert in Architectural Acoustics supplying leading engineers and acoustical consultants with products and materials for their Architectural Acoustics projects.
Floating floors are secondary floors built above the structural floor with an air gap between them. Typically floating floors are used for vibration, sound and impact isolation where they can dramatically increase Sound Transmission Class (STC) and Impact Isolation Class (IIC) rating between rooms. Common applications would be for a very noisy equipment room located over prime office space, a gymnasium, a theatre room or a music room.
Vibra-Sonic Control offers two effective options for floating floors both by Vibration Isolation leader Mason Industries, the Jack-Up Floor Slab System and the Form-Work System.
Mason Jack-Up System
The Jack-Up system was originated in 1965 by Mason and has thousands of successful installations to its credit. With this system, mounts are placed along with rebar on the structural floor, concrete is poured and once cured the floor is jacked-up to the desired height.
Mason Form-Work System
The Form-Work System utilizes molded rubber mounts in set heights which are placed on the structural floor, covered with plywood and then covered with concrete.
While Floating Floors are the most effective way of reducing sound transmission and vibration to the room below, additional options are required to protect the comfort of occupants in the floor above. In these situations, a Suspended Ceiling System can provide the high STC solution required. Suspended Ceilings are created using isolation hangers to suspend a gypsum barrier ceiling from the structural ceiling.
Where noise issues are occurring due to solid connections through structural walls, isolating walls are used to break those sound paths. Isolating walls are created by adding a secondary gypsum wall with an air gap between it and the structural wall. These can be used in conjunction with the floating floors and isolated ceiling to create a “room within a room”.
Entire buildings can be exposed to vibration generated from either above ground or underground vehicles or equipment. To curb the vibration from entering the building’s structure, isolators are placed at the base of the structure.
