Architectural Acoustics | Vibra Sonic Control

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

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.

Suspended Ceilings

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.

Isolated Walls

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”.

Building Isolation

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.

Glossary

LDS stands for Low Dynamic Stiffness AASHTO Bridge Bearing Natural Rubber to minimize noise and vibration transmission. Maximum Dynamic Stiffness is 1.4.

STC stands for Sound Transmission Class, which is a single-number rating of a material’s ability to resist sound transfer. The higher the STC rating the more noise is blocked.

Air Gaps – When dealing with monolithic building components such as a solid concrete, creating an air gap raises the STC significantly more than adding mass.

INR stands for Impact Noise Rating, which is single-number rating of the material’s ability to resist the transfer of impact noise. The higher the INR rating the better the impact noise blocking.

Impact Isolation Class, IIC, measures how well a building floor lessens impact sounds, such as footsteps. A larger number means more attenuation. The scale, like the decibel scale for sound, is logarithmic.
