Acoustic Treatments for Floors
This section includes many common techniques for improving the sound insulation of floors within commercial buildings. Information is supplied for a range of common intermediate floor constructions.
In general, improvement techniques for intermediate floors can be divided into: applied treatments to the upper floor surface or the application of independent or semi-isolated lower ceiling linings. Additionally, for joisted floors, improvement in airborne sound reduction can be effected by the introduction of sound absorbent materials within the floor void itself.
Most treatments will improve both airborne sound insulation and impact sound insulation. Some floor constructions may inherently provide adequate airborne sound transmission values (e.g. high mass cast concrete floors). In this situation, only improvement in impact sound insulation may be of practical consideration.
Applied treatments to the upper floor surface are described for concrete floors and timber / metal joisted floors. For alternative floor constructions please discuss the specific condition with our technical department
The techniques outlined for the application of independent or semi-isolated ceiling linings are general to most floor constructions.
