When drums are played, the sound development mainly leads to low frequencies, which also causes body vibrations. The vibrations are transmitted to floors and adjacent walls, and the sound also spreads to adjacent rooms and parts of the building. To prevent this unpleasant sound development, the drum kit should be decoupled from the other building structures. A good solution is to build a platform with suitable sound absorbers. Composite foam/recycled foam is the right solution for the low frequencies generated when playing drums.

Platform construction
When planning the platform construction, it is particularly important to ensure that the platform is not in direct contact with the walls. The first step in planning is therefore to choose the right location. It is best to use a composite foam with a thickness of approx. 60 mm and a density of 140 kg/m3 for the lining. It is important to ensure that the entire surface of the platform is lined with composite foam. To prevent sound bridges, the foam must be laid over the entire surface and there must be no gaps.

Floating floor
A load-bearing layer in the form of a chipboard can now be applied to the composite foam and glued to the composite foam. This creates a floating floor that acts as a structure-borne sound insulation. The platform should not be screwed into the floor, as this could again create sound bridges and impair the elasticity of the “floating floor”.
