Acoustic design considerations to help you pass your London Sound Test
We often get asked by our London clients, how they can improve the sound insulation in their walls and floors to pass precompletion sound testing in London. To try and simplify this, we have written the following article explaining the main acoustic design considerations for undertaking and improving the acoustic characteristics of party walls and floors to achieve compliance with Approved Document E of Building Regulations.
As a starting point, you need to consider the following five basic acoustic design considerations, they are:
- Adding Mass – such as adding dense finishing boards such as ply, OSB, drywall or plasterboard.
- Providing Isolation – such as constructing independent linings, or introducing acoustic brackets, acoustic hangers or resilient channels, which will help to decouple drywall from the rest of the building’s structure.
- Adding Absorption – such as open cell woven types of material such as RW45 Acoustic Wool Cavity Insulation, which provides a soaking up or absorption of the acoustic energy entering it.
- Providing Resilience – There are quite a few ‘acoustic membranes’ on the marketplace, most membranes are 3-6mm in thicknesses and is commonly installed within walls, ceilings and floors to mitigate airborne and impact sound.
- Adding Stiffness – adding extra noggins between wall frames and/or floor joists can add stiffness to the overall construction of the party walls/floors.
