Sound Insulation Testing
What is Sound Insulation Testing ?
The tests are conducted to assess whether the partition between two dwellings provides an acceptable level of resistance to the passage of sound. This is conducted through airborne tests of a wall and impact/airborne testing of a floor.
How many tests do I need ?
Guidance in Approved Document E on pre-completion testing states there should be at least one set of tests carried out 'for every ten dwelling-houses, flats or rooms for residential purposes in a group or sub-group.'
If you have a small development, this may only require one set of tests. We can offer a tailored quote to suit your requirements, so please get in touch for more information.
What does a set of tests consist of ?
In dwelling-houses this comprises of two separate airborne sound insulation tests. One test between habitable rooms on opposite sides of a separating wall. And a second test between another pair of rooms.
In flats without any separating walls, this comprises of both airborne and impact sound insulation tests between the separating floor of a pair of rooms. And another two tests (airborne and impact) between the floor of another pair of rooms.
In flats with both separating walls and floors, the tests are a combination of the above. Two airborne wall tests, two airborne floor tests and two impact floor tests.
What are the performance standards that I need to pass ?
The values vary for each property tested, please see here for more information on this.
An example could be if a ground floor shop with offices above are converted into flats under a material change of use. The relevant performance standards in this case are: Airborne Walls 43dB DnTw + Ctr; Airborne Floor 43dB DnTw + Ctr and Impact Floor 64dB DnTw + Ctr.
