Unless plans were fully approved prior to 1 July 2003, sound insulation testing will be required on your London development between rooms or spaces that share a common area of separating wall and/or floor as stipulated in Building Regulations Part E for the passage of sound. Sound insulation Testing is not generally required for internal walls and floors within a dwelling-house, flat or room for residential purposes; however all internal partitions should be designed to achieve 40dB.
The buildings that require sound testing are:
- Dwelling-houses, flats or rooms for residential purposes created by conversion of existing buildings or new build rooms for residential purposes will need to be tested if work starts after 1 July 2004.
- New build dwelling-houses and flats will need to be tested if work starts after 1 July 2004.
The main aim of Sound testing in London is to ensure that minimum standards of sound resistance have not been compromised by poor workmanship and/or poor design. You are normally required to undertake sound testing to each type of construction, i.e. if you have a mixture of brick, blockwork, timber and metal studwork walls all four types would need to be tested, followed by a 10% sample of that type using the equipment shown in Plate A below.
Plate A – Our Sound Test Equipment.
For instance, if you have a project with 25 flats you would be required to do 3 x 6 pack of tests; each 6 pack contains 2 airborne wall, 2 airborne floor and 2 impact sound tests; however if any test failures occur, then the number of sound tests may need to increase on the development. When sound test failures occur, then the design and construction of the failed partitions will need to be revisited to try and evaluate the reasons for the failure; thereafter, agreement can be reached on how to rectify problem.
APT Sound Testing can advise on all types of acoustic design, whether it’s accomplished during initial construction or during a refurbishment/renovation project. We also undertake UKAS accredited sound testing providing a ‘one stop’ solution for all your acoustic requirements.
