What Sound Insulation Levels do i need to achieve pass my sound testing?
Sound insulation testing or precompletion sound testing must be carried out on new build dwellings as well as on converted dwellings. The dwellings will either require an Airborne sound test or an Airborne and Impact sound test. Airborne tests are carried out on separating walls between habitable rooms of dwellings such as houses or flats. Airborne and Impact sound tests are carried out on the separating partition floors between habitable rooms of flats. All sound insulation testing must comply with Approved Document E of Building Regulations.
All of our sound insulation tests are carried out in accordance with ISO 140-4 and ISO 140-7 and we are a UKAS accredited test laboratory, so you can be safe in the knowledge that all our sound testing is carried out to the highest standards in compliance with ISO 17025/2017.
New build properties need to meet the requirements of DnTw+Ctr ≥45dB (more than) and LnTw ≤62dB (less than). Conversion properties need to meet the requirements of DnTw+Ctr ≥43dB (more than) and LnTw ≤64dB (less than).
