What is Sound Insulation Testing?A sound insulation test, also known as an acoustics test measures the output of sound from neighbouring occupancies.
Sound insulation tests, or pre-completion tests must be carried out on new build properties as well as converted properties.
A property will either require an Airborne test or an Airborne and Impact test. Airborne tests are carried out on all separating walls between habitable rooms of flats and houses. Airborne and Impact tests are carried out on the separating floors between habitable rooms of flats. Sound insulation tests must comply with Building Regulations Approved Document E. New build property needs to meet the requirements of DnTw+Ctr ≥45dB and LnTw ≤62dB. Conversion properties need to meet the requirements of DnTw+Ctr ≥43dB and LnTw ≤64dB. All of our sound insulation tests are carried out in accordance with ISO 140-4 and ISO 140-7. All of our test engineers are members of the Institute of Acoustics and RJ Acoustics is UKAS registered. |
