When sound testing is required
New dwellings that are attached to each other — flats, semi-detached houses, terraces — require sound testing to show compliance with Part E of the Building Regulations (Resistance to the Passage of Sound). Conversions creating attached dwellings need it too.
Testing is carried out with calibrated sound meters through party walls and party floors, and consists of airborne tests (a loudspeaker one side, measured the other) and, for floors, impact tests (a tapping machine on the floor above). Results are reported against the Part E performance standards for Building Control.
Getting it right before we test
Sound test failures usually trace back to detailing: gaps around joists penetrating party walls, missing mineral wool in cavities, rigid bridging across resilient layers. If you’re unsure about a detail, send it over before the build gets there — far cheaper than remedial work after a failed test.
Environmental noise surveys
For commercial projects and planning applications we also undertake environmental noise assessments — from a single air conditioning plant to residential developments near roads, rail or aircraft noise. Surveys are conducted to current standards and reported to satisfy Environmental Health, Planning or Building Control, including sound insulation recommendations where needed.
