Our Sound Testing Process
1. Answer any queries
We confirm a date. Our engineer will call you ahead of the test date to talk you through the preparation and process plus agree the timings.
4. On the day of testing
Airborne tests involve creating noise of a known level (approximately 100dB) on one side of the party/separating wall/floor and measuring the volume on the other side to calculate the amount of noise that the wall or floor is insulating. Measurements are taken in multiple planes and positions, reverberation (echo) and background noise are taken into account. The result is expressed in decibels (dB) as DnTw with corrections including traffic noise (Ctr).
Impact testing is done using a tapping machine that simulates footfall on the uncovered floor surface. The level of noise is measured in the unit below and the result is expressed in dB as LnT.
New flats and houses must achieve greater than or equal to 45dB sound insulation for airborne tests and less than or equal to 62dB for impact tests. Converted properties have slightly easier targets.
Testing typically takes place very close to completion but before carpets or other flooring is laid.
Please see FAQs.
We issue a short-form UKAS test report including certificates for each test.
If the worst should happen and there is a failure, we put you in touch with an experienced acoustician who can provide design/remedial advice ahead of retesting.
NEED SOME HELP?
Through our sister company (Robust Testing Solutions Ltd) and selected partners, we are able to offer advice and support on sound insulation as well as other construction-related acoustic consultancy services for planning, site noise, etc.
IF THINGS DON’T GO TO PLAN
In addition, if buildings fail to achieve the required levels, the consultants we work with can diagnose the cause and suggest remedial solutions.
AND THERE’S MORE ...
We also carry out air tightness testing:
- Houses and flats for Part L or low energy schemes
- Commercial buildings for Part L
- Smoke shafts for smoke ventilation
- Plenums/raised access floors
- Hospital isolation areas – Isolation suites, operating theatres, etc
- To identify the source of smells/smoke
