Part E Airborne and Impact Sound Testing
Sound Insulation Testing Birmingham
Professional pre-completion sound testing for new-build homes, apartments, HMOs, conversions and mixed-use developments throughout Birmingham and the West Midlands.
Sound Insulation Testing in Birmingham
One Stop Consult provides professional sound insulation testing for builders, developers, architects, housing associations and homeowners throughout Birmingham and the surrounding West Midlands area.
Sound testing measures how effectively separating walls and floors reduce the transfer of airborne and impact noise between adjoining dwellings.
Testing is commonly required under Approved Document E before new-build attached homes, apartments and residential conversions can receive final Building Control approval.
Sound Testing Across Birmingham and the West Midlands
We regularly support projects throughout Birmingham City Centre, Edgbaston, Harborne, Selly Oak, Moseley, Kings Heath, Hall Green, Erdington, Sutton Coldfield, Yardley, Handsworth and Perry Barr.
Nearby coverage also includes Solihull, Smethwick, West Bromwich, Walsall, Wolverhampton, Dudley, Bromsgrove, Redditch and surrounding West Midlands areas.
What Is Sound Insulation Testing?
Sound insulation testing checks the acoustic performance of separating walls and floors between adjoining dwellings.
Specialist equipment is used to generate and measure controlled sound levels within the source and receiving rooms.
The measured performance is compared with the applicable Building Regulations criteria to determine whether the construction achieves the required standard.
Acoustic Testing Services
Our Sound Insulation Testing Services
Testing packages are tailored to the building type, separating construction and sample requirements.
01
Airborne Wall Testing
Testing the reduction of airborne sound through party walls between adjoining dwellings.
02
Airborne Floor Testing
Measuring airborne sound insulation through separating floors between flats or maisonettes.
03
Impact Floor Testing
Measuring the transmission of impact noise through separating floors using a standard tapping machine.
04
Part E Compliance Reports
Detailed reports suitable for submission to Building Control following completion of the tests.
05
Failure Investigations
Practical investigation and advice where a wall or floor does not initially meet the required performance.
06
Retesting
Follow-up testing after appropriate remedial acoustic work has been completed.
Airborne Sound Insulation Testing
Airborne testing measures how effectively a separating wall or floor reduces noise such as speech, television, music and general household sound.
A loudspeaker generates a controlled sound signal in one room while measurements are taken on both sides of the separating element.

Impact Sound Insulation Testing
Impact testing measures noise transmitted through a separating floor by activities such as footsteps, dropped objects and moving furniture.
A calibrated tapping machine is placed on the floor above and sound levels are measured within the receiving room below.
The test is generally required where dwellings are positioned vertically above one another.
Typical Project Types
When Is Sound Insulation Testing Required?
Testing is commonly required where separate dwellings share walls or floors and a suitable alternative compliance route is not used.
Sound Testing and Robust Details
Some new-build attached dwellings may use the Robust Details scheme as an alternative route to pre-completion testing.
This only applies where the separating construction is properly registered and built in accordance with the relevant Robust Detail requirements.
Residential conversions generally require testing because the Robust Details route does not normally apply to converted buildings.
Preparing for Testing
When Is the Building Ready?
The project should be substantially complete so the test reflects the final acoustic performance of the construction.
Windows and Doors Installed
External openings should be complete and capable of being closed during the test.
Internal Finishes Complete
Plasterboard, plastering, skirtings and relevant finishes should reflect the completed building.
Services Complete
Service penetrations should be sealed and associated systems sufficiently commissioned where necessary.
Rooms Cleared
Excess materials and obstructions should be removed from the rooms being tested.
Low Background Noise
Construction activity and external noise should be controlled where reasonably possible.
Access to Both Sides
Safe access is required to the source and receiving rooms for each test location.
Common Acoustic Weaknesses
Why Walls and Floors Sometimes Fail
Failures are often caused by gaps, flanking paths or changes from the intended separating construction.
Unsealed Service Penetrations
Gaps around sockets, pipes, cables and ducts can significantly reduce sound insulation.
Poor Perimeter Sealing
Open junctions around walls, floors and ceilings can create direct leakage paths.
Incorrect Wall Build-Up
Missing boards, insulation or cavity details can reduce the intended acoustic performance.
Rigid Connections
Unintended structural bridges can transfer vibration around the separating element.
Poor Floor Junctions
Incomplete resilient layers, perimeter strips or ceiling systems can affect airborne and impact performance.
Flanking Transmission
Sound can bypass the tested wall or floor through adjoining walls, ceilings, voids and structural elements.

Important Sound Insulation Testing Information
Testing requirements depend on the building type, compliance route, separating construction and sample agreed with Building Control. A successful result cannot be guaranteed before testing because performance depends on workmanship, junction details, flanking transmission and completion of the building.
The tested rooms must be sufficiently complete, secure and accessible. Where a result does not meet the applicable criteria, further investigation, remedial work and retesting may be required. One Stop Consult provides consultancy and coordination support through experienced acoustic testing specialists.
