Airborne and Impact Sound Testing Explained

Airborne wall testing measures how effectively a separating wall reduces sound such as speech, television and music between horizontally adjoining flats.

Airborne floor testing measures airborne noise travelling through a separating floor between vertically adjoining flats.

Impact floor testing measures structure-borne noise such as footsteps and dropped objects. A calibrated tapping machine is operated on the floor above while sound levels are measured in the dwelling below.

How to Prepare for Part E Testing

Testing should be completed once construction is substantially complete and after second fix.

Doors and windows Internal and external doors and windows must be fitted, closable and complete.

Trickle vents Trickle vents must be fitted or capable of being temporarily blocked during testing.

Clear rooms All selected test rooms must be clear of furniture, debris and construction materials.

Floor-Covering Requirements

Impact sound testing should be carried out before final floor coverings are installed. The tapping machine must operate on the appropriate bare floor construction to provide a representative compliance measurement.

If a soft floor covering has already been fitted, at least 50% must be capable of being pulled back to expose the floor below. Any floor covering present during testing may be recorded in the report and could affect acceptance by Building Control.

Parking, Safety and Site Conditions

Parking should be provided within approximately 20 metres of the test property
Advise us before the visit if suitable parking cannot be provided
Power tools and noisy construction work must be paused near all test rooms
Vehicle movements close to the receiving rooms should be avoided
Children, pets and unauthorised personnel must remain outside the test rooms
The site contact must be available to provide access and sign off the visit

Safety notice: the airborne sound source can produce levels exceeding 110 dB(A) and may start remotely. Only the testing engineer may remain in the relevant room while the equipment is operating.
