What Does Airborne Sound Testing Involve?

Separating walls and floors are tested for airborne sound. This should be undertaken by an accredited member of an organisation – APT are UKAS accredited for Sound Testing. When testing airborne sound performance two adjoining rooms are used. A sound source (loudspeaker) is set up in one room on one side of the separating wall or floor being sound tested. The sound levels in each are room are then measured using a sound level meter.

The background levels in the receiver room are measured and the reverberation time in the receiver room is also measured. From the results, the airborne sound insulation (DnT,w + Ctr) is calculated and compared to the requirements of Approved Document E.
