Sound Flanking Pathways

Since the advent of Building Regulations Part E, we have literally undertaken thousands of sound tests throughout London and the rest of the UK. During this time we have managed to build up a considerable knowledge base for typical sound flanking pathways in new and conversion projects.

To help consultants and contractors we have comprised a list of the main noise flanking paths:

Dividing Floor Partitions – Through Floor and Floor Joist Space (if insulation has not been installed or direct fixing to joists without a drop ceiling below the partition under test)
Dividing Ceiling Partitions – Above and Through the Ceiling Space (where an adequate acoustic break has not been carried on through the ceiling void)
Shared Structural Building Components – Floor Boards, Floor Joists, Continuous Drywall Partitions, Continuous Concrete Floors, and Cement Block Walls.
Through Structural Steel (structural steel beams are often a major cause of noise transmission as plasterboard is often fixed directly to the steel without sound breaks)
Plumbing Chases – Junctures between the Walls & Floor Slab Above or at the Exterior Wall Juncture (this should be filed with mortar etc. to add mass to this weakened areas.
Through Windows (if they are no double glazed or have secondary glazing as a minimum)
Fixtures & Outlets – Light Switches, Telephone Outlets, and Recessed Lighting Fixtures (if penetrations have been cut back to back with the opposite dwelling under test)
Structural Joints – Perimeter Joints at Wall & Floor, Through Wall & Ceiling Junctures (these should be filled with acoustic mastic.
Around the End of the Partition Through the Adjacent Wall (acoustic mastic should be used to seal this junction)

APT Sound Testing offer a ‘one stop’ design package for all types of acoustic design and sound testing throughout London and the UK, whether it’s on a new build or conversion development.

We are also a UKAS accredited laboratory for both air tightness and sound insulation testing, which means you can be safe in the knowledge that we offer a high quality service and the results will be accepted by the tasked building control.
