Good Acoustic Design & Construction (Part 2)

There are many misconceptions when it comes to acoustics. Unfortunately by simply constructing a good separating wall or floor partition this may not in itself provide sufficient sound insulation to pass the sound testing for Part E as the junctions of each separating wall and/or floor with other parts of the building are equally as important. There may be other potential issues such as flanking sound transmission that can occur via construction components such as:

1. The internal partitions
2. The inner leaf of the external wall
3. The external wall cavities
4. The external facade or outer leaf
5. The roof structure
6. The foundations

The overall design and construction system should therefore be considered and not just the separating wall or floor partitions. Flanking sound transmission may in some cases be the dominant pathway between adjoining dwellings, especially in existing buildings where you are planning to convert offices/large houses into flats where there are large existing penetrations through the floors.

The video below shows an existing floor failing the sound test.

APT Sound Testing can advise on all types of acoustic design, whether it’s accomplished during initial construction or during a refurbishment/renovation project. We have the technical experience to help identify and rectify your soundproofing or noise control problem.
