Good Acoustic Design & Construction (Part 1)

Clients often ask APT Sound Testing what acoustic design measures they need to improve the sound insulation results on their projects to pass Part E Sound Testing.

In our experience the main considerations for a separating wall and floor between dwellings generally has at least one of five key factors. If used together or in various combinations they will improve sound insulation properties over a wide range of frequencies. The main factors are:

  • Mass
  • Isolation
  • Absorption
  • Resilience
  • Stiffness

Unfortunately, simply constructing a good separating wall or floor may not in itself provide sufficient sound insulation and you could end up with a sound test failure as shown in he video below:

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.
