Wherever you are in the UK, we can assist with sound insulation testing for building regulation compliance at competitive prices with a quick turnaround time.

Our sound testing services cover new build houses and apartments, conversions or change of use, as well as schools and healthcare facilities.

Building Regulations Approved Document E - why you need sound insulation testing

Guidance on achieving building regulation approval is provided by Building Regulation Approved Documents. The requirement for noise is set out in the Building Regulations Approved Document E for testing the sound insulation of buildings. Part E contains guidance on the resistance of the passage of sound within and between domestic premises, and also within schools.

For residential developments, there is a requirement for walls and floors between adjoining dwellings to be sound tested to ensure they do not exceed acceptable noise transmission levels.

This noise falls into two categories: airborne (e.g. conversation) and impact (e.g. footsteps). The extent of testing required depends on the size and design of the development.

We always recommend that you get in touch at the earliest possible point in your project. This way we can plan ahead, helping you to avoid hassle and costly delays.

Sound insulation services

When you work with us, you will receive a comprehensive sound insulation testing service, including:

  • Airborne & impact sound insulation testing in accordance with The Building Regulations Approved Document E which is a requirement for all new build & converted dwellings where there is an unregistered separating floor or wall partition.
  • Sound insulation testing of existing buildings to confirm sound insulation levels and to allow for any remedial measures needed to improve performance, as necessary.
  • Sound testing to partitions in schools, colleges, universities, offices, and other buildings.
  • Reverberation time assessments as recommended by The Building Regulations Approved Document E for communal areas, i.e. school halls, classrooms, gymnasiums.

Thorough planning & design to avoid costly mistakes

In addition to sound insulation testing at pre-completion stage, we can also offer consultancy services as part of the planning and design process.

Prior to installation, using industry leading software, we can calculate the noise transmission through existing walls and floors taking into account the materials and design you are planning to use.

These calculations will highlight any potential 'non-compliant' walls and floors prior to installation, helping to avoid any costly remedial work later down the line.

Our consultants can work alongside your architect or builder from an early stage to ensure your project is Approved Document E compliant

Professional memberships and affiliation

You can feel reassured that our consultants are members of the The Institute of Acoustics, and have SITMA (Sound Insulation Testing & Measurement Association) accreditation.

We use the highest quality testing equipment and materials, alongside the latest software.

    Case Studies


    Sound Insulation Testing in Shifnal, Shropshire

    NoiseAir were out on site recently carrying out sound insulation testing at a recently converted property in Telford, Shropshire. The project involved the conversion of an old chapel into six new apartments.

    Sound insulation testing (or ‘Part E testing’) covers both airborne and impact noise tests, which for example might reflect noise from footsteps in an apartment above, or music and conversation heard from the apartment next door. Inevitably, unwanted noise transmission can present a major problem for residents, so adequate sound insulation is vital on a development such as this.

    Our consultants carried out several tests on site which all passed and the developer was issued with a sound insulation test certificate. The certificate can then be presented to the buildings inspector as part of the building work sign off.
