Sound Insulation Testing

Need sound insulation testing for your development?

Air Tightness Solutions provides professional sound insulation testing for developers, contractors, self-build clients and property conversions across the UK.

Whether you’re completing a new residential development, converting an existing building or preparing for Building Control sign-off, we’ll help you arrange your testing, minimise delays and provide clear reporting once testing is complete.

We understand that sound testing is often one of the final steps before project completion, so we work with you to ensure testing is carried out at the right time.

What is sound insulation testing?

Sound insulation testing, sometimes called acoustic testing or pre-completion sound testing, measures how effectively walls and floors reduce the transmission of sound between adjoining properties.

The testing is typically required to demonstrate compliance with Approved Document E (Resistance to the Passage of Sound) of the Building Regulations for new residential developments and many building conversions.

Testing usually includes two types of assessment:

Airborne sound testing

Measures sound travelling through the air, such as:

  • Conversations
  • Television noise
  • Music
  • General household noise

Impact sound testing

Measures sound transmitted through floors, including:

  • Footsteps
  • Dropped objects
  • Furniture movement

Together, these tests demonstrate whether separating walls and floors achieve the required acoustic performance.

Who needs sound insulation testing?

We regularly carry out testing for:

  • New build housing developments
  • Apartment blocks
  • Flat conversions
  • Office-to-residential conversions
  • Mixed-use developments
  • Housing associations
  • Self-build projects

Whether you’re completing a single dwelling or a large multi-plot development, we can provide the testing required before completion.

Why is sound insulation testing important?

Good acoustic performance creates quieter, more comfortable homes while helping developers satisfy Building Regulations.

Testing helps demonstrate that separating walls and floors have been constructed correctly and are performing as intended.

By arranging testing at the correct stage, developers can:

  • Demonstrate compliance with Part E
  • Reduce the risk of delays at handover
  • Identify issues before project completion
  • Improve occupant comfort
  • Complete the certification process efficiently

Why choose Air Tightness Solutions?

Sound insulation testing is often carried out alongside other building compliance requirements, so choosing an experienced testing company helps simplify the process.
With over 50 years of combined experience and delivering industry training for over 10 years, Air Tightness Solutions brings leading expertise to every project.
Providing short lead times and a reactive approach to our clients requirements prevents unnecessary delays.

We provide compliant solutions with ATTMA accredited engineers for Air Testing.

When should sound insulation testing be carried out?

Testing should only take place once the dwellings are substantially complete.

Typically this means:

  • Windows and external doors installed
  • Internal doors fitted
  • Floor finishes completed where required
  • Kitchens and bathrooms installed
  • Mechanical services operational
  • Building secure and weatherproof

Testing too early may result in aborted visits or failed tests, so it’s important that the property is fully prepared beforehand.

04. On-site testing

Our engineer carries out the required airborne and impact sound tests.

05. Reporting

Following successful completion of the testing, we issue your report.

Need to coordinate multiple compliance tests? Ask us about combining services to reduce site visits.

Common reasons developments fail sound testing

Most failures are caused by relatively common construction issues, including:

  • Gaps around service penetrations
  • Poor workmanship around separating walls
  • Missing acoustic insulation
  • Bridging between separating elements
  • Incorrect floor build-ups
  • Poor sealing around sockets and pipework

Careful preparation before testing can significantly improve the likelihood of achieving a successful result.

Supporting developers and contractors

We understand that sound insulation testing is usually one part of a much larger construction programme.

Our team works closely with developers, contractors and site managers to ensure testing is arranged efficiently and with minimal disruption.

We can also advise on:

  • Preparing properties for testing
  • Typical testing requirements
  • Common causes of failure
  • Reporting timescales
  • Next steps following testing

Frequently asked questions

What is sound insulation testing?

Sound insulation testing measures how effectively walls and floors reduce the transmission of airborne and impact noise between adjoining dwellings.

Is sound testing required for Building Regulations?

For many new residential developments and material change of use conversions, yes. Testing is commonly required to demonstrate compliance with Approved Document E.

How long does an air test take?

This depends on the size and complexity of the development, but most projects can be completed within a scheduled site visit.

What happens if a plot fails?

If the required standard isn’t achieved, remedial works can usually be completed before the area is retested.

When will I receive my report?

Reports are provided promptly following completion of the testing.
