Sound Test Report Information

Sound Test Report Information

All our testing and reportage are undertaken in strict accordance with Annexe B of Approved Document E of the Building Regulations and BS EN ISO 140-4:1998 “Field measurements of airborne sound insulation between rooms” and BS EN ISO 140-7:1998 “Field measurements of impact sound insulation of floors.”

Acoustic_Design_Service

After the sound insulation test a sound test report or certificate should be provided in compliance with Building Regulations Part E. This normally provides the following information:

  1. The company name and/or testers name and address that carried out the test and the accreditation held by the membership organisation.
  2. The client/applicant name.
  3. Site address.
  4. Plots tested
  5. If it was a wall or floor test.
  6. List of equipment used (including details on calibrated equipment) and testing technique.
  7. Confirmation that the test was in accordance with BS EN ISO 140 Part 4 (airborne) and Part 7 (impact).
  8. Measurement procedure.
  9. The results should be calculated in accordance with BS EN ISO 717-1 and 717-2 1997. Detailed test results giving a declaration of a pass or fail.
  10. Date of test. The test results or certificates will be submitted to the verifier during the completion certificate process.

The test duration depends on the amount of sound insulation tests required on the project. Taking into account standard site conditions a set of two airborne wall tests (for a pair of houses) will take one to two hours. A six pack of tests on flats, consisting of two airborne walls, two airborne floor and two impact tests will take between two to three hours. Throughout the sound testing we will require full free uninterrupted access to the units/rooms in all test areas.

We offer an acoustic design service to review the construction detailing. We also offer a sample testing service along with site inspections which provides a ‘one stop acoustic solution’. We visit site during the build process to check for any workmanship issues that may cause problems during the final pre-completion sound testing.

If you would like APT Sound Testing to review your sites acoustic construction, then please speak to us about our acoustic design service, alternatively if you just require sound insulation testing please contact us at: info@aptsoundtesting.co.uk

Acoustic Design Advice

Acoustic Design Advice

To try and help our clients achieve compliance with Approved Document E, we offer the following 4 step acoustic design advice package:

  1. Site Survey Visits – to let us view the existing site construction. This allows us to check for potential problematic construction such as inclusion of lightweight blocks in the existing construction. It also lets us check that the installation teams are installing the acoustic materials as per manufacturer’s guidelines.
  2. Sample Sound Testing – of the existing construction. This offers an accurate overview of the acoustic performance of the existing partitions which enables us to offer a targeted acoustic design using the sound insulation performance of the existing construction.
  3. Acoustic Design Review – a full design review of the proposed developments party walls and floors.
  4. Pre-completion Sound Testing to satisfy Approved Document.

ACOUSTIC_DESIGN

There are many factors to consider when considering good acoustic design, and they are usually split up into 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:

  1. Mass
  2. Isolation
  3. Absorption
  4. Resilience
  5. Stiffness

Also, noise flanking 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. Here are just a few of the potential noise flanking areas:

  1. Structural Steels
  2. Windows built very close to Internal partitions
  3. Inner leaf of the external wall
  4. External wall cavities
  5. External façade or outer leaf
  6. Roof structure

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 also undertake UKAS accredited sound insulation testing providing a ‘one stop’ solution for all your acoustic requirements.
