BM TRADA provides a nationwide UKAS accredited, site-based sound insulation and acoustic testing service for flats, houses, rooms for residential purposes, schools and other industrial buildings.

We undertake acoustic testing (sound testing) to the British Standards.

  • BS EN ISO 140-4 is the measurement of sound insulation of separating walls and floors between rooms.
  • BS EN ISO 140-7 tests the impact sound insulation of separating floors to simulate footfall

To purchase copies of either of the BSI standards follow the links below:

We can also offer further acoustic testing services to specialised standards including:

  • Building Bulletin 93 Acoustic (BB93).
  • Requirements for existing and new schools are assessed using Building Bulletin 93 for educational buildings
  • Health Technical Memorandum 08-01 (Healthcare premises). This standard sets out the recommended acoustic criteria for the de-sign and management of new healthcare facilities

What is sound insulation testing?

Sound testing, also referred to as acoustic testing, is the measurement of how much sound is stopped by separating walls or floors between dwellings and rooms such as classrooms, hotel rooms, student residences and offices.

By making a controlled noise on one side of the separating wall or floor and measuring how much sound is being received on the other side, we can tell how much sound is stopped by the structure.

In England and Wales, Approved Document E of the Building Regulations requires new buildings and conversions to demonstrate reasonable levels of airborne and impact sound insulation performance between separating walls and floors.

There are two ways of complying with the sound insulation requirements that are contained with Approved Document E which are:

  • Build to Robust Details, which is a set of specific design details that have previously been tested to show compliance or
  • Conduct on-site pre-completion sound testing.

This is where sound testing is performed on site prior to the building being completed and signed off by Building Control. The testing does not need to encompass all of the buildings but must be representative of the units contained within the building project.

Pre-completion sound testing is often the preferred method as it allows greater flexibility in design details which may be less limiting, more cost-effective and achieve improved sound insulation performance.
