Sound Testing

To demonstrate compliance with Approved Document E of the Current Building Regulations.

At Sound Solution Consultants, we have all the expertise necessary to accurately measure the Acoustic performance of both airborne and impact noise within your property.

Our specialist testing can quantify the amount of noise reduction between different attached dwellings, such as in hotels or blocks of flats.  This data, combined with our expert consultancy, will enable you to ensure your building is in keeping with the criteria set out by Approved Document Part E of the Building Regulations.


‘Part E’ Explained

Current government policy dictates that "new housing and residential environments should be well designed and should make a significant contribution to promoting urban renaissance and improving the quality of life".

If you’re responsible for a build – be it a conversion or new – then it is your responsibility to manage the process so that the project meets the necessary criteria upon completion. 

The current limits are:

For hostels, hotels and bedsits, they are:

Do I need Sound Insulation Tests?

There are a number of different scenarios in which Sound Insulation Tests are necessary:

  • To ascertain the in-situ sound insulation of a residential property against the performance requirements of The Building Regulations Approved Document E or Code for Sustainable Homes.
  • To ascertain the in-situ sound insulation of a wall or floor before works are carried out, such as a wood floor test with management agents and wood floor treatments.
  • To ascertain the in-situ sound insulation of a school against the performance requirements of Building Bulletin 93 acting as an extension of The Building Regulations Approved Document E.
  • To ascertain the in-situ sound insulation of an office against the performance requirements recommended by BS8233 or BREEAM New Construction technical guide.
  • To ascertain the level of in-situ performance of walls and floors surrounding industrial or commercial buildings (such as pubs and nightclubs).


We’re certified

Sound testing has to be carried out by a fully certified sound consultant.  If it isn’t, then building control might refuse to accept the results.  Sound Solution Consultants are registered as a fully certified UKAS Accredited Laboratory.  We are are able to provide Accredited Sound Insulation test reports suitable for being submitted to your Building Control Officer.

Our Accreditation number is 4686, and you can obtain further verification of this at:


The two main methods

There are currently two techniques in place to ensure that Approved Document Part E – which is the standard for building regulations in both England & Wales – is complied with.

Pre-completion sound testing.  Prior to completion of the building, in-depth tests must be carried out by a certified test body in order to evaluate the current state of the space.  Before a property can be fully signed off, a copy of the initial test results must be approved by the local building control office.

Robust details.  Suitable for new builds only, a Robust Detail is a separating wall or floor construction that is assessed and approved by RDL.  It must consistently exceed the performance standards dictated as given in part E, and the sound insulation work must be carried out using a predefined methodology and using a specific type of product as detailed in the Robust Details manual.  Robust Detail designs are pre-tested to standards beyond the minimum required by Approved Document E of the building regulations.  As a result, those using the scheme will not have to carry out additional pre-completion sound testing. To qualify in the scheme you have to register the build and details being used, prior to starting construction.
