Sound insulation testing involves the use of specialist equipment to examine how much sound is reduced off by floors and walls, of a building. It checks if a dwelling’s sound proofing treatment meets the requirements set out in Approved Document E. It has been a mandatory part of the Building Regulations for new build and refurbishment projects since Approved Document E (ADE) was revised in 2003.
Not doing so is a costly venture for developers and contractors as Building Control will not give a completion certificate for developments that have not undergone the test. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. We pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.
Our fully trained sound insulation test engineers can be on site when you need them. Your AF Acoustics engineer will give you immediate verbal results from the sound test, and you can will have a written report by the following working day.

What Sound Testing Does
Developments must test all walls, floors and ceilings that separate buildings or neighbours in a dwelling, to conform to Approved Document E (ADE) of the Building Regulations. You may not have to test your building if you used Robust Details which were approved before their installation. The airborne and impact sound going through new and old structures are evaluated by sound testing. This can impact adjoining walls and floors between the structures.
The Procedures Involved in a Sound Insulation Test
Workers on a site will vacate the premises while the sound test is being conducted. This will facilitate an enabling and quiet environment for the tests to be carried out. The way a sound test is administered depends on the size and type of building and the development’s condition. Most of the time the test will be conducted in 90 minutes, for a simple, regular sized construction.
The sound testing engineers then proceed to give verbal results on the site and offer helpful advice on any problem areas noticed during the duration of the test.
A full and thorough report with the certificate of the test will be given to you within 24 working hours. The sound insulation testing methodology has been outlined by Document E of the Building Regulations. The document states that every 10 units in a sub-group or group should undergo one set of test, and defines a sub-group in Section 1. Buildings are divided into three kinds for the test – houses, flats and rooms built for or converted to residential dwellings, like student accommodation, care homes and hotel rooms. How much testing that should be done on each group is listed below:
Importance of Sound Insulation Testing
Sound insulation testing is required because ADE of Building Regulations has made it compulsory for all new buildings to take a sound test prior to finishing construction. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. This Approved Document, as part of UK Building Regulations helps to ensure that new buildings are constructed to minimum standards that provide reasonable resistance to sound from other parts of the same building and from adjacent buildings. Sound testing is essential due to the fact that sound impacts us wherever we are, whether it’s at home, leisure or the office. Reduced noise in the partitions and flooring of a structure leads to greater ease and a more efficient environment.
Sound insulation and speech privacy are critical for a variety of reasons. Inadequate sound insulation can be extremely distressing to those affected by it. For instance, in an apartment building, the neighbour upstairs might invite friends over during the weekend and put on loud music. The inhabitant downstairs might spend night hours as work time. If the sound insulation is inefficient, this could lead to lots of problems. This is one way sound insulation can affect how a person lives. There are also developments where the neighbouring units are used for different purposes. In such cases, a sound test ensures that the noise coming from each unit is minimal.
Do You Need a Sound Test?
If you’re doing one of the following, then you need a sound test:
- Constructing a building that has two or more units
- Constructing a nursing home or rooms that will be lived in, e.g. hotel room or hostel
- Converting a single development to flats
- Using designs where Robust Details are not included
Sound insulation is covered and made mandatory under Approved Document E of The Building Regulations.
Either you follow the pre-completion sound testing process stipulated therein or you use Robust Details. This way, you have conformed to the requirements. Robust details are separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. When you use it, you don’t have to take a sound insulation test. However, you must abide strictly by the design from the Robust Details approved list. Sound testing provides more flexibility by allowing different designs and is often therefore more cost effective in many ways compared to the Robust Details Scheme. When on-site pre–completion building sound tests are taken, architects have more scope with their design and can increase the sound insulation performance of the construction.
How much does sound insulation testing cost?
Simply contact us and we will be able to provide a free, no obligation quotation as to the requirements and costs for your development. We have tested all types and sizes of construction in the UK and issue a report and sound test certificate within 24 working hours. We offer one of the best prices. If you get a better price from another company, let us know and we will try to beat it.
When can I carry out the sound insulation tests?
Ideally, we would conduct a test when a development nears completion, and once all internal and external doors and windows have been fitted. We can test earlier to check if there are any problems. To be able to conduct sound insulation testing we require the provision of a 240V power supply, and a quiet site (a noisy site can make conducting the tests extremely difficult). Access will be required to all rooms of the development unless a test schedule is determined in advance.
How a Sound Test is Done
Sound testing procedure is quite simple and our engineers are happy to explain this on site. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.
The test uses a dodecahedron speaker and pink or white noise generator for source sound. The sound source is placed in the largest room of the two. A sound level meter calculates the noise in the source room and receiver room. Background noise is measured to make certain that the source noise is greater. This way the standard of the receiver room having a 10dB higher noise level at all calculated frequencies can be realised. Airborne sound testing is done in a similar way. First, two speaker positions are used for each source room. Then, the level of sound in the receiver room is measured so that the difference in noise level between the two rooms can be calculated.
This difference is modified to include background noise in the receiver room and reverberation time – time whereby a sound fades away in a closed space by 60dB. Impact sound tests are performed with a tapping machine positioned on the floor of the source room. The sound pressure level at the receiving room, which is below the source room, is measured. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. This is a simple way of explaining how a sound test is conducted.
Sound Testing Equipment to Expect
Our accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the building regulations. Airborne sound test is the measurement of sound moving through the air through a wall or floor. The equipment we use are a sound level meter, loudspeaker and white or pink noise generator. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. Test results, which are approved by Building Control and used to sign off the building, are recorded in a report and sent to the client.
A sound test is mandatory for these buildings:
For sound testing we usually undertake impact and airborne sound test on buildings. This affects the separating floors and walls between habitable rooms of buildings and developments.
A new building with not less than two rooms
With the sound test, you can be certain that the property has a good acoustic performance.
Conversions of former single dwelling properties into flats
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Design that don’t have Robust Details factored in
The Robust Details scheme was set up in 2004 by Robust Details Ltd as a way to help architects and builders design and construct separating elements with the confidence that the separating wall and/or floor will be capable of achieving the sound performance parameters in Approved Document E, and comply with the Building Regulations. If the design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. Minimum criterion differs based on the type and purpose of the development. A development with rooms intended as residences, like a hostel or hotel, won’t have the same criteria as a structure for permanent dwelling.

Scotland Standard division for properties
In the words of Section 5.1 of the Scottish Building Standards, “Every building must be designed and constructed in such a way that each wall and floor separating one dwelling from another, or one dwelling from another part of the building, or one dwelling from a building other than a dwelling, will limit the transmission of noise to the dwelling to a level that will not threaten the health of the occupants or inconvenience them in the course of normal domestic activities.” Tests, which are conducted after building utilizing the methodology given in annex 5.C. of the Scottish Standard 5.1 does not apply to: completely disconnected houses, rooftops and walkways with access exclusively for the use of the occupants of the home underneath.
How to pass a sound test
All you have to do to pass your sound test is include adequate sound insulation in the design. That way, you save time and cost for repair work and re-test. If you are unsure of how to build the separating floor and wall constructions and associated junctions across your development to satisfy the requirements of Document E 2003, we can offer design advice. Whether you want some initial tests on your project, or comprehensive reports at the end, we can help you at the level that you need. The following conditions will provide you with an ample chance of passing the sound test: Inner and outer doors and windows have been installed and can be used Skirting boards are fixed Plug sockets, light switches and fittings are in place and working. Our experienced acoustic consultants work with developers, contractors, architects and planners of all sizes from the early design stage to help minimise any potential issues right through to project completion, ensuring that all properties are compliant with Building Regulations Document E 2003.
