Sound insulation testing is used to measure the resistance of sound provided by an element of a building (such as a floor or wall) between dwellings. It essentially measures the effectiveness of the sound proofing treatment installed as part of a build or property development. It is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated in 2003.
At the completion of the test, a sound insulation certificate is issued. Without the certificate, Building Control will not release the building completion certificate to the contractors and developers of the project. We understand how important it is for you to get a sound insulation certificate. That’s why we go the extra mile to make sure you get your certificate as quickly as possible. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
Even before you get the certificate, you will receive the results of the test. First, our skilled and competent sound insulation test will engineers give you a verbal result at the site. Then, a written report is sent to you within 24 hours of a working day.

What Sound Insulation Testing Does
Walls and floors that separate dwellings in a building are expected to be sound tested, as mandated by Document E of Building Regulations. Only dwellings that have used Robust Details, which licensed before the installation, are exempted from the test. 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.
What is involved in a Sound 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. ADE goes on to define and group the type of structures that will undergo testing. They are houses, flats and rooms that are being used or are planned to be used as residences; such as student accommodation, care homes and hotel rooms. The volume of testing carried out on each group is written below.
Why is Sound Insulation Testing Relevant?
From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same building. Sound affects our life no matter where we are, at home, work or while relaxing. Places with lowered noise are more comfortable and enabling. Sound testing ensures that noise reduction in a building is effective.
Sound insulation and having privacy while speaking are crucial for a number of reasons. When sound insulation is deficient, it can cause discomfort to occupants. 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. Sound insulation impacts people’s lives in various ways. Then there are developments where each neighbouring room / flat / unit has mixed uses. If the development has passed the sound insulation test, noise is reduced to a minimum.
Do I Need a Sound Insulation 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
Document E of the Building Regulations explains sound insulation testing and makes it a necessity.
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 design details for walls that were tested formerly and meet the sound performance parameters stated by Part E of Building Regulations. Using Robust Details, without taking a test, limits you to the design you’ve picked. With sound testing, however, you’re free to pick from any design, including more cost effective and appropriate ones. This makes it a more efficient process than Robust Details. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.

Sound Insulation Test Time
A sound test is usually conducted just before the construction is completed, and when all the doors and windows have been fixed. However, we can test your building earlier to check for problems. To achieve the best results we would need the following during the test: quietness during the time of the test, 240V power supply and access to all the rooms unless a test plan has been agreed upon prior to the test time.
The Process of a Sound Test
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
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. The noise from the source room and received by the receiver room, and background noise is measured with a sound level meter. Background sound is also calculated. Noise in the receiver room should be 10dB more than the background noise at all frequency measurements, so source noise is set to be greater than background noise. When conducting airborne sound insulation tests, two speakers are placed in each source room. The noise level in the receiving room is measured to get the sound difference between the source and receiving room.
The sound difference is adjusted to make an allowance for reverberation time (time in which the sound decays by 60dB) and background noise in the receiver room. Impact tests are done by placing a standardised tapping machine on the floor. The sound level in the room below it is recorded. This is used in calculating and computing the results. These results are checked against Building Regulations ADE conditions for that kind of dwelling. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.
What Sound Insulation Testing Equipment do we use?
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. An airborne test is used to check how much sound is moving through the air between partitions. Equipment used for the test include a noise generator, speakers and sound level meter. We use a tapping machine, which drops metal hammers onto the floor to create impact noise. We then measure the amount of sound that passes through the partition with a sound level meter in the room under the tapping machine. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. The outcome of the test is written in a report and sent to the customer. This report helps Building Control sign off your building.
A sound test is mandatory for these buildings:
Sound insulation tests examine airborne and impact sound moving through buildings. It is usually undertaken between party walls and floors between buildings or between spaces within a new development.
A structure with 2 or more units/flats
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Redevelopment of a building with a single dwelling into flats
When the development is completed, ADE of Building Regulations should be checked, and sound insulation tested accordingly.
Design that don’t have Robust Details factored in
Architects are able to use pre-tested and approved Robust Details design for partitioning walls and floors. The Robust Details scheme was formed in 2004 by Robust Details Ltd. If the building design does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building Regulations. The minimum requirements during testing will depend on a variety of factors such as if the development is intended to be a permanent dwelling, or classified as “rooms of residential purposes” (e.g. hotels, student accommodation, etc).

Building regulations document E resistance to the passage of sound (England and Wales)
Our certified engineers can come to your building whenever it might suit you to undertake sound insulation testing to Part E of Building Regulations adherence, recognised by Building Control.
Standard division for developments (Scotland)
Section 5.1 of the Scottish Building Standards stipulates that “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 should be performed after construction, using the procedures given in annex 5.C. of the Scottish Standards. Standard 5.1 does not apply to: fully detached houses or roofs or walkways with access solely for maintenance, or solely for the use of the residents of the dwelling below.
Passing a sound insulation test
The best method to guarantee you pass your sound test is to design the building with a view to good sound insulation performance. This shouldn’t be exorbitant, and can save time and cost at the end, without your having to correct sound problem or pay for a re-test. We offer design services that help you construct separating walls and floors with good sound performance that meet ADE demands. Our consultation process is led by your project requirements and may include assessment of design reports, test of the development and multiple site visits. The following criteria should be followed to provide you with the best chance of passing your sound test: Install and make sure that all external and internal doors and windows are operational Fit and seal skirting boards Light fittings and switches and plug sockets are fitted 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.
Investigation and report certificates
We try to issue a certificate to give you the details of the test evaluation and report, by the next day. After the test, our site engineers will provide verbal results and advise you on how to solve potential problem or future areas of concern. 6. Even before you get the certificate, you get the verbal results of the test. First, our completely skilled and competent sound insulation test engineers give you a verbal result at the site. They also offer advice on potential problems. Then the test report certificate is sent to you within 24 working hours, when feasible.
The way the results look
Your test certificate will show if your development passed or failed the test and show if it adheres to the requirements of Part E of Building Regulations. We can provide professional advice on designs that will surpass Document E standards if the building fails the test.
