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. New structures and reconstructed developments have been mandated by the Building Regulations to test for sound upon completion, since Approved Document E (ADE) was reappraised 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. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. We take great pride in providing our certificates to you as soon as possible after the tests.
Our highly capable sound test engineers will be available on site when you need them. They will give you a verbal result of the test, once taken and a written report will be issued to you by the following working day.

What is a Sound Test?
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. Sound insulation tests examine airborne and impact sound moving between separating walls and floors. The tests include party walls and floors between structures or between spaces within a new development.
What is involved in a Sound Test
The sound test itself produces very high levels of noise but also requires relatively quiet conditions on site. For these reasons, any workforce in the testing area will have to leave temporarily to ensure test accuracy. A sound insulation test on a project is taken according to the scale and complexity of the construction and the conditions of the site. Most of the time the test will be conducted in 90 minutes, for a simple, regular sized construction.
Once this is done, the sound test engineers give temporary results while they’re still on the site. They will also provide suggested solutions to possible problem areas noted during testing.
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 also states the categories of developments that should be tested. There are three: rooms, flats and houses (including bungalows) that are lived in. Examples are student accommodation, hotel rooms and care homes. Find below the testing stipulation for each kind of development.
Why Sound Testing is Required
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. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. The aim of Approved Documet E of the Building Regulations is to establish a minimum standard for the reduction in noise levels between all dwellings in a new or refurbished building. Testing for sound insulation is vital because sound influences how we live in the office, while relaxing or in the house. Restricting the sound that moves between floors and walls could result in a more relaxed and better surrounding.
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 example, in a block of flats, your upstairs neighbour may (and not unreasonably) like to have friends over at the weekend, resulting in the playing of loud music. However, the downstairs occupant may be working nights and sleeping throughout the day, thus any inadequate sound insulation between these two flats would cause great disturbance and distress to the downstairs occupant. Sound insulation helps improve the quality of a person’s life in diverse ways. It can be useful in dwellings with neighbouring units/flats/rooms which have diverse purposes, by guaranteeing that an occupant in a room will hear as little noise as possible from the neighbouring room.
Does Your Development Need a Sound Insulation Test?
You need a sound insulation test if you’re:
- Constructing a nursing home or residential rooms like hostel or hotel rooms,
- Converting a building with a single dwelling into flats,
- Constructing a property with two or more units,
- Using designs without Robust Details to build
Building Regulations Part E discusses sound testing in detail and has made it a requirement.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. If you choose the latter, you must use Robust Details which are a approved design details for partitioning walls and floors. Using Robust Details, without taking a test, limits you to the design you’ve picked. Sound insulation testing is a more flexible approach. You can pick from a plethora of designs, as opposed to Robust Details. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.

When can I carry out the sound insulation tests?
The ideal period for a sound insulation test is after the fitting of windows and doors, and before the building is finished. If you want, AF Acoustics can conduct tests before then to find out if there are any problems on your property. These are the things we need to conduct the test:
- 240V power supply
- A quiet environment
- Access to all the units of the structure unless places to test have been decided before then.
How a Sound Test is Done
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.
A pink or white noise generator and a large speaker is used for the test in the biggest room between the two undergoing testing. The sound generated and received is measured with a sound level meter. The background noise level is also measured. The higher the background noise then the higher the source noise will need to be set, since the resulting noise level in the receiver room needs to be 10dB higher than the background noise at all measured frequencies. 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 variations or differences in noise level are ‘corrected’ to take into consideration the already present background noise in the receiving room and the reverberation time – measure of time needed for a sound to decay or be absorbed in a closed room by 60dB. Impact tests are done by placing a standardised tapping machine on the floor. The noise level is then recorded in the room below. Calculations based on these measurements are undertaken and the results compared to the Building Regulations Part E requirements for the given type of the building. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.
What Sound Insulation Testing Equipment do we use?
The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. 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 administered in room with residential purposes. For example, kitchens/living spaces, lounges, bedrooms and living rooms. Test findings are compiled in a report and issued to the client. The report will be accepted by Building Control and used for signing off your project.
These kinds of properties should undergo a sound insulation test:
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 2 or more dwellings
This makes sure that the sound insulation for the building meets all the necessary requirements.
Conversions of former single dwelling properties into flats
The development that has been converted must conform to Building Regulations sound requirements.
Designed in a way that does not adhere to Robust Details
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 building design does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building Regulations. A building built as a permanent dwelling has different minimum standards from a building with rooms built for residential purpose, like a hotel or a hostel.

Airborne and impact ceilings/floor tests
The ceilings/floors of developments undergo impact and airborne floor testing. An impact test examines the level of noise moving from one dwelling to another through impact on adjoining floors/ceilings. The adjoining floors/ceilings of rooms intended as residences usually have both impact and airborne sound tests.
Our sound insulation testing in accordance with Building Regulations Approved Document E, which sets out details pertaining to the resistance to the passage of sound. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw for new structures. Converted properties get a slightly different requirement. Expected minimum airborne sound insulation test result is 43dB DnTw+Ctr while expected maximum impact sound test result is 64dB L’nTw.

Part E of building regulations 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.
Building Standards Division (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 taken at the completion of the building, using procedures given in annex 5.C. of the Scottish Standards. These standards don’t apply to detached structures that have access only for maintenance or are to used only by the occupants who live below.
How to get a pass certificate for your sound test
The most efficient way to make sure you pass sound insulation test is to have a plan that puts sound insulation into consideration from the begining. You don’t have to spend too much for this and it will save you money in the long run, ensuring you don’t pay remedial or re-test expenses. 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 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 fitted and sealed Light switches, plug sockets, and light fittings are adequately fixed. Our expert acoustic consultants work with planners, developers, architects and contractors from the beginning of the design stage till when the property is finished to ensure it meets the conditions of Document E 2003.
Test 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.
How the results are
A sound insulation certificate will be sent to you whether the property has a good sound performance in accordance with ADE or not. If a partition wall or floor does not comply with Part E standards, repair work and another sound test will be needed. We can give robust advice on that to ensure you pass.
