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. Part E of Building Regulations requires sound insulation in buildings and mandates that all newly completed constructions and rehabilitated developments go through sound testing.
Building Control does not issue completion certificates to buildings that don’t have a sound insulation certificate. Contractors and developers have sometimes discovered this, to their detriment. We know how important a sound insulation certificate is to you. That is why we work hard to make certain that you get the certificate quickly. We take great pride in providing our certificates to you as soon as possible after the tests.
Our highly qualified site engineers can arrive on site when needed. They will provide verbal results after the test and a written report will be sent to you within 24 working hours.

What Sound Insulation Testing Does
To completely fulfil Building Regulations Part E requirements, the separating walls and floors of dwellings will be tested, unless approved Robust Details are used. Sound testing conducts impact and airborne sound test on structures. The tests include the separating floors, walls and areas between buildings within developments.
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. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. 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 report and individual sound test certificates can be generated and sent out the next day. 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:
Why Sound Testing is Required
Document E of Building regulations, from 2003, made it compulsory for all new UK constructions to undertake a pre-completion sound test. Results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. 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 speech privacy are critical for a variety of reasons. Inadequate sound insulation can be extremely distressing to those affected by it. It would mean noise moving from one flat to another in a block of flats. If, for example, an occupant works at night and happens to hear loud music from a neighbour upstairs on a weekend night, it would be very discomforting. 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.
How to Know if You Need Sound Insulation Testing
You need sound insulation testing if you:
- Build a new development of 2 or more dwellings / flats
- Convert a former single dwelling into flats
- Build a Nursing Home or rooms for residential use, i.e. hotel or hostel
- Have designs which do not adhere to Robust Details
ADE thoroughly explains sound testing and makes it compulsory.
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 separating elements, which have been tested before to comply with Document E standards. The Robust Details scheme means that testing is not necessary, but is strictly limited to the design given in 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.

Sound Insulation Test Time
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. For your sound tests to be conducted successfully we need the property to be quiet, with workers not near the rooms to be tested during the test time (a noisy environment makes the test difficult and sometimes unsuccessful). We also need access to all units unless the test program has been compiled earlier. Finally, we need 240V power supply.
How is Sound Insulation Testing Done?
The method of taking the test is not complex and our sound test engineers can explain it thoroughly on site, if you wish. 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. The noise from the source room and received by the receiver room, and background noise is measured with a sound level meter. The meter is also used to measure the background sound, to ensure that it’s 10dB lower than the source sound, as is the standard. More background sound leads to creating a higher source sound. Airborne sound tests are conducted in this manner: two singular speaker positions are used for every source room. The noise in the receiver room is measured to determine the variations in noise level between the source and receiver 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 sound tests are performed with a tapping machine positioned on the floor of the source room. The noise level is then recorded in the room below. Calculations are done and the outcome is checked against ADE requirements for the type of building. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
Sound Test Equipment Used
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of 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. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. Testing is done on rooms that can be lived in. E.g. lounges, kitchens, bedrooms and living rooms. 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.
It’s important to undertake a sound test if you have this kind of building:
Sound Insulation Testing checks for both airborne and impact noise travelling through new or existing buildings. This may affect party walls and floors between new and existing buildings, or between spaces within a new development.
Two or more new build dwellings or flats
This is to ensure that the sound proofing of the building is up to standard for residential purposes.
Redevelopment of a building with a single dwelling 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 building design is not in line with any Robust Details, it will require sound testing to ensure its compliance with the buildings regulations. The minimum requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.

Standard division for developments (Scotland)
Section 5.1 of the Scottish Building Standards states “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.
Passing a sound insulation 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 to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. Our consultation may include several site visits and thorough design reports, or more basic initial tests on your structure. The following conditions will provide you with an ample chance of passing the sound test: Install and make sure that all external and internal doors and windows are operational Skirting boards are fitted Plug sockets, light switches and fittings are in place and working. Our professional acoustic professionals work with contractors, architects, developers, and planner from the beginning of the design to make sure that all requirements are met.
Test and report certificates
To obtain a thorough evaluation of your building, we issue a report certificate within 24 working hours where possible. Our highly capable sound test engineers will give you a verbal result of the test, once the test is taken and proffer solutions to possible problems 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
You will get your sound insulation test certificate whether you pass or fail the sound tests. 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.
