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 is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated in 2003.
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. When the tests are completed, we work quickly to issue your certificates; we take great pride in our 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 is a Sound Insulation Test?
To adhere to Building Regulations ADE requirements, adjoining walls, floors and ceilings in a building will have to be tested, except where licensed Robust Details were used. 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
A sound insulation test creates a high amount of noise but needs a site with low noise levels to be taken effectively. As a result of this, workers in a testing area might have to leave the development temporarily, so that the test can be free from errors. 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 complete report and sound insulation test certificate can be produced and issued within 24 working hours. The way a sound test is conducted is determined by ADE of Building Regulations. It mandates that in all developments, every 10 units in a group or sub-group will undertake one set of tests. It explicitly states what a sub-group is in Section 1. Buildings to be tested are categorised into three kinds: houses, flats and rooms like care homes, student accommodation and hotel rooms. How much testing that is required for each category can be found below.
Why is Sound Insulation Testing Relevant?
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. These result limits were put in to create and maintain a uniform standard for sound resistance in different parts of a dwelling and between adjacent buildings. 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.
There are so many more reasons why sound insulation and speech privacy are vital. An inefficient sound insulation treatment will lead to uneasiness for the inhabitants of the dwelling. For instance, an inhabitant in an apartment building sleeps during the day and works at night all the days of the week. If the neighbour in the upstairs flat has friends over and plays loud music, without a good sound insulation system, the working occupant will be uncomfortable and uneasy. Sound insulation impacts people’s lives in various 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.
Do I Need a Sound Insulation Test?
Are you converting your property into several units? Does your design not use Robust Details? Are you constructing a new building with more than two rooms? Are you building a nursing home or rooms that will used for residential purposes, like hotels and hostels? If so, your structure needs to undergo a sound test. It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
All you have to do is follow the guidelines listed in the document or pay to use Robust Details and you will have fulfilled the requirements. Robust Details are design details for separating elements, which have been tested before to comply with Document E standards. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. 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. It also gives architects the opportunity to evaluate their design and give your structure a much better sound insulation which will increase sound performance.

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.
The Process of a Sound Test
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 airborne sound insulation test is carried out with a large speaker or dodecahedron speaker, using a white or pink noise generator to create the source sound, almost always in the largest room of the two rooms under testing. 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 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. A tapping machine is placed on the floor to execute an impact sound insulation test. The sound level in the room below it is recorded. Once the calculations are completed and the result is achieved, it is compared with Building Regulations Part E standards. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.
Sound Test Equipment Used
The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. An airborne sound test measures levels of sound transmitted through the air through a separating element. Equipment used for the test include a noise generator, speakers and sound level meter. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. Test findings are fed into a report that will be sent to the client. This report will always be acceptable to Building Control and will help you to get your development signed off.
It’s important to undertake a sound test if you have this kind of building:
Sound testing measures the impact and airborne sound moving through new and old adjoining buildings. This could affect the separating walls between buildings or in-between the spaces in a development.
Two or more new build dwellings or flats
This makes certain that the dwellings have adequate sound proofing.
A single dwelling that was turned into a development with several flats or units
When the development is completed, ADE of Building Regulations should be checked, and sound insulation tested accordingly.
Design not using Robust Details
Robust Detail Ltd set up the Robust Detail Scheme in 2004 to make sure architect and building designs construct partition walls and floors that comply with Approved Document E sound insulation standards. 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. 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.

We can have fully accredited engineers sent to your property at your convenience to provide certification for Building Regulations Part E compliance, recognised by Building Control.
Scotland Standard division for completed constructions
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.” Fully detached roofs or walkways that are not used for residential purposes do not have to take the sound tests of the Scottish Standards 5.1.
How to pass a sound test
Make sure you pass your sound test by having efficient sound insulation included in the building design. It saves time and money and helps you avoid repair work and re-test expenses. If you’re not certain of how to construct your party walls and floors, to meet Document E 2003 targets, simply contact us for an efficient design service. Our consultation process is led by your project requirements and may include assessment of design reports, test of the development and multiple site visits. Take the following action to give your building the best opportunity to pass the sound insulation test: All windows and doors have been fitted and work Skirting boards are fixed Light fittings and switches and plug sockets are fitted and working. We work with several professionals in construction from the beginning of the design stage to the completion of the development to make certain it conforms to Document E 2003 of Building Regulations.
Test 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.
What do the results look like?
A certificate will be issued to you whether the sound insulation treatment of the building meets the requirements of Document E of Building Regulations or not. In the event that some part of the building does not meet up with the conditions of Document E, remedial work and a retest is required. We give remedial design advice to help you achieve Building Regulations standards.
