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.
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 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. In fact, we pride ourselves on issuing our sound insulation testing certificates as quickly as possible.
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 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 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 Sound Insulation Testing
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. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.
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.
The entire report and individual sound test certificate will be sent to you the day after. The sound testing regime is set out in the Approved Document E of the Building Regulations. It states that one set of tests is required for every 10 units in a group or sub-group. Sub-groups are defined in Section 1 of Approved Document E (ADE). 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 is Sound Insulation Testing Relevant?
After the 2003, Approved Document E mandates that all new structures in UK must take a sound insulation test before completion. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. 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.
Insufficient sound insulation causes distress and comfort while an effective sound insulation system brings about speech privacy. This is one of the several reasons why sound insulation is a key element in building. 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. 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.
How to Know if You Need Sound Insulation Testing
Your development needs a sound insulation test if it meets one of the following criteria:
- It’s design does not have Robust Details
- It’s a new building with 2 or more dwellings
- It’s being constructed to be used as a residence, like a hotel room or a hostel, or as a nursing home
- It was once a single dwelling but is being turned into a development with several flats or units.
Sound insulation is covered and made mandatory under Approved Document E of The Building Regulations.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. Robust Details are a set of specific design details for walls and floors that have been previously tested to show compliance and must be used if this route is selected. 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 insulation testing is a more flexible approach. You can pick from a plethora of designs, as opposed to Robust Details. 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
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. 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.
The Procedures of a Sound Insulation Test
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.
A big or multidirectional speaker, with a generator of pink or white noise is used to the biggest room. A sound level meter is then used to take noise measurements within the source room and the receiver room. 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. For airborne tests, two speakers positions are used in the source room and the level of noise entering into the receiving partition room is measured. That way the difference in sound level is calculated.
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. A tapping machine is placed on the floor to execute an impact sound insulation test. The sound pressure level at the receiving room, which is below the source room, is measured. Once the calculations are completed and the result is achieved, it is compared with Building Regulations Part E standards. This is a simple way of explaining how a sound test is conducted.
Kind of Testing Equipments Used
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.
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.
Property with two or more units
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Converting a single development to flats
The development that has been converted must conform to Building Regulations sound requirements.
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 is not in line with any Robust Details, it will require sound testing to ensure its compliance with the buildings 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).

Airborne and impact tests are conducted on the floor partitions between liveable rooms.
Document E test
Document E of Building Regulations requires certain criteria for the sound performance of a dwelling. Our sound insulation tests are conducted in accordance to these criteria. The impact sound test of new dwellings should be 62dB L’nTw or less and airborne sound insulation 45dB DnTw+Ctr or more while impact results for reconstructed properties should be 64dB L’nTw and airborne sound insulation 43dB DnTw+Ctr or more.
We want to give our customers the most highest chance to acquire a pass and via our offer skilled services.

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?
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. 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.
