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. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo sound testing.
Not doing so is a costly venture for developers and contractors as Building Control will not give a completion certificate for developments that have not undergone the test. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. 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 is a Sound Insulation 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 measures the impact and airborne sound moving through new and old adjoining buildings. This tests include the boundary walls between buildings and in-between the spaces in a development.
What is involved in Sound testing?
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. 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.
After the sound insulation test, the sound testing engineer will provide provisional results whilst on-site, as well as providing basic feedback about what has been noted during the test, e.g. potential problems or any future areas of concern.
A complete report and sound insulation test certificate can be produced and issued within 24 working hours. Every 10 units in a group or sub-group are to be tested, according to ADE. A sub-group is stipulated in Section 1. Of ADE 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 is Sound Insulation Testing Required? Why is it Important?
From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. The impact sound test result should not be more than 62dB L’nTw and the airborne sound insulation should not be less than 45dB DnTw+Ctr. 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. 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
It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
There are 2 ways you can comply. Test for sound insulation using the method of Approved Document E or use Robust Details in your development. Robust Details are design details for separating elements, which have been tested before to comply with Document E standards. With it, you don’t need a sound insulation test, but you must completely follow every aspect of the design from the Robust Detail Approved list. This becomes difficult when you need to pick a more appropriate or cost-effective design that will suit your needs. Sound tests enable you do that, making it more flexible. 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.

When Should the Sound Tests be done?
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 Process of a Sound Test
Our sound test engineers can answer your questions and make the sound test process easy to understand on site, during the time of the test. 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. 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 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 carried out by means of a tapping machine placed on the floor to be measured. 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, this explanation highlights sound insulation testing procedures in a simple manner.
Type of Sound Insulation Test Machines We Will be using
Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. An airborne test is used to check how much sound is moving through the air between partitions. We use pink or white noise generator and speakers on one side of the partition. A sound level meter is used on calculating sound in both units. 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 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.
Sound insulation testing is essential for these dwelling types:
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.
Property with two or more units
This makes certain that the dwellings have adequate sound proofing.
Converting a single development to flats
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Using designs where Robust Details are not included
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 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).

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 properties
According to Section 5.1 of the Scottish Building Standards, “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.” The following are exempt from the testing techniques given in annex 5.C. of the Scottish Standard and Standard 5.1 – completely segregated rooftops, houses or walkways whose access is only used for upkeep or for the utilization of the inhabitants of the dwelling beneath.
How to make sure you pass your sound 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. We can study design reports, complete site visits and sound test the development to provide you with the level of assessment and consultation that your project requires from start to finish. 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 Skirting boards are fitted and sealed Plug sockets, light switches and fittings are in place and working. Our accomplished acoustic consultants work with developers, planners, contractors, and architects of all sizes from the early stages of the building plan to help limit any potential sound insulation performance problems to the completion of the construction, guaranteeing that all properties meet the criteria of Building Regulations Document E 2003.
Test and report certificates
To get details of the results of a completed sound insulation test, we will provide you with an analysis and report certificate. 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. In the event of a wall or floor not achieving the Part E requirements, it may be necessary to carry out remedial works before having another sound test carried out. We can provide you with remedial design advice to help you achieve the Building Regulations requirements.
