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 has been a mandatory part of the Building Regulations for new build and refurbishment projects since Approved Document E (ADE) was revised 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. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
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?
Developments must test all walls, floors and ceilings that separate buildings or neighbours in a dwelling, to conform to Approved Document E (ADE) of the Building Regulations. You may not have to test your building if you used Robust Details which were approved before their installation. 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 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. The process of a sound test is determined by the size and complexity of the site being tested. If the site is simple and of regular size, it typically takes about 90 minutes to complete the sound test.
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. 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.
Importance of Sound Insulation Testing
Document E of Building regulations, from 2003, made it compulsory for all new UK constructions to undertake a pre-completion sound test. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. This is to be certain that all new developments meet a uniform minimum criterion for resistance to sound from other parts of the development and adjoining developments. Sound insulation testing is important because sound affects the way we live, whether at work, in the home or whilst at leisure. Noise reduction between walls and floors could result in a more comfortable, productive environment.
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 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 just one example of how sound insulation can affect the quality of life of people in different ways. There are also developments where the neighbouring units are used for different purposes. In such cases, a sound test ensures that the noise coming from each unit is minimal.
How to Know if You Need Sound Insulation Testing
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. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. With sound testing, however, you’re free to pick from any design, including more cost effective and appropriate ones. This makes it a more efficient process than Robust Details. On-site pre-completion sound insulation testing gives architects more insight and ability to make their design lead to constructions that have a higher sound performance.

When Should the Sound Tests be done?
The best time for a sound insulation test is just before the construction of the property is finished and after all windows and doors are fixed. However, in the case of a problem we can take the test before then. During the test, you should provide the following:
- Access to all rooms. The only exception is if a schedule was created before the test time.
- 240V power supply
- A noiseless site
The Process of a Sound Test
Sound testing procedure is quite simple and our engineers are happy to explain this on site. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. The sound generated and received 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. For airborne sound tests, two individual speaker positions are used for each source room. Measurements are then made to determine the levels in the receiving room of the tested partition in question. This gives a basic level difference between source and receiver rooms.
This basic level difference is then ‘corrected’ to allow for the reverberation time (the time is taken, in seconds, for a noise source to decay by 60dB) and the existing levels of background noise monitored whilst in the receiving room. Impact tests are conducted by fixing a tapping machine on the floor. The sound level in the room below it is recorded. This is used in calculating and computing the results. These results are checked against Building Regulations ADE conditions for that kind of dwelling. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.
Sound Test Equipment Used
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 calculates the amount of sound moving through a separating element. Equipment used for the test include a noise generator, speakers and sound level meter. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. 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 necessary for these types of builds:
The airborne and impact sound going through new and old buildings are evaluated by sound testing. This can impact adjoining walls and floors between the building.
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 development that has been converted must conform to Building Regulations sound requirements.
Designed in a way that does not adhere to 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 slightly different from Robust Details, a sound test is essential so that Building Regulations criteria can be met. 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).

Sound Insulation Testing Regulations
We provide sound testing and sound insulation testing on all types of buildings, for compliance with Part E Building Regulations in England and Wales and Section 5 of the Scottish Building Standards. Testing can also gain credits for Code for Sustainable Homes and EcoHomes environmental assessment schemes.
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 performed after construction, using the procedures given in annex 5.C. of the Scottish Standards. Standard 5.1 does not apply to: fully detached houses or roofs or walkways with access solely for maintenance, or solely for the use of the residents of the dwelling below.
How to pass a sound test
The most effective way to ensure you pass your sound test is to plan the project with sound insulation in mind. This does not need to be costly, and can save considerable time and expense at the end of the project, not to mention avoiding escalating remedial and re-test costs. 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 conditions will provide you with an ample chance of passing the sound test: All windows and doors have been fitted and work Skirting boards are fixed are sealed Light switches, light fittingsand plug sockets are properly fitted 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 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.
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 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.
