The measurement of the sound reduced by partitions in a development, such as a wall or floor, is known as sound insulation testing or sound testing. It assesses how good the soundproofing materials fixed to the property development are. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo 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. 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.
AF Acoustics’ competent and well-trained engineers, who will be available for testing, can even let you know the verbal results of your sound test. You will receive a written report in the space of a 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. 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. Sound insulation testing varies by size, complexity and conditions of site tested. A dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
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. 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 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. 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. When sound resistance is high in party walls and floors, the environment is more comfortable, since sound affects every aspect of our lives – work environment, home environment and while relaxing. This is why sound testing is crucial.
Sound insulation and speech privacy are important because not having them results in an unfavourable environment for those living in the development. 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. Sound insulation is also effective in buildings that have flats with mixed uses. If the building passed the sound test, you can be sure that noise reduction will be effective.
Do I Need a Sound Insulation Test?
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
Building Regulations Part E discusses sound testing in detail and has made it a requirement.
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. If you choose the latter, you must use Robust Details which are a approved design details for partitioning walls and floors. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. Being able to adapt your design to suit your needs is more efficient and costs less in the long run. 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?
We can undertake your sound tests when your building has almost been completed. By this time, you should have fixed internal and external doors and windows. We can conduct sound tests beforehand if required. 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.
How is Sound Insulation Testing Done?
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. We carry out airborne and impact tests on separating floors, and airborne tests on separating walls.
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. A sound level meter calculates the noise in the source room and receiver room. Background sound is also calculated. Noise in the receiver room should be 10dB more than the background noise at all frequency measurements, so source noise is set to be greater than background noise. 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 sound tests are performed with a tapping machine positioned on the floor of the source room. Noise level in the room below is measured at various different frequencies. 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.
Kind of Testing Equipments Used
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. The calculation of the level of noise transmitted through the air between two adjoining units is known as an airborne sound insulation test. Equipment used for the test include a noise generator, speakers and sound level meter. We use a tapping machine, which drops metal hammers onto the floor to create impact noise. We then measure the amount of sound that passes through the partition with a sound level meter in the room under the tapping machine. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. 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.
These kinds of properties should undergo a sound insulation test:
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.
A new building with not less than two rooms
With the sound test, you can be certain that the property has a good acoustic performance.
Conversions of former single dwelling properties into flats
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
Design that don’t have Robust Details factored in
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 design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. 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 for floors/ceilings
The ceilings/floors of developments undergo impact and airborne floor testing. An impact test measures the levels of noise transmitted directly through a separating construction. These floors in habitable rooms of flats undergo both impact and airborne tests.
Approved 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. For new buildings, results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. Converted structures expected impact sound results increases by 2dB L’nTw while the airborne sound results reduces by 2dB DnTw+Ctr.
We want to give our customers the most highest chance to acquire a pass and via our offer skilled services. In new build properties an airborne test or an airborne and impact test may be required to ensure it meets the requirements of greater than 45dB DnTw+Ctr and less than 62dB L’nTw. We regularly offer consultations to builders and project managers at the beginning of the development, so that they can take the appropriate action and are confident when it’s time to take the sound insulation test.

Building regulations document E 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 explicitly describes expected energy performance of dwellings. It 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.” 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 get a pass certificate for your sound 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. Whether you want some initial tests on your project, or comprehensive reports at the end, we can help you at the level that you need. The following will give you a better chance of passing the sound test: Inner and outer doors and windows have been installed and can be used Fit and seal skirting boards Light switches, plug sockets, and light fittings are adequately fixed. 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 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.

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 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.
