Sound testing rates the amount of sound the soundproofing insulation installed in a building for reduction of sound. It checks the amount of sound transmitted and the amount reduced by the building’s partitions. Part E of Building Regulations requires sound insulation in buildings and mandates that all newly completed constructions and rehabilitated developments go through sound testing.
As many contractors and developers have found to their detriment, without a sound insulation certificate, the Building Control Officer will not issue a completion certificate. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. When the tests are completed, we work quickly to issue your certificates; we take great pride in our efficiency.
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 insulation tests examine airborne and impact sound moving between separating walls and floors. The tests include party walls and floors between structures or between spaces within a new 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. Sound insulation testing varies by size, complexity and conditions of site tested. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.
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 full report and individual sound test certificates can be generated and sent out the next day. The sound testing guidelines are stipulated in Building Regulations ADE. It requires one set of test to be conducted on 10 units in a group or sub-group. You can find out what is meant by a sub-group in Section 1 of ADE. Buildings to be tested are categorised into three kinds: houses, flats and rooms like care homes, student accommodation and hotel rooms. Find below the testing stipulation for each kind of development.
Why Should Your Dwelling Undergo Sound Testing
Document E of Building regulations, from 2003, made it compulsory for all new UK constructions to undertake a pre-completion sound test. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. This Approved Document, as part of UK Building Regulations helps to ensure that new buildings are constructed to minimum standards that provide reasonable resistance to sound from other parts of the same building and from 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.
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 just one example of how sound insulation can affect the quality of life of people in different 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?
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.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. Robust Details are design details for separating elements, which have been tested before to comply with Document E standards. The Robust Details scheme means that testing is not necessary, but is strictly limited to the design given in the Robust Details approved list. 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. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.
Price for Sound Insulation Testing
We can send quotation that’s completely free of charge and is based on the kind of development you have. We have handled all kinds of sound insulation projects in UK and issue a report and certificate as quickly as possible. Our prices are affordable too and can beat others.
Ideal Period for a Sound Insulation Test
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.
How is Sound Insulation Testing Done?
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. The boundary floors and walls get airborne tests. Floors get an additional impact test.
A pink or white noise generator and a large speaker is used for the test in the biggest room between the two undergoing testing. A sound level meter is then used to take noise measurements within the source room and the receiver room. Background noise is measured to make certain that the source noise is greater. This way the standard of the receiver room having a 10dB higher noise level at all calculated frequencies can be realised. Airborne sound tests are conducted in this manner: two singular speaker positions are used for every source room. The noise in the receiver room is measured to determine the variations in noise level between the source and receiver room.
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. Noise level in the room below is measured at various different frequencies. Calculations based on these measurements are undertaken and the results compared to the Building Regulations Part E requirements for the given type of the building. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.
Type of Sound Insulation Test Machines We Will be using
You can expect UKAS calibrated equipment from us, as stipulated by Building Regulations. Our certified engineers conduct tests to meet the current guidelines. The calculation of the level of noise transmitted through the air between two adjoining units is known as an airborne sound insulation test. 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. Testing is done on rooms that can be lived in. E.g. lounges, kitchens, bedrooms and living rooms. 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 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.
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
The development that has been converted must conform to Building Regulations sound requirements.
Using designs where Robust Details are not included
The Robust Detail Scheme, set up in 2004 by Robust Details Ltd, architects create design details for walls and floors that were tested formerly for sound insulation and meet the sound performance parameters stated by Part E of Building Regulations. Once the design does not strictly abide by the design from Robust Detail approved list, the structure will have to undergo a sound test to ensure it conforms to Building 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.

Impact and airborne floor test
These are taken on separating floors/ceilings between residences. 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.
PART E Testing
AF Acoustics sound testing adheres to ADE which stipulates information bearing on the sound resistance and performance of a property. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result for newly completed constructions. On the other hand, 64dB L’nTw or less impact sound and 43dB DnTw+Ctr or higher airborne sound insulation is expected from refurbished buildings.
Testing for sound insulation
Our services and expertise is unbeatable and we are glad to work with our clients to help pass their sound insulation tests. 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.

Building regulations document E resistance to the passage of sound (England and Wales)
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.
Standard division for developments (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.” 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.
Passing a sound insulation 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 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 are required in order to have good conditions to undertake the sound insulation tests: Inner and outer doors and windows have been installed and can be used Skirting boards are fixed Light switches, light fittingsand plug sockets are properly fitted Our experienced acoustic consultants work with developers, contractors, architects and planners of all sizes from the early design stage to help minimise any potential issues right through to project completion, ensuring that all properties are compliant with Building Regulations Document E 2003.
Certificates for test evaluation and report
After the test, AF Acoustics’ competent and well trained engineers can let you know the verbal results of your sound test and provide feedback on issues noticed during the test. We endeavour to send an investigation and report certificate the next working day. 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 issued whether the Sound Testing results and report indicate compliance with Part E of the 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.
