Sound testing calculates the extent to which sound is blocked by the partition (walls, floors etc) of a building between dwellings. It evaluates the efficiency of the soundproofing materials that make up the structure. It is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated in 2003.
Not having a sound insulation certificate issued after a test, has resulted in additional costs and expenses for developers. Any development that has not taken a sound test will not be given a completion certificate by Building Control. Because we understand how the sound insulation certificate affects your building project, we ensure that you get it as quickly as possible after the test. In fact, we pride ourselves on issuing our sound insulation testing certificates as quickly as possible.
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 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.
The Procedures Involved in a Sound Insulation 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. A sound insulation test on a project is taken according to the scale and complexity of the construction and the conditions of the site. A dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
After the test, the sound insulation test engineers will let you know the outcome of the test and supply simple feedback of important things noted during the test; e.g. problems that might occur in the future.
You will get a detailed written report and sound test certificate about a day after, if possible. 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. 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. How much testing that should be done on each group is listed below:
Why Sound Testing is Required
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. The aim of Approved Documet E of the Building Regulations is to establish a minimum standard for the reduction in noise levels between all dwellings in a new or refurbished building. 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 having privacy while speaking are crucial for a number of reasons. When sound insulation is deficient, it can cause discomfort to occupants. 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. Then there are developments where each neighbouring room / flat / unit has mixed uses. If the development has passed the sound insulation test, noise is reduced to a minimum.
How Do I Know if I Need a Sound Test?
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.
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. 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. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. Sound insulation testing is a more flexible approach. You can pick from a plethora of designs, as opposed to Robust Details. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.

When can I carry out the sound insulation tests?
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. For your sound tests to be conducted successfully we need the property to be quiet, with workers not near the rooms to be tested during the test time (a noisy environment makes the test difficult and sometimes unsuccessful). We also need access to all units unless the test program has been compiled earlier. Finally, we need 240V power supply.
How is sound insulation testing carried out?
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.
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. 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. When conducting airborne sound insulation tests, two speakers are placed in each source room. The noise level in the receiving room is measured to get the sound difference between the source and receiving room.
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 pressure level at the receiving room, which is below the source room, is measured. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.
Type of Sound Insulation Test Machines We Will be using
Our accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the building regulations. An airborne test is used to check how much sound is moving through the air between partitions. A loudspeaker and noise generator is used in one room while a sound level meter is used in both rooms for measuring level of noise. 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 fed into a report that will be sent to the client. This report will always be acceptable to Building Control and will help you to get your development signed off.
It’s important to undertake a sound test if you have this kind of building:
For sound testing we usually undertake impact and airborne sound test on buildings. This affects the separating floors and walls between habitable rooms of buildings and developments.
Property with two or more units
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Converting a property into several units
When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.
Designed in a way that does not adhere to Robust Details
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. 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).

Impact and Airborne floor test
Impact and airborne floor tests are conducted on ceilings/floors between rooms. The calculation of the sound level transferred from one unit to another through a separating floor via impact is called an impact test. Airborne and impact tests are conducted on the floor partitions between liveable rooms.
Our sound tests align to Part E of Building Regulations guideline, which thoroughly describes sound resistance level and performance from structures. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw for new structures. Converted properties get a slightly different requirement. Expected minimum airborne sound insulation test result is 43dB DnTw+Ctr while expected maximum impact sound test result is 64dB L’nTw.

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 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 fixed are sealed 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.
Analysis and 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.
What do the results look like?
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 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.
