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.
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. We know how important a sound insulation certificate is to you. That is why we work hard to make certain that you get the certificate quickly. We take great pride in providing our certificates to you as soon as possible after the tests.
Even before you get the certificate, you will receive the results of the test. First, our skilled and competent sound insulation test will engineers give you a verbal result at the site. Then, a written report is sent to you within 24 hours of a working day.

What Sound Insulation Testing Does
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 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.
The Procedures Involved in a Sound Insulation Test
Even though sound insulation testing equipment produces lots of noise, sound testing requires quiet conditions and dwellings. Because of this, workers on the site would have to leave during the time of the test, to avoid errors in the test calculation. The process of a sound test is determined by the size and complexity of the site being tested. Most of the time the test will be conducted in 90 minutes, for a simple, regular sized construction.
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.
A full and thorough report with the certificate of the test will be given to you 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. The extent of testing required for these three groups is shown below.
Why is Sound Insulation Testing Relevant?
Before completing a building, all new constructions should be tested for sound insulation, as stipulated by Approved Document E since 2003. New builds must achieve impact sound test results of no more than 62dB L’nTw and airborne sound insulation of no less than 45dB DnTw+Ctr. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same building. Testing for sound insulation is vital because sound influences how we live in the office, while relaxing or in the house. Restricting the sound that moves between floors and walls could result in a more relaxed and better surrounding.
Sound insulation and speech privacy are important because not having them results in an unfavourable environment for those living in the development. 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 instance of the influence of sound insulation on our lives. 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.
Does Your Development Need a Sound Insulation Test?
Are you converting your property into several units? Does your design not use Robust Details? Are you constructing a new building with more than two rooms? Are you building a nursing home or rooms that will used for residential purposes, like hotels and hostels? If so, your structure needs to undergo a sound test. Document E of the Building Regulations explains sound insulation testing and makes it a necessity.
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 design details for walls that were tested formerly and meet the sound performance parameters stated by Part E of Building Regulations. 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. It also gives architects the opportunity to evaluate their design and give your structure a much better sound insulation which will increase sound performance.

Ideal Period for a Sound Insulation Test
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. 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.
How is Sound Insulation Testing Done?
Sound testing procedure is quite simple and our engineers are happy to explain this on site. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.
The airborne sound insulation test is carried out with a large speaker or dodecahedron speaker, using a white or pink noise generator to create the source sound, almost always in the largest room of the two rooms under testing. 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. Airborne sound testing is done in a similar way. First, two speaker positions are used for each source room. Then, the level of sound in the receiver room is measured so that the difference in noise level between the two rooms can be calculated.
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 done by placing a standardised tapping machine on the floor. The sound pressure level at the receiving room, which is below the source room, is measured. 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.
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. Airborne sound test is the measurement of sound moving through the air through a wall or floor. 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 test, a tapping machine that makes impact sound by dropping metal hammers is used. A sound level meter is used to measure in the receiving room below the room the tapping machine is in. Testing is done on rooms that can be lived in. E.g. lounges, kitchens, bedrooms and living rooms. 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:
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
With the sound test, you can be certain that the property has a good acoustic performance.
Converting a single development to 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
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. 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 performed on floors and/or ceilings between units. Impact testing evaluates how much the sound flowing from one partition to another through party floors via impact is. Airborne and impact tests are conducted on the floor partitions between liveable rooms.
Approved Document E test
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.

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.
Scotland Standard division for properties
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.
How to get a pass certificate for your 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 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 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.
Analysis and Report Certificates
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 certificate will be issued to you whether the sound insulation treatment of the building meets the requirements of Document E of 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.
