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 has been a mandatory part of the Building Regulations for new build and refurbishment projects since Approved Document E (ADE) was revised in 2003.
At the completion of the test, a sound insulation certificate is issued. Without the certificate, Building Control will not release the building completion certificate to the contractors and developers of the project. We understand how important it is for you to get a sound insulation certificate. That’s why we go the extra mile to make sure you get your certificate as quickly as possible. We pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.
Our fully trained sound insulation test engineers can be on site when you need them. Your AF Acoustics engineer will give you immediate verbal results from the sound test, and you can will have a written report by the following working day.

What is a Sound Insulation Test?
In order to comply with Part E of the Building Regulations, developments will require the testing of separating walls and floors. The only exception is where Robust Details have been 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
A sound insulation test creates a high amount of noise but needs a site with low noise levels to be taken effectively. As a result of this, workers in a testing area might have to leave the development temporarily, so that the test can be free from errors. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.
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. The sound insulation testing methodology has been outlined by Document E of the Building Regulations. The document states that every 10 units in a sub-group or group should undergo one set of test, and defines a sub-group in Section 1. ADE goes on to define and group the type of structures that will undergo testing. They are houses, flats and rooms that are being used or are planned to be used as residences; such as student accommodation, care homes and hotel rooms. The volume of testing carried out on each group is written below.
Why Should Your Dwelling Undergo Sound Testing
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. 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.
Sound insulation and speech privacy are important because not having them results in an unfavourable environment for those living in the development. It would mean noise moving from one flat to another in a block of flats. If, for example, an occupant works at night and happens to hear loud music from a neighbour upstairs on a weekend night, it would be very discomforting. This is one way sound insulation can affect how a person 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.
How Do I Know if I Need a Sound 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. ADE thoroughly explains sound testing and makes it compulsory.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. 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. The Robust Details scheme means that testing is not necessary, but is strictly limited to the design given in the Robust Details approved list. Sound testing provides more flexibility by allowing different designs and is often therefore more cost effective in many ways compared to the Robust Details Scheme. Conducting on-site pre-completion sound testing also enables the architects more scope with their design and can lead to improved sound insulation performance.

When Should the Sound Tests be done?
A sound test is usually conducted just before the construction is completed, and when all the doors and windows have been fixed. However, we can test your building earlier to check for 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 a Sound Test is 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. We carry out airborne and impact tests on separating floors, and airborne tests on separating walls.
The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. The sound in the source room and receiver room (sharing a separating wall with the source room) 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. 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. 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. Once the calculations are completed and the result is achieved, it is compared with Building Regulations Part E standards. Of course, this is a simple way of describing the procedure followed when a sound test is carried out, but it enables you to understand it better.
Kind of Testing Equipments Used
You can expect UKAS calibrated equipment from us, as stipulated by Building Regulations. Our certified engineers conduct tests to meet the current guidelines. An airborne sound test measures levels of sound transmitted through the air through a separating element. Equipment used for the test include a noise generator, speakers and sound level meter. A sound level meter and a tapping machine which drops metal hammers is used for impact testing. 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.
These kinds of properties should undergo a sound insulation test:
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.
A new building with not less than two rooms
This makes sure that the sound insulation for the building meets all the necessary requirements.
Converting a property into several units
When the development is completed, ADE of Building Regulations should be checked, and sound insulation tested accordingly.
Designed in a way that does not adhere to Robust Details
The Robust Details scheme was set up in 2004 by Robust Details Ltd as a way to help architects and builders design and construct separating elements with the confidence that the separating wall and/or floor will be capable of achieving the sound performance parameters in Approved Document E, and comply with the Building Regulations. If the building design is slightly different from Robust Details, a sound test is essential so that Building Regulations criteria can be met. 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.

Scotland Standard division for completed constructions
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.” 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.
Passing a sound insulation test
Make sure you pass your sound test by having efficient sound insulation included in the building design. It saves time and money and helps you avoid repair work and re-test expenses. We offer design services to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. Our consultation may include several site visits and thorough design reports, or more basic initial tests on your structure. The following will give you a better chance of passing the sound test: Windows and internal and external doors are fitted and operable Skirting boards are fixed are sealed Plug sockets, light switches and fittings are in place and working. 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.
