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 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. 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. 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 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 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 Sound Insulation Testing
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. If the site is simple and of regular size, it typically takes about 90 minutes to complete the sound test.
Once it is completed, the engineers will give a verbal interim result on the site and basic helpful information on what was noticed during the test, e.g. possible sound issues and future places that could cause problems.
The entire report and individual sound test certificate will be sent to you the day after. The way a sound test is conducted is determined by ADE of Building Regulations. It mandates that in all developments, every 10 units in a group or sub-group will undertake one set of tests. It explicitly states what a sub-group is in Section 1. 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. Find below the testing stipulation for each kind of development.
Why is Sound Insulation Testing Required? Why is it Important?
From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same 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 speech privacy are critical for a variety of reasons. Inadequate sound insulation can be extremely distressing to those affected by it. 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. Sound insulation impacts people’s lives in various ways. 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.
Do You 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. Sound insulation is covered and made mandatory under Approved Document E of The Building Regulations.
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 separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. Using Robust Details, without taking a test, limits you to the design you’ve picked. Sound insulation testing is a more flexible approach. You can pick from a plethora of designs, as opposed to Robust Details. 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 Should the Sound Tests be done?
The ideal period for a sound insulation test is after the fitting of windows and doors, and before the building is finished. If you want, AF Acoustics can conduct tests before then to find out if there are any problems on your property. 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.
The Process of a Sound Test
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.
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. The background noise level is also measured. The higher the background noise then the higher the source noise will need to be set, since the resulting noise level in the receiver room needs to be 10dB higher than the background noise at all measured frequencies. 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 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. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. This is a simple way of explaining how a sound test is conducted.
Sound Test Equipment Used
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. 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. A sound level meter and a tapping machine which drops metal hammers is used for impact testing. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. 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.
Sound Insulation Testing is necessary for these types of builds:
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.
Property with two or more units
This is to ensure that the sound proofing of the building is up to standard for residential purposes.
Converting a single development to flats
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
Design not using 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 does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building 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).

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.” 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.
How Do I Pass 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. Are you uncertain that the separating floor and walls you will build will adhere to Document E 2003 conditions? You can book our design services. 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 Fit and seal skirting boards Fix all light switches, light fittings and plug sockets. 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.
Certificates for test evaluation and report
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 usually 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.
The way the results look
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.
