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. New structures and reconstructed developments have been mandated by the Building Regulations to test for sound upon completion, since Approved Document E (ADE) was reappraised 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. 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. When the tests are completed, we work quickly to issue your certificates; we take great pride in our efficiency.
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 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.
What is part of 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 way a sound test is administered depends on the size and type of building and the development’s condition. A structure that is simple and the conventional size will usually take 90 minutes to be tested.
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.
A complete report and sound insulation test certificate can be produced and issued within 24 working hours. The sound testing regime is set out in the Approved Document E of the Building Regulations. It states that one set of tests is required for every 10 units in a group or sub-group. Sub-groups are defined in Section 1 of Approved Document E (ADE). There are three types of grouping criteria that need to be assessed: dwelling houses (including bungalows), flats and rooms for residential purposes, such as student accommodation and hotel rooms, care homes etc. The volume of testing carried out on each group is written below.
Importance of Sound Insulation Testing
After the 2003, Approved Document E mandates that all new structures in UK must take a sound insulation test before completion. The impact sound test result should not be more than 62dB L’nTw and the airborne sound insulation should not be less than 45dB DnTw+Ctr. 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.
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. 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. 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.
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. Sound insulation is covered and made mandatory under Approved Document E of The Building Regulations.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. 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. 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. 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 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 achieve the best results we would need the following during the test: quietness during the time of the test, 240V power supply and access to all the rooms unless a test plan has been agreed upon prior to the test time.
The Procedures of a Sound Insulation Test
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
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. 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. For airborne sound tests, two individual speaker positions are used for each source room. Measurements are then made to determine the levels in the receiving room of the tested partition in question. This gives a basic level difference between source and receiver rooms.
Finally, the difference in noise level is modified to accommodate reverberation time and background noise that was already in the receiver room. Reverberation time is how long it takes sound to decay by 60dB. A tapping machine is placed on the floor to execute an impact sound insulation test. The noise level is then recorded in the room below. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
What Sound Insulation Testing Equipment do we use?
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. An airborne sound test measures levels of sound transmitted through the air through a separating element. The equipment we use are a sound level meter, loudspeaker and white or pink noise generator. 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 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.
These kinds of properties should undergo a sound insulation test:
Sound insulation tests examine airborne and impact sound moving through buildings. It is usually undertaken between party walls and floors between buildings or between spaces within a new development.
Two or more new build dwellings or flats
This makes certain that the dwellings have adequate sound proofing.
A single dwelling that was turned into a development with several flats or units
The development that has been converted must conform to Building Regulations sound requirements.
Using designs where Robust Details are not included
Robust Detail Ltd set up the Robust Detail Scheme in 2004 to make sure architect and building designs construct partition walls and floors that comply with Approved Document E sound insulation standards. If the design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. 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.

Standard division for structures (Scotland)
According to Section 5.1 of the Scottish Building Standards, “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 taken at the completion of the building, using procedures given in annex 5.C. of the Scottish Standards. These standards don’t apply to detached structures that have access only for maintenance or are to used only by the occupants who live below.
How to pass a sound test
All you have to do to pass your sound test is include adequate sound insulation in the design. That way, you save time and cost for repair work and re-test. If you’re not certain of how to construct your party walls and floors, to meet Document E 2003 targets, simply contact us for an efficient design service. Our consultation process is led by your project requirements and may include assessment of design reports, test of the development and multiple site visits. 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 expert acoustic consultants work with planners, developers, architects and contractors from the beginning of the design stage till when the property is finished to ensure it meets the conditions of 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
You will get your sound insulation test certificate whether you pass or fail the sound tests. 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.
