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. Part E of Building Regulations requires sound insulation in buildings and mandates that all newly completed constructions and rehabilitated developments go through sound testing.
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. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. When the tests are completed, we work quickly to issue your certificates; we take great pride in our efficiency.
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?
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 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 involved in Sound testing?
Workers on a site will vacate the premises while the sound test is being conducted. This will facilitate an enabling and quiet environment for the tests to be carried out. 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 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 full report and individual sound test certificates can be generated and sent out the next day. 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. 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. Find below the testing stipulation for each kind of development.
Why Sound Testing is Required
After the 2003, Approved Document E mandates that all new structures in UK must take a sound insulation test before completion. Results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. This Approved Document, as part of UK Building Regulations helps to ensure that new buildings are constructed to minimum standards that provide reasonable resistance to sound from other parts of the same building and from adjacent buildings. 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.
There are so many more reasons why sound insulation and speech privacy are vital. An inefficient sound insulation treatment will lead to uneasiness for the inhabitants of the dwelling. For instance, an inhabitant in an apartment building sleeps during the day and works at night all the days of the week. If the neighbour in the upstairs flat has friends over and plays loud music, without a good sound insulation system, the working occupant will be uncomfortable and uneasy. This is just one example of how sound insulation can affect the quality of life of people in different ways. It can be useful in dwellings with neighbouring units/flats/rooms which have diverse purposes, by guaranteeing that an occupant in a room will hear as little noise as possible from the neighbouring room.
Does Your Development Need a Sound Insulation Test?
You need sound insulation testing if you:
- Build a new development of 2 or more dwellings / flats
- Convert a former single dwelling into flats
- Build a Nursing Home or rooms for residential use, i.e. hotel or hostel
- Have designs which do not adhere to Robust Details
Document E of the Building Regulations explains sound insulation testing and makes it a necessity.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. Robust Details are design details for separating elements, which have been tested before to comply with Document E standards. Using Robust Details, without taking a test, limits you to the design you’ve picked. 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?
We can undertake your sound tests when your building has almost been completed. By this time, you should have fixed internal and external doors and windows. We can conduct sound tests beforehand if required. During the test, you should provide the following:
- Access to all rooms. The only exception is if a schedule was created before the test time.
- 240V power supply
- A noiseless site
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. The separating walls undergo airborne tests while separating walls and floor undergo 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. A sound level meter is then used to take noise measurements within the source room and the receiver room. Noise in the background is also calculated. More noise in the background means a higher level of source sound will be created since it’s supposed to be 10dB higher than background noise on all calculated frequencies. 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.
The variations or differences in noise level are ‘corrected’ to take into consideration the already present background noise in the receiving room and the reverberation time – measure of time needed for a sound to decay or be absorbed in a closed room by 60dB. Impact tests are conducted by fixing a tapping machine on the floor. Noise level in the room below is measured at various different frequencies. Calculations based on these measurements are undertaken and the results compared to the Building Regulations Part E requirements for the given type of the building. 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
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. Airborne sound test is the measurement of sound moving through the air through a wall or floor. We use a loudspeaker and noise generator that produces white or pink noise on one side of the partition, and measure with a sound level meter on both sides to calculate the sound insulation performance of the partition. 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. 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.
Sound insulation testing is essential for these dwelling types:
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.
A structure with 2 or more units/flats
This makes sure that the sound insulation for the building meets all the necessary requirements.
A single dwelling that was turned into a development with several flats or units
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
Using designs where Robust Details are not included
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 slightly different from Robust Details, a sound test is essential so that Building Regulations criteria can be met. 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).
