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 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 pride ourselves on issuing our sound insulation testing certificates as quickly as possible.
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.

How Sound Testing Works
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 part of 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. 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 dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
After the test, the sound insulation test engineers will let you know the outcome of the test and supply simple feedback of important things noted during the test; e.g. problems that might occur in the future.
The entire report and individual sound test certificate will be sent to you the day after. 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). Buildings to be tested are categorised into three kinds: houses, flats and rooms like care homes, student accommodation and hotel rooms. How much testing that should be done on each group is listed below:
Why is Sound Insulation Testing Required? Why is it Important?
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. 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 having privacy while speaking are crucial for a number of reasons. When sound insulation is deficient, it can cause discomfort to occupants. Let’s take a look at this scenario. An individual living in a block of flats might spend the weekend with friends relaxing and playing loud music. If the sound insulation on adjoining walls and floor is insufficient, the music will be distressful to neighbours, especially if they work at night. 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?
Your development needs a sound insulation test if it meets one of the following criteria:
- It’s design does not have Robust Details
- It’s a new building with 2 or more dwellings
- It’s being constructed to be used as a residence, like a hotel room or a hostel, or as a nursing home
- It was once a single dwelling but is being turned into a development with several flats or units.
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. When you use it, you don’t have to take a sound insulation test. However, you must abide strictly by the design from the Robust Details approved list. Being able to adapt your design to suit your needs is more efficient and costs less in the long run. On-site pre-completion sound insulation testing gives architects more insight and ability to make their design lead to constructions that have a higher sound performance.

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. 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.
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. We carry out airborne and impact tests on separating floors, and airborne tests on separating walls.
A big or multidirectional speaker, with a generator of pink or white noise is used to the biggest room. 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. Airborne sound tests are conducted in this manner: two singular speaker positions are used for every source room. The noise in the receiver room is measured to determine the variations in noise level between the source and receiver 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 tests are carried out by means of a tapping machine placed on the floor to be measured. The sound level in the room below it is recorded. This is used in calculating and computing the results. These results are checked against Building Regulations ADE conditions for that kind of dwelling. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.
What Sound Insulation Testing Equipment do we use?
Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. 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. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. Testing is done on rooms that can be lived in. E.g. lounges, kitchens, bedrooms and living rooms. You will get the test results in a report within a working day. This report can be used to help sign off your building as it is accepted by Building Control.
These kinds of properties should undergo a sound insulation test:
Sound Insulation Testing checks for both airborne and impact noise travelling through new or existing buildings. This may affect party walls and floors between new and existing buildings, or between spaces within a new development.
A structure with 2 or more units/flats
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Conversions of former single dwelling properties into flats
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Design not using Robust Details
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 building design does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building Regulations. The minimum requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.
