Sound testing rates the amount of sound the soundproofing insulation installed in a building for reduction of sound. It checks the amount of sound transmitted and the amount reduced by the building’s partitions. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo sound testing.
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. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
Our highly qualified site engineers can arrive on site when needed. They will provide verbal results after the test and a written report will be sent to you within 24 working hours.

What is a Sound Test?
To completely fulfil Building Regulations Part E requirements, the separating walls and floors of dwellings will be tested, unless approved Robust Details are 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 involved in a Sound 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. Sound insulation testing varies by size, complexity and conditions of site tested. Most of the time the test will be conducted in 90 minutes, for a simple, regular sized construction.
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.
You will get a detailed written report and sound test certificate about a day after, if possible. 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 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. How much testing that should be done on each group is listed below:
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. 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. 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 critical for a variety of reasons. Inadequate sound insulation can be extremely distressing to those affected by it. 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. Sound insulation is also effective in buildings that have flats with mixed uses. If the building passed the sound test, you can be sure that noise reduction will be effective.
How to Know if You Need Sound Insulation Testing
You need a sound insulation test if you’re:
- Constructing a nursing home or residential rooms like hostel or hotel rooms,
- Converting a building with a single dwelling into flats,
- Constructing a property with two or more units,
- Using designs without Robust Details to build
It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
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. 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 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.

Period Sound Insulation Test Should be Carried Out
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. 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 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.
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. Background noise is measured to make certain that the source noise is greater. This way the standard of the receiver room having a 10dB higher noise level at all calculated frequencies can be realised. 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.
The sound difference is adjusted to make an allowance for reverberation time (time in which the sound decays by 60dB) and background noise in the receiver room. Impact tests are done by placing a standardised tapping machine on the floor. The noise level is then recorded in the room below. 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 a simple way of explaining how a sound test is conducted.
Type of Sound Insulation Test Machines We Will be using
Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. The calculation of the level of noise transmitted through the air between two adjoining units is known as an airborne sound insulation test. 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. The tests are administered in room with residential purposes. For example, kitchens/living spaces, lounges, bedrooms and living rooms. 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 testing measures the impact and airborne sound moving through new and old adjoining buildings. This could affect the separating walls between buildings or in-between the spaces in a development.
Property with two or more units
This makes certain that the dwellings have adequate sound proofing.
Conversions of former single dwelling properties into flats
When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.
Design not using Robust Details
Robust Details Ltd began the Robust Details scheme in 2004. The scheme enables architects use design details for separating elements, which have been tested before to comply with Document E standards. Once the design does not strictly abide by the design from Robust Detail approved list, the structure will have to undergo a sound test to ensure it conforms to Building Regulations. The minimum criterion is based on various factors such as the purpose of the development and if it is a permanent dwelling or rooms to be used as residences like students’ accommodations and hotels.

Impact and Airborne floor test
These are performed on floors and/or ceilings between units. The calculation of the sound level transferred from one unit to another through a separating floor via impact is called an impact test. Airborne and impact tests are conducted on the floor partitions between liveable rooms.
PART E Testing
Document E of Building Regulations requires certain criteria for the sound performance of a dwelling. Our sound insulation tests are conducted in accordance to these criteria. For new buildings, results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. Converted structures expected impact sound results increases by 2dB L’nTw while the airborne sound results reduces by 2dB DnTw+Ctr.
Sound Insulation Testing
We offer the highest levels of service and expertise and are always happy to work with you to give you the best possible chance of achieving a pass certificate.

Part E of building regulations resistance to the passage of sound (England and Wales)
Our certified engineers can come to your building whenever it might suit you to undertake sound insulation testing to Part E of Building Regulations adherence, recognised by Building Control.
Scotland Standard division for properties
Section 5.1 of the Scottish Building Standards 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 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.
Passing a sound insulation test
The most efficient way to make sure you pass sound insulation test is to have a plan that puts sound insulation into consideration from the begining. You don’t have to spend too much for this and it will save you money in the long run, ensuring you don’t pay remedial or re-test expenses.
