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. 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.
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. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. We pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.
Our highly capable sound test engineers will be available on site when you need them. They will give you a verbal result of the test, once taken and a written report will be issued to you by the following working day.

What Sound Testing Does
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 involved in a Sound Test
While producing lots of noise, sound test needs a quiet site to be conducted efficiently. Due to this fact, the workers in the site should not be present at the time of the test. Sound insulation testing varies by size, complexity and conditions of site tested. 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 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. ADE also states the categories of developments that should be tested. There are three: rooms, flats and houses (including bungalows) that are lived in. Examples are student accommodation, hotel rooms and care homes. The volume of testing carried out on each group is written below.
Why Should Your Dwelling Undergo Sound Testing
After the 2003, Approved Document E mandates that all new structures in UK must take a sound insulation test before completion. 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. 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 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.
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
It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
There are two ways in which to show compliance. You can either test to the regime set out in Approved Document E (ADE), or pay to use Robust Details. Robust Details are a set of specific design details for walls and floors that have been previously tested to show compliance and must be used if this route is selected. 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. 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
Ideally, we would conduct a test when a development nears completion, and once all internal and external doors and windows have been fitted. We can test earlier to check if there are any problems. 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.
How a Sound Test is Done
Sound testing procedure is quite simple and our engineers are happy to explain this on site. 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. A sound level meter is then used to take noise measurements within the source room and the receiver room. 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. 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.
This difference is modified to include background noise in the receiver room and reverberation time – time whereby a sound fades away in a closed space by 60dB. 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. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.
Kind of Testing Equipments Used
Our accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the building regulations. Airborne sound test is the measurement of sound moving through the air through a wall or floor. The equipment we use are a sound level meter, loudspeaker and white or pink noise generator. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. 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.
It’s important to undertake a sound test if you have this kind of building:
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.
Converting a property into several units
The development that has been converted must conform to Building Regulations sound requirements.
Designs without 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. 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.

Impact and Airborne floor test
These are taken on separating floors/ceilings between residences. The measurement of the extent of noise transmitted directly through impact from one adjoining room to another is known as impact testing. Airborne and Impact tests are carried out on the separating floors between habitable rooms of flats.
PART E Testing
Our sound insulation tests meet the requirements of Building Regulations Part E, which describes building structures resistance to the movement of sound within and from adjoining structures. The impact sound test of new dwellings should be 62dB L’nTw or less and airborne sound insulation 45dB DnTw+Ctr or more while impact results for reconstructed properties should be 64dB L’nTw and airborne sound insulation 43dB DnTw+Ctr or more.
We want to give our customers the most highest chance to acquire a pass and via our offer skilled services. To make sure a new residence meets with the standards of greater than 45dB DnTw+Ctr and less than 62dB L’nTw, an airborne wall test and an airborne and impact floor test will need to be conducted.

Resistance to the passage of sound: Approved Document E (England and Wales)
Our expert engineers can issue certificates for the sound insulation testing. They can visit the site and conduct the test that will lead to getting a certificate which is in line with Building Regulations and Building Control requirements.
Standard division for structures (Scotland)
In the words of 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.” The following are exempt from the testing techniques given in annex 5.C. of the Scottish Standard and Standard 5.1 – completely segregated rooftops, houses or walkways whose access is only used for upkeep or for the utilization of the inhabitants of the dwelling beneath.
Passing a sound insulation 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. We offer design services to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. We can study design reports, complete site visits and sound test the development to provide you with the level of assessment and consultation that your project requires from start to finish. The following will give you a better chance of passing the sound test: All windows and door have been fixed and are functioning Fit and seal skirting boards Plug sockets, light switches and fittings are in place and working. Our experienced acoustic consultants work with developers, contractors, architects and planners of all sizes from the early design stage to help minimise any potential issues right through to project completion, ensuring that all properties are compliant with Building Regulations Document E 2003.
Investigation and report certificates
To get details of the results of a completed sound insulation test, we will provide you with an analysis and report certificate. 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 sound insulation certificate will be sent to you whether the property has a good sound performance in accordance with ADE 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.
