The measurement of the sound reduced by partitions in a development, such as a wall or floor, is known as sound insulation testing or sound testing. It assesses how good the soundproofing materials fixed to the property development are. Part E of Building Regulations requires sound insulation in buildings and mandates that all newly completed constructions and rehabilitated developments go through sound testing.
Building Control does not issue completion certificates to buildings that don’t have a sound insulation certificate. Contractors and developers have sometimes discovered this, to their detriment. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. When the tests are completed, we work quickly to issue your certificates; we take great pride in our efficiency.
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 Sound Insulation Testing Does
Developments must test all walls, floors and ceilings that separate buildings or neighbours in a dwelling, to conform to Approved Document E (ADE) of the Building Regulations. You may not have to test your building if you used Robust Details which were approved before their installation. 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.
The Procedures Involved in a Sound Insulation Test
The sound test itself produces very high levels of noise but also requires relatively quiet conditions on site. For these reasons, any workforce in the testing area will have to leave temporarily to ensure test accuracy. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.
Once this is done, the sound test engineers give temporary results while they’re still on the site. They will also provide suggested solutions to possible problem areas noted during testing.
A full and thorough report with the certificate of the test will be given to you within 24 working hours. Every 10 units in a group or sub-group are to be tested, according to ADE. A sub-group is stipulated in Section 1. Of ADE ADE goes on to define and group the type of structures that will undergo testing. They are houses, flats and rooms that are being used or are planned to be used as residences; such as student accommodation, care homes and hotel rooms. The extent of testing required for these three groups is shown 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. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. 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.
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. 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. This is one way sound insulation can affect how a person lives. 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.
Do You 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.
Document E of the Building Regulations explains sound insulation testing and makes it a necessity.
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 separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. 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. Being able to adapt your design to suit your needs is more efficient and costs less in the long run. Conducting on-site pre-completion sound testing also enables the architects more scope with their design and can lead to improved sound insulation performance.

Sound Insulation Test Time
A sound test is usually conducted just before the construction is completed, and when all the doors and windows have been fixed. However, we can test your building earlier to check for problems. 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.
How is Sound Insulation Testing Done?
The method of taking the test is not complex and our sound test engineers can explain it thoroughly on site, if you wish. 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. The noise from the source room and received by the receiver room, and background noise is measured with a sound level meter. The background noise level is also measured. The higher the background noise then the higher the source noise will need to be set, since the resulting noise level in the receiver room needs to be 10dB higher than the background noise at all measured frequencies. For airborne tests, two speakers positions are used in the source room and the level of noise entering into the receiving partition room is measured. That way the difference in sound level is calculated.
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 pressure level at the receiving room, which is below the source room, is measured. 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 licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. An airborne test is used to check how much sound is moving through the air between partitions. Equipment used for the test include a noise generator, speakers and sound level meter. A sound level meter and a tapping machine which drops metal hammers is used for impact testing. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. 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.
Sound insulation testing is essential for these dwelling types:
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.
Two or more new build dwellings or 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
When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.
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. Minimum criterion differs based on the type and purpose of the development. A development with rooms intended as residences, like a hostel or hotel, won’t have the same criteria as a structure for permanent dwelling.

Scotland Standard division for properties
Section 5.1 of the Scottish Building Standards explicitly describes expected energy performance of dwellings. It 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 performed after construction, using the procedures given in annex 5.C. of the Scottish Standards. Standard 5.1 does not apply to: fully detached houses or roofs or walkways with access solely for maintenance, or solely for the use of the residents of the dwelling below.
How to make sure you pass your sound 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. We offer design services that help you construct separating walls and floors with good sound performance that meet ADE demands. Our consultation may include several site visits and thorough design reports, or more basic initial tests on your structure. The following criteria should be followed to provide you with the best chance of passing your sound test: Windows and internal and external doors are fitted and operable Skirting boards are fixed are sealed Fix all light switches, light fittings and plug sockets. We work with several professionals in construction from the beginning of the design stage to the completion of the development to make certain it conforms to Document E 2003 of Building Regulations.
Test 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.
