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. New structures and reconstructed developments have been mandated by the Building Regulations to test for sound upon completion, since Approved Document E (ADE) was reappraised 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. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. We take great pride in providing our certificates to you as soon as possible after the tests.
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.

How Sound Testing Works
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 conducts impact and airborne sound test on structures. The tests include the separating floors, walls and areas between buildings within developments.
The Procedures Involved in a Sound Insulation Test
Even though sound insulation testing equipment produces lots of noise, sound testing requires quiet conditions and dwellings. Because of this, workers on the site would have to leave during the time of the test, to avoid errors in the test calculation. The process of a sound test is determined by the size and complexity of the site being 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 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. 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. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. The aim of Approved Documet E of the Building Regulations is to establish a minimum standard for the reduction in noise levels between all dwellings in a new or refurbished building. Sound insulation testing is important because sound affects the way we live, whether at work, in the home or whilst at leisure. Noise reduction between walls and floors could result in a more comfortable, productive environment.
Sound insulation and speech privacy are important because not having them results in an unfavourable environment for those living in the development. For example, in a block of flats, your upstairs neighbour may (and not unreasonably) like to have friends over at the weekend, resulting in the playing of loud music. However, the downstairs occupant may be working nights and sleeping throughout the day, thus any inadequate sound insulation between these two flats would cause great disturbance and distress to the downstairs occupant. This is just one example of how sound insulation can affect the quality of life of people in different ways. 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?
Are you converting your property into several units? Does your design not use Robust Details? Are you constructing a new building with more than two rooms? Are you building a nursing home or rooms that will used for residential purposes, like hotels and hostels? If so, your structure needs to undergo a sound test. ADE thoroughly explains sound testing and makes it compulsory.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. Robust details are separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. Using Robust Details, without taking a test, limits you to the design you’ve picked. Being able to adapt your design to suit your needs is more efficient and costs less in the long run. 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
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. For your sound tests to be conducted successfully we need the property to be quiet, with workers not near the rooms to be tested during the test time (a noisy environment makes the test difficult and sometimes unsuccessful). We also need access to all units unless the test program has been compiled earlier. Finally, we need 240V power supply.
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. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.
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 sound in the source room and receiver room (sharing a separating wall with the source room) 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 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.
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 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. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
Sound Testing Equipment to Expect
Our accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the building regulations. An airborne sound test measures levels of sound transmitted through the air through a separating element. We use pink or white noise generator and speakers on one side of the partition. A sound level meter is used on calculating sound in both units. 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. The outcome of the test is written in a report and sent to the customer. This report helps Building Control sign off your building.
A sound test is mandatory for these buildings:
The airborne and impact sound going through new and old buildings are evaluated by sound testing. This can impact adjoining walls and floors between the building.
Property with two or more units
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Converting a property into several units
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
Design not using 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. 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 requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.

Impact and airborne floor test
These are performed on floors and/or ceilings between units. An impact test measures the levels of noise transmitted directly through a separating construction. Impact and airborne testing is undertaken between party floors.
Our sound tests align to Part E of Building Regulations guideline, which thoroughly describes sound resistance level and performance from structures. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result for newly completed constructions. On the other hand, 64dB L’nTw or less impact sound and 43dB DnTw+Ctr or higher airborne sound insulation is expected from refurbished buildings.
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. We routinely give advice to developers and project managers from the beginning of the project, guaranteeing certainty when the time for a sound test is at hand.

Part E of building regulations resistance to the passage of sound (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.
Scotland Standard division for completed constructions
According to 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.” 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.
How to get a pass certificate for your sound 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. If you are unsure of how to build the separating floor and wall constructions and associated junctions across your development to satisfy the requirements of Document E 2003, we can offer design advice. 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. Take the following action to give your building the best opportunity to pass the sound insulation test: Inner and outer doors and windows have been installed and can be used Skirting boards are fitted Light switches, light fittingsand plug sockets are properly fitted 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.
Test and report certificates
We try to issue a certificate to give you the details of the test evaluation and report, by the next day. After the test, our site engineers will provide verbal results and advise you on how to solve potential problem or future areas of concern. 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.
What the results look like
You will get your sound insulation test certificate whether you pass or fail the sound tests. We can provide professional advice on designs that will surpass Document E standards if the building fails the test.
