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.
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. We pride ourselves on the facts that our sound insulation certificates are issued with speed and 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
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 Sound testing?
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. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. A structure that is simple and the conventional size will usually take 90 minutes to be tested.
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.
A full report and individual sound test certificates can be generated and sent out the next day. 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 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. The extent of testing required for these three groups is shown below.
Importance of Sound Insulation Testing
Sound insulation testing is required because ADE of Building Regulations has made it compulsory for all new buildings to take a sound test prior to finishing construction. Results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. This is to be certain that all new developments meet a uniform minimum criterion for resistance to sound from other parts of the development and adjoining developments. 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 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 just one example of how sound insulation can affect the quality of life of people in different ways. Then there are developments where each neighbouring room / flat / unit has mixed uses. If the development has passed the sound insulation test, noise is reduced to a minimum.
Does Your Development Need a Sound Insulation Test?
If you’re doing one of the following, then you need a sound test:
- Constructing a building that has two or more units
- Constructing a nursing home or rooms that will be lived in, e.g. hotel room or hostel
- Converting a single development to flats
- Using designs where Robust Details are not included
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 design details for walls that were tested formerly and meet the sound performance parameters stated by Part E of Building Regulations. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. 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.

Ideal Period for a Sound Insulation Test
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. 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.
The Procedures of a Sound Insulation Test
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. For partition walls, airborne tests are carried out. For floors there are two types, 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 sound is also calculated. Noise in the receiver room should be 10dB more than the background noise at all frequency measurements, so source noise is set to be greater than background noise. 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 carried out by means of a tapping machine placed on the floor to be measured. Noise level in the room below is measured at various different frequencies. Calculations are done and the outcome is checked against ADE requirements for the type of building. Of course, this is a simple way of describing the procedure followed when a sound test is carried out, but it enables you to understand it better.
Type of Sound Insulation Test Machines We Will be using
The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. An airborne test calculates the amount of sound moving through a separating element. We use a loudspeaker and noise generator that produces white or pink noise on one side of the partition, and measure with a sound level meter on both sides to calculate the sound insulation performance of the partition. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. 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.
It’s important to undertake a sound test if you have this kind of building:
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.
A new building with not less than two rooms
This is to ensure that the sound proofing of the building is up to standard for residential purposes.
Conversions of former single dwelling properties into flats
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
Using designs where Robust Details are not included
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 requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.

Sound resistance and performance: Document E of Building Regulations (England and Wales)
We can have fully accredited engineers sent to your property at your convenience to provide certification for Building Regulations Part E compliance, recognised by Building Control.
Standard division for structures (Scotland)
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, which are conducted after building utilizing the methodology given in annex 5.C. of the Scottish Standard 5.1 does not apply to: completely disconnected houses, rooftops and walkways with access exclusively for the use of the occupants of the home underneath.
How to make sure you pass your sound test
Make sure you pass your sound test by having efficient sound insulation included in the building design. It saves time and money and helps you avoid repair work and re-test expenses. Are you uncertain that the separating floor and walls you will build will adhere to Document E 2003 conditions? You can book our design services. Our consultation may include several site visits and thorough design reports, or more basic initial tests on your structure. The following conditions will provide you with an ample chance of passing the sound test: All windows and doors have been fitted and work Skirting boards are fixed are sealed Plug sockets, light switches and fittings are in place and working. Our professional acoustic professionals work with contractors, architects, developers, and planner from the beginning of the design to make sure that all requirements are met.
Test report certificates
After the test, AF Acoustics’ competent and well trained engineers can let you know the verbal results of your sound test and provide feedback on issues noticed during the test. We endeavour to send an investigation and report certificate the next working day. 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 do the results look like?
A sound insulation certificate will be issued whether the Sound Testing results and report indicate compliance with Part E of the Building Regulations or not. We can provide professional advice on designs that will surpass Document E standards if the building fails the test.
