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. 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. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. We take great pride in providing our certificates to you as soon as possible after the tests.
Our fully trained sound insulation test engineers can be on site when you need them. Your AF Acoustics engineer will give you immediate verbal results from the sound test, and you can will have a written report by the following working day.

What Sound Testing Does
Walls and floors that separate dwellings in a building are expected to be sound tested, as mandated by Document E of Building Regulations. Only dwellings that have used Robust Details, which licensed before the installation, are exempted from the test. The airborne and impact sound going through new and old structures are evaluated by sound testing. This can impact adjoining walls and floors between the structures.
What is part of 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. A sound insulation test on a project is taken according to the scale and complexity of the construction and the conditions of the site. A dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
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.
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. Find below the testing stipulation for each kind of development.
Why is Sound Insulation Testing Relevant?
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. New builds must achieve impact sound test results of no more than 62dB L’nTw and airborne sound insulation of no less than 45dB DnTw+Ctr. 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. Testing for sound insulation is vital because sound influences how we live in the office, while relaxing or in the house. Restricting the sound that moves between floors and walls could result in a more relaxed and better surrounding.
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 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. Sound insulation helps improve the quality of a person’s life in diverse 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.
Do I 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
ADE thoroughly explains sound testing and makes it compulsory.
Either you follow the pre-completion sound testing process stipulated therein or you use Robust Details. This way, you have conformed to the requirements. 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. 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
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 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 Process of a Sound Test
Sound testing procedure is quite simple and our engineers are happy to explain this on site. The boundary floors and walls get airborne tests. Floors get an additional impact test.
A big or multidirectional speaker, with a generator of pink or white noise is used to the biggest room. A sound level meter is then used to take noise measurements within the source room and the receiver room. Noise in the background is also calculated. More noise in the background means a higher level of source sound will be created since it’s supposed to be 10dB higher than background noise on all calculated frequencies. Airborne sound testing is done in a similar way. First, two speaker positions are used for each source room. Then, the level of sound in the receiver room is measured so that the difference in noise level between the two rooms can be calculated.
Finally, the difference in noise level is modified to accommodate reverberation time and background noise that was already in the receiver room. Reverberation time is how long it takes sound to decay by 60dB. Impact tests are done by placing a standardised tapping machine on the floor. Noise level in the room below is measured at various different frequencies. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. 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.
Kind of Testing Equipments Used
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. 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. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. 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.
A structure with 2 or more units/flats
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Converting a property into several units
When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.
Designed in a way that does not adhere to Robust Details
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 building design is slightly different from Robust Details, a sound test is essential so that Building Regulations criteria can be met. The minimum requirements during testing will depend on a variety of factors such as if the development is intended to be a permanent dwelling, or classified as “rooms of residential purposes” (e.g. hotels, student accommodation, etc).

Building regulations for sound test
We provide sound testing and sound insulation testing on all types of buildings, for compliance with Part E Building Regulations in England and Wales and Section 5 of the Scottish Building Standards. Testing can also gain credits for Code for Sustainable Homes and EcoHomes environmental assessment schemes.
Part E of building regulations resistance to the passage of sound (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 developments (Scotland)
Section 5.1 of the Scottish Building Standards stipulates that “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.” Fully detached roofs or walkways that are not used for residential purposes do not have to take the sound tests of the Scottish Standards 5.1.
Passing a sound insulation 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. We offer design services that help you construct separating walls and floors with good sound performance that meet ADE demands. Our consultation process is led by your project requirements and may include assessment of design reports, test of the development and multiple site visits. The following conditions will provide you with an ample chance of passing the sound test: Inner and outer doors and windows have been installed and can be used Fit and seal skirting boards Light fittings and switches and plug sockets are fitted and working. 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
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.
The way the results look
A certificate will be issued to you whether the sound insulation treatment of the building meets the requirements of Document E of Building Regulations or not. If a partition wall or floor does not comply with Part E standards, repair work and another sound test will be needed. We can give robust advice on that to ensure you pass.
