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. It is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated in 2003.
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. 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. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
Even before you get the certificate, you will receive the results of the test. First, our skilled and competent sound insulation test will engineers give you a verbal result at the site. Then, a written report is sent to you within 24 hours of a working day.

What is a Sound Insulation Test?
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 Insulation Testing tests for both the airborne sound and the impact sound which travels through new or existing buildings . The tests cover party walls and floors between new and existing buildings, or between spaces within a new development entirely.
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. The way a sound test is administered depends on the size and type of building and the development’s condition. A structure that is simple and the conventional size will usually take 90 minutes to be tested.
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. 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 volume of testing carried out on each group is written below.
Why Sound Testing is Required
Before completing a building, all new constructions should be tested for sound insulation, as stipulated by Approved Document E since 2003. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. These result limits were put in to create and maintain a uniform standard for sound resistance in different parts of a dwelling and between adjacent buildings. Sound testing is essential due to the fact that sound impacts us wherever we are, whether it’s at home, leisure or the office. Reduced noise in the partitions and flooring of a structure leads to greater ease and a more efficient 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 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.
How Do I Know if I 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.
It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
All you have to do is follow the guidelines listed in the document or pay to use Robust Details and you will have fulfilled the requirements. Robust Details are design details for separating elements, which have been tested before to comply with Document E standards. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. With sound testing, however, you’re free to pick from any design, including more cost effective and appropriate ones. This makes it a more efficient process than Robust Details. 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. During the test, you should provide the following:
- Access to all rooms. The only exception is if a schedule was created before the test time.
- 240V power supply
- A noiseless site
How is sound insulation testing carried out?
Sound testing procedure is quite simple and our engineers are happy to explain this on site. We carry out airborne and impact tests on separating floors, and airborne tests on separating walls.
A pink or white noise generator and a large speaker is used for the test in the biggest room between the two undergoing testing. A sound level meter is then used to take noise measurements within the source room and the receiver room. 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. When conducting airborne sound insulation tests, two speakers are placed in each source room. The noise level in the receiving room is measured to get the sound difference between the source and receiving room.
This basic level difference is then ‘corrected’ to allow for the reverberation time (the time is taken, in seconds, for a noise source to decay by 60dB) and the existing levels of background noise monitored whilst in the receiving room. 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. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.
Sound Test Equipment Used
Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. 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. We use a tapping machine, which drops metal hammers onto the floor to create impact noise. We then measure the amount of sound that passes through the partition with a sound level meter in the room under the tapping machine. Testing is done on rooms that can be lived in. E.g. lounges, kitchens, bedrooms and living rooms. 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.
Sound insulation testing is essential for these dwelling types:
For sound testing we usually undertake impact and airborne sound test on buildings. This affects the separating floors and walls between habitable rooms of buildings and developments.
A new building with 2 or more dwellings
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
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.
Designs without Robust Details
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. If the building design is slightly different from Robust Details, a sound test is essential so that Building Regulations criteria can be met. 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.

Building regulations for sound test
Our sound insulation tests are conducted in accordance with Part E Building Regulations in England and Wales and Section 5 of the Scottish Building requirements. You can also get credits for Code for Sustainable Homes and EcoHomes environmental assessment projects.
Building regulations document E resistance to the passage of sound (England and Wales)
We can send our authorised engineers to your development whenever the timing is ideal to undertake sound insulation testing that conforms to Building Regulations Document E consistence, as accepted by Building Control.
Standard division for developments (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.” 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.
How to get a pass certificate for your sound test
The most effective way to ensure you pass your sound test is to plan the project with sound insulation in mind. This does not need to be costly, and can save considerable time and expense at the end of the project, not to mention avoiding escalating remedial and re-test costs. 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. The degree of guidance you require can vary, from site visits and comprehensive design reports, to simpler initial testing to know the starting point for construction. 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 Skirting boards are fixed are sealed Light switches, light fittingsand plug sockets are properly fitted Our accomplished acoustic consultants work with developers, planners, contractors, and architects of all sizes from the early stages of the building plan to help limit any potential sound insulation performance problems to the completion of the construction, guaranteeing that all properties meet the criteria of Building Regulations Document E 2003.
Test report certificates
After the sound insulation test, the sound testing engineer will provide provisional results whilst on-site, as well as providing basic feedback about what has been noted during the test, e.g. potential problems or any future areas of concern. A full report and individual sound test certificates can be generated and sent out usually 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 the results look like
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.
