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. Because we understand how the sound insulation certificate affects your building project, we ensure that you get it as quickly as possible after the test. When the tests are completed, we work quickly to issue your certificates; we take great pride in our efficiency.
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
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 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 Insulation Testing
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 process of a sound test is determined by the size and complexity of the site being tested. A structure that is simple and the conventional size will usually take 90 minutes to be tested.
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.
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 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. Find below the testing stipulation for each kind of development.
Why is Sound Insulation Testing Required? Why is it Important?
Before completing a building, all new constructions should be tested for sound insulation, as stipulated by Approved Document E since 2003. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same building. 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 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. 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.
Does Your Development 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
It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
There are 2 ways you can comply. Test for sound insulation using the method of Approved Document E or use Robust Details in your development. Robust Details are design details for walls that were tested formerly and meet the sound performance parameters stated by Part E of Building Regulations. When you use it, you don’t have to take a sound insulation test. However, you must abide strictly by the design from the Robust Details approved list. 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. On-site pre-completion sound insulation testing gives architects more insight and ability to make their design lead to constructions that have a higher sound 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 Process of a Sound Test
Our sound test engineers can answer your questions and make the sound test process easy to understand on site, during the time of the test. 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. 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.
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 conducted by fixing a tapping machine on the floor. The noise level is then recorded in the room below. Once the calculations are completed and the result is achieved, it is compared with Building Regulations Part E standards. 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 test calculates the amount of sound moving through a separating element. Equipment used for the test include a noise generator, speakers and sound level meter. 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. 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 necessary for these types of builds:
Sound testing measures the impact and airborne sound moving through new and old adjoining buildings. This could affect the separating walls between buildings or in-between the spaces in a development.
Two or more new build dwellings or flats
This is to ensure that the sound proofing of the building is up to standard for residential purposes.
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.
Design not using 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.

Airborne and impact tests for floors/ceilings
These are only carried out on separating floor/ceiling between dwellings. Impact testing evaluates how much the sound flowing from one partition to another through party floors via impact is. Airborne and impact tests are conducted on the floor partitions between liveable rooms.
Testing in line with Part E of Building Regulations
Our sound tests align to Part E of Building Regulations guideline, which thoroughly describes sound resistance level and performance from structures. For new buildings, results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. Converted structures expected impact sound results increases by 2dB L’nTw while the airborne sound results reduces by 2dB DnTw+Ctr.

We have fully accredited engineers who can visit your property to issue appropriate certification that complies with the building control.
Standard division for structures (Scotland)
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 pass a 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. We offer design services that help you construct separating walls and floors with good sound performance that meet ADE demands. Whether you want some initial tests on your project, or comprehensive reports at the end, we can help you at the level that you need. The following conditions will provide you with an ample chance of passing the sound test: Install and make sure that all external and internal doors and windows are operational Skirting boards are fixed Fix all light switches, light fittings and plug sockets. 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.
Certificates for test evaluation and report
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 do the results look like?
A sound insulation certificate will be sent to you whether the property has a good sound performance in accordance with ADE or not. In the event of a wall or floor not achieving the Part E requirements, it may be necessary to carry out remedial works before having another sound test carried out. We can provide you with remedial design advice to help you achieve the Building Regulations requirements.
