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. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo 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. We know how important a sound insulation certificate is to you. That is why we work hard to make certain that you get the certificate quickly. We pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.
AF Acoustics’ competent and well-trained engineers, who will be available for testing, can even let you know the verbal results of your sound test. You will receive a written report in the space of a working day.

What Sound Testing Does
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 tests examine airborne and impact sound moving between separating walls and floors. The tests include party walls and floors between structures or between spaces within a new development.
The Procedures Involved in a Sound Insulation 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. A sound insulation test on a project is taken according to the scale and complexity of the construction and the conditions of the site. If the site is simple and of regular size, it typically takes about 90 minutes to complete the sound test.
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.
The entire report and individual sound test certificate will be sent to you the day after. 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. How much testing that is required for each category can be found below.
Why Should Your Dwelling Undergo Sound Testing
Document E of Building regulations, from 2003, made it compulsory for all new UK constructions to undertake a pre-completion sound test. 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. 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 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 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 one way sound insulation can affect how a person lives. Sound insulation is also effective in buildings that have flats with mixed uses. If the building passed the sound test, you can be sure that noise reduction will be effective.
Do You Need a Sound 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. Sound insulation is covered and made mandatory under Approved Document E of The Building Regulations.
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 separating elements, which have been tested before to comply with Document E standards. Using Robust Details, without taking a test, limits you to the design you’ve picked. Sound insulation testing is a more flexible approach. You can pick from a plethora of designs, as opposed to Robust Details. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.
How Much Will I Pay for a Sound Insulation Test?
We can send quotation that’s completely free of charge and is based on the kind of development you have. We have tested all types and sizes of construction in the UK and issue a report and sound test certificate within 24 working hours. We offer one of the best prices. If you get a better price from another company, let us know and we will try to beat it.
When Should the Sound Tests be done?
We can undertake your sound tests when your building has almost been completed. By this time, you should have fixed internal and external doors and windows. We can conduct sound tests beforehand if required. 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. 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. 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.
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. This is used in calculating and computing the results. These results are checked against Building Regulations ADE conditions for that kind of dwelling. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.
Sound Testing Equipment to Expect
Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. An airborne sound test measures levels of sound transmitted through the air 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. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. Test results, which are approved by Building Control and used to sign off the building, are recorded in a report and sent to the client.
A sound test is mandatory for these buildings:
Sound insulation tests examine airborne and impact sound moving through buildings. It is usually undertaken between party walls and floors between buildings or between spaces within a new development.
A structure with 2 or more units/flats
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Conversions of former single dwelling properties into flats
When the development is completed, ADE of Building Regulations should be checked, and sound insulation tested accordingly.
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. 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. 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 ceilings/floor tests
These are taken on separating floors/ceilings between residences. Impact testing evaluates how much the sound flowing from one partition to another through party floors via impact is. The adjoining floors/ceilings of rooms intended as residences usually have both impact and airborne sound tests.
Testing in line with Part E of Building Regulations
Document E of Building Regulations requires certain criteria for the sound performance of a dwelling. Our sound insulation tests are conducted in accordance to these criteria. 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. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound insulation of no less than 43dB DnTw+Ctr.
With our professional and highly skilled expertise, we are willing to work with our clients to help them get a pass certificate in every situation. 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 regularly provide consultations for project managers and developers from the very start of developments, ensuring peace of mind when it comes time to having a sound test.

Resistance to the passage of sound: Approved Document E (England and Wales)
We have fully accredited engineers who can visit your property to issue appropriate certification that complies with the 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.” 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.
Passing a sound insulation test
The best method to guarantee you pass your sound test is to design the building with a view to good sound insulation performance. This shouldn’t be exorbitant, and can save time and cost at the end, without your having to correct sound problem or pay for a re-test. We offer design services to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. 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: Windows and internal and external doors are fitted and operable Skirting boards are fitted and sealed Fix all light switches, light fittings and plug sockets. Our expert acoustic consultants work with planners, developers, architects and contractors from the beginning of the design stage till when the property is finished to ensure it meets the conditions of Document E 2003.
Certificates for test evaluation and report
To get details of the results of a completed sound insulation test, we will provide you with an analysis and report certificate. 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. In the event that some part of the building does not meet up with the conditions of Document E, remedial work and a retest is required. We give remedial design advice to help you achieve Building Regulations standards.
