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.
Not having a sound insulation certificate issued after a test, has resulted in additional costs and expenses for developers. Any development that has not taken a sound test will not be given a completion certificate by Building Control. 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. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
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 is a Sound Insulation Test?
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 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.
The Procedures Involved in a Sound Insulation Test
Workers on a site will vacate the premises while the sound test is being conducted. This will facilitate an enabling and quiet environment for the tests to be carried out. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. A dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
The sound testing engineers then proceed to give verbal results on the site and offer helpful advice on any problem areas noticed during the duration of the test.
A full report and individual sound test certificates can be generated and sent out the next day. The sound insulation testing methodology has been outlined by Document E of the Building Regulations. The document states that every 10 units in a sub-group or group should undergo one set of test, and defines a sub-group in Section 1. ADE also states the categories of developments that should be tested. There are three: rooms, flats and houses (including bungalows) that are lived in. Examples are student accommodation, hotel rooms and care homes. The extent of testing required for these three groups is shown below.
Why is Sound Insulation Testing Relevant?
After the 2003, Approved Document E mandates that all new structures in UK must take a sound insulation test before completion. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same building. 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.
There are so many more reasons why sound insulation and speech privacy are vital. An inefficient sound insulation treatment will lead to uneasiness for the inhabitants of the dwelling. 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 instance of the influence of sound insulation on our 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?
You need a sound insulation test if you’re:
- Constructing a nursing home or residential rooms like hostel or hotel rooms,
- Converting a building with a single dwelling into flats,
- Constructing a property with two or more units,
- Using designs without Robust Details to build
Building Regulations Part E discusses sound testing in detail and has made it a requirement.
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 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. With it, you don’t need a sound insulation test, but you must completely follow every aspect of the design from the Robust Detail Approved list. 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 does sound insulation testing cost?
Simply contact us and we will be able to provide a free, no obligation quotation as to the requirements and costs for your development. We have handled all kinds of sound insulation projects in UK and issue a report and certificate as quickly as possible. Our prices are affordable too and can beat others.
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. These are the things we need to conduct the test:
- 240V power supply
- A quiet environment
- Access to all the units of the structure unless places to test have been decided before then.
How is sound insulation testing carried out?
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. 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. The sound generated and received is measured with a sound level meter. Background noise is measured to make certain that the source noise is greater. This way the standard of the receiver room having a 10dB higher noise level at all calculated frequencies can be realised. 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. The noise level is then recorded in the room below. Calculations based on these measurements are undertaken and the results compared to the Building Regulations Part E requirements for the given type of the building. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.
Sound Test Equipment Used
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. 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. 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. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. Test findings are fed into a report that will be sent to the client. This report will always be acceptable to Building Control and will help you to get your development signed off.
A sound test is mandatory for these buildings:
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.
Converting a single development to flats
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Using designs where Robust Details are not included
The Robust Detail Scheme, set up in 2004 by Robust Details Ltd, architects create design details for walls and floors that were tested formerly for sound insulation and meet the sound performance parameters stated by Part E of Building Regulations. If the building design is not in line with any Robust Details, it will require sound testing to ensure its compliance with the buildings 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.

Resistance to the passage of sound: Approved Document E (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 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.
How to pass a sound test
All you have to do to pass your sound test is include adequate sound insulation in the design. That way, you save time and cost for repair work and re-test. 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. 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 door have been fixed and are functioning Skirting boards are fitted Light switches, light fittingsand plug sockets are properly fitted 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
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
Your test certificate will show if your development passed or failed the test and show if it adheres to the requirements of Part E of Building Regulations. 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.
