Sound insulation testing involves the use of specialist equipment to examine how much sound is reduced off by floors and walls, of a building. It checks if a dwelling’s sound proofing treatment meets the requirements set out in Approved Document E. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo sound testing.
Not doing so is a costly venture for developers and contractors as Building Control will not give a completion certificate for developments that have not undergone the test. 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. We pride ourselves on the facts that our sound insulation certificates are issued with speed and 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 Insulation Testing Does
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.
What is involved in Sound testing?
A sound insulation test creates a high amount of noise but needs a site with low noise levels to be taken effectively. As a result of this, workers in a testing area might have to leave the development temporarily, so that the test can be free from errors. 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 test, the sound insulation test engineers will let you know the outcome of the test and supply simple feedback of important things noted during the test; e.g. problems that might occur in the future.
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 is Sound Insulation Testing Relevant?
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. 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.
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. In a structure with flats for mixed purposes, a sound insulation test will make sure that there is maximum sound resistance from party walls and floors and less noise.
How to Know if You Need Sound Insulation Testing
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.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. 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. 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. Sound testing provides more flexibility by allowing different designs and is often therefore more cost effective in many ways compared to the Robust Details Scheme. When on-site pre–completion building sound tests are taken, architects have more scope with their design and can increase the sound insulation performance of the construction.

Ideal Period for a Sound Insulation Test
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. 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
The method of taking the test is not complex and our sound test engineers can explain it thoroughly on site, if you wish. 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 calculates the noise in the source room and receiver room. 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 tests, two speakers positions are used in the source room and the level of noise entering into the receiving partition room is measured. That way the difference in sound level is calculated.
This difference is modified to include background noise in the receiver room and reverberation time – time whereby a sound fades away in a closed space by 60dB. Impact tests are done by placing a standardised tapping machine on the floor. The sound level in the room below it is recorded. Calculations are done and the outcome is checked against ADE requirements for the type of building. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
What Sound Insulation Testing Equipment do we use?
Our accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the 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. 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 can only be completed on ‘habitable’ rooms. Habitable rooms can be bedrooms, lounges, living rooms and open plan kitchen/ living spaces. 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.
Sound insulation testing is essential for these dwelling types:
Sound Insulation Testing checks for both airborne and impact noise travelling through new or existing buildings. This may affect party walls and floors between new and existing buildings, or between spaces within a new development.
A new building with 2 or more dwellings
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Redevelopment of a building with a single dwelling into flats
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
Design not using Robust Details
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 design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. The minimum criterion is based on various factors such as the purpose of the development and if it is a permanent dwelling or rooms to be used as residences like students’ accommodations and hotels.

Impact and airborne tests for floors
These are only carried out on separating floor/ceiling between dwellings. An impact test examines the level of noise moving from one dwelling to another through impact on adjoining floors/ceilings. These floors in habitable rooms of flats undergo both impact and airborne tests.
Our sound tests align to Part E of Building Regulations guideline, which thoroughly describes sound resistance level and performance from structures. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result for newly completed constructions. On the other hand, 64dB L’nTw or less impact sound and 43dB DnTw+Ctr or higher airborne sound insulation is expected from refurbished buildings.
We want to give our customers the most highest chance to acquire a pass and via our offer skilled services. In new properties, an airborne and impact test will help you guarantee the building meets the requirements of greater than 45dB DnTw+Ctr and less than 62dB L’nTw.

Scotland Standard division for completed constructions
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.” The following are exempt from the testing techniques given in annex 5.C. of the Scottish Standard and Standard 5.1 – completely segregated rooftops, houses or walkways whose access is only used for upkeep or for the utilization of the inhabitants of the dwelling beneath.
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. 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: Install and make sure that all external and internal doors and windows are operational Skirting boards are fitted and sealed 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.
Investigation and report certificates
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 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. 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.
