Sound insulation testing is used to measure the resistance of sound provided by an element of a building (such as a floor or wall) between dwellings. It essentially measures the effectiveness of the sound proofing treatment installed as part of a build or property development. Part E of Building Regulations requires sound insulation in buildings and mandates that all newly completed constructions and rehabilitated developments go through sound testing.
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 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. When the tests are completed, we work quickly to issue your certificates; we take great pride in our 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 Insulation 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. The airborne and impact sound going through new and old structures are evaluated by sound testing. This can impact adjoining walls and floors between the structures.
What is part of 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. The way a sound test is administered depends on the size and type of building and the development’s condition. A dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
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.
A full and thorough report with the certificate of the test will be given to you within 24 working hours. The way a sound test is conducted is determined by ADE of Building Regulations. It mandates that in all developments, every 10 units in a group or sub-group will undertake one set of tests. It explicitly states what a sub-group is in Section 1. Buildings to be tested are categorised into three kinds: houses, flats and rooms like care homes, student accommodation 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 impact sound test result should not be more than 62dB L’nTw and the airborne sound insulation should not be less than 45dB DnTw+Ctr. 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.
Insufficient sound insulation causes distress and comfort while an effective sound insulation system brings about speech privacy. This is one of the several reasons why sound insulation is a key element in building. For instance, in an apartment building, the neighbour upstairs might invite friends over during the weekend and put on loud music. The inhabitant downstairs might spend night hours as work time. If the sound insulation is inefficient, this could lead to lots of problems. 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 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.
ADE thoroughly explains sound testing and makes it compulsory.
Either you follow the pre-completion sound testing process stipulated therein or you use Robust Details. This way, you have conformed to 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. 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. Conducting on-site pre-completion sound testing also enables the architects more scope with their design and can lead to improved sound insulation performance.

Sound Insulation Test Time
The best time for a sound insulation test is just before the construction of the property is finished and after all windows and doors are fixed. However, in the case of a problem we can take the test before then. 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 insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. The noise from the source room and received by the receiver room, and background noise is measured with a sound level meter. The meter is also used to measure the background sound, to ensure that it’s 10dB lower than the source sound, as is the standard. More background sound leads to creating a higher source sound. 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.
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 conducted by fixing a 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. Of course, this is a simple way of describing the procedure followed when a sound test is carried out, but it enables you to understand it better.
Type of Sound Insulation Test Machines We Will be using
The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. The calculation of the level of noise transmitted through the air between two adjoining units is known as an airborne sound insulation test. 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 test, a tapping machine that makes impact sound by dropping metal hammers is used. A sound level meter is used to measure in the receiving room below the room the tapping machine is in. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. The outcome of the test is written in a report and sent to the customer. This report helps Building Control sign off your building.
Sound Insulation Testing is necessary for these types of builds:
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 makes sure that the sound insulation for the building meets all the necessary requirements.
Converting a property into several units
The development that has been converted must conform to Building Regulations sound requirements.
Design not using Robust Details
Architects are able to use pre-tested and approved Robust Details design for partitioning walls and floors. The Robust Details scheme was formed in 2004 by Robust Details Ltd. If the design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. A building built as a permanent dwelling has different minimum standards from a building with rooms built for residential purpose, like a hotel or a hostel.

Sound resistance and performance: Document E of Building Regulations (England and Wales)
Our expert engineers can issue certificates for the sound insulation testing. They can visit the site and conduct the test that will lead to getting a certificate which is in line with Building Regulations and Building Control requirements.
Building Standards Division (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.” Tests, which are conducted after building utilizing the methodology given in annex 5.C. of the Scottish Standard 5.1 does not apply to: completely disconnected houses, rooftops and walkways with access exclusively for the use of the occupants of the home underneath.
How to pass a sound test
The most efficient way to make sure you pass sound insulation test is to have a plan that puts sound insulation into consideration from the begining. You don’t have to spend too much for this and it will save you money in the long run, ensuring you don’t pay remedial or re-test expenses. We offer design services to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. 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 criteria should be followed to provide you with the best chance of passing your sound test: All windows and doors have been fitted and work Skirting boards are fixed Plug sockets, light switches and fittings are in place and working. 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.
Analysis and Report Certificates
After the test, AF Acoustics’ competent and well trained engineers can let you know the verbal results of your sound test and provide feedback on issues noticed during the test. We endeavour to send an investigation and report certificate 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 do the results look like?
You will get your sound insulation test certificate whether you pass or fail the sound tests. 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.
