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.
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 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. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
Our highly qualified site engineers can arrive on site when needed. They will provide verbal results after the test and a written report will be sent to you within 24 working hours.

What Sound Insulation 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 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. Most of the time the test will be conducted in 90 minutes, for a simple, regular sized construction.
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.
A full and thorough report with the certificate of the test will be given to you within 24 working hours. 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. Find below the testing stipulation for each kind of development.
Importance of Sound Insulation Testing
Document E of Building regulations, from 2003, made it compulsory for all new UK constructions to undertake a pre-completion sound test. 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. 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 having privacy while speaking are crucial for a number of reasons. When sound insulation is deficient, it can cause discomfort to occupants. It would mean noise moving from one flat to another in a block of flats. If, for example, an occupant works at night and happens to hear loud music from a neighbour upstairs on a weekend night, it would be very discomforting. 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.
Do You Need a Sound Test?
If you’re doing one of the following, then you need a sound test:
- Constructing a building that has two or more units
- Constructing a nursing home or rooms that will be lived in, e.g. hotel room or hostel
- Converting a single development to flats
- Using designs where Robust Details are not included
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. If you choose the latter, you must use Robust Details which are a approved design details for partitioning walls and floors. 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. 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. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.

Sound Insulation Test Time
The ideal period for a sound insulation test is after the fitting of windows and doors, and before the building is finished. If you want, AF Acoustics can conduct tests before then to find out if there are any problems on your property. 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 Done?
The method of taking the test is not complex and our sound test engineers can explain it thoroughly on site, if you wish. For partition walls, airborne tests are carried out. For floors there are two types, 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 sound in the source room and receiver room (sharing a separating wall with the source room) 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.
The sound difference is adjusted to make an allowance for reverberation time (time in which the sound decays by 60dB) and background noise in the receiver room. Impact tests are conducted by fixing a tapping machine on the floor. The room under it is then measured for the noise levels. 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.
What Sound Insulation Testing Equipment do we use?
You can expect UKAS calibrated equipment from us, as stipulated by Building Regulations. Our certified engineers conduct tests to meet the current guidelines. An airborne test is used to check how much sound is moving through the air between partitions. The equipment we use are a sound level meter, loudspeaker and white or pink noise generator. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. 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.
A sound test is mandatory for these buildings:
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 not less than two rooms
With the sound test, you can be certain that the property has a good acoustic performance.
Conversions of former single dwelling properties into flats
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Design that don’t have Robust Details factored in
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 building design is not in line with any Robust Details, it will require sound testing to ensure its compliance with the buildings regulations. The minimum requirements during testing will depend on a variety of factors such as if the development is intended to be a permanent dwelling, or classified as “rooms of residential purposes” (e.g. hotels, student accommodation, etc).

Airborne and impact tests for floors/ceilings
These are taken on separating floors/ceilings between residences. The calculation of the sound level transferred from one unit to another through a separating floor via impact is called an impact test. These floors in habitable rooms of flats undergo both impact and airborne tests.
Testing in line with Part E of Building Regulations
Our sound insulation testing in accordance with Building Regulations Approved Document E, which sets out details pertaining to the resistance to the passage of sound. 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.
Scotland Standard division for completed constructions
According to Section 5.1 of the Scottish Building Standards, “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 get a pass certificate for your 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. 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. We can study design reports, complete site visits and sound test the development to provide you with the level of assessment and consultation that your project requires from start to finish. The following conditions will provide you with an ample chance of passing the sound test: All windows and doors have been fitted and work Skirting boards are fixed are sealed Light fittings and switches and plug sockets are fitted and working. 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.
Test 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 do 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. If parts or all the building fails the test, repair work and a retest is recommended. We provide design advice to ensure your property does proper remedial and meets up with the necessary requirements.
