The measurement of the sound reduced by partitions in a development, such as a wall or floor, is known as sound insulation testing or sound testing. It assesses how good the soundproofing materials fixed to the property development are. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo 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. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. We pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.
Our highly capable sound test engineers will be available on site when you need them. They will give you a verbal result of the test, once taken and a written report will be issued to you by the following working day.

What is a Sound Insulation Test?
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 a Sound Test
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 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.
You will get a detailed written report and sound test certificate about a day after, if possible. 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 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.
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. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. 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 affects our life no matter where we are, at home, work or while relaxing. Places with lowered noise are more comfortable and enabling. Sound testing ensures that noise reduction in a building is effective.
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 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.
Does Your Development Need a Sound Insulation 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.
All you have to do is follow the guidelines listed in the document or pay to use Robust Details and you will have fulfilled the requirements. Robust details are separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. 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 testing provides more flexibility by allowing different designs and is often therefore more cost effective in many ways compared to the Robust Details Scheme. It also gives architects the opportunity to evaluate their design and give your structure a much better sound insulation which will increase sound performance.

Ideal Period for a Sound Insulation Test
A sound test is usually conducted just before the construction is completed, and when all the doors and windows have been fixed. However, we can test your building earlier to check for problems. 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.
The Procedures of a Sound Insulation Test
Our sound test engineers can answer your questions and make the sound test process easy to understand on site, during the time of the test. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
The test uses a dodecahedron speaker and pink or white noise generator for source sound. The sound source is placed in the largest room of the two. 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 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.
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 sound pressure level at the receiving room, which is below the source room, is measured. Calculations are done and the outcome is checked against ADE requirements for the type of building. This is a simple way of explaining how a sound test is conducted.
Sound Test Equipment Used
Our accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the building regulations. An airborne sound test measures levels of sound transmitted through the air 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. A sound level meter and a tapping machine which drops metal hammers is used for impact testing. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. 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 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 new building with not less than two rooms
With the sound test, you can be certain that the property has a good acoustic performance.
A single dwelling that was turned into a development with several flats or units
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
Design that don’t have Robust Details factored in
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. 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).

Our certified engineers can come to your building whenever it might suit you to undertake sound insulation testing to Part E of Building Regulations adherence, recognised by Building Control.
Building Standards Division (Scotland)
Section 5.1 of the Scottish Building Standards explicitly describes expected energy performance of dwellings. It 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 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.
