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. It is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated in 2003.
At the completion of the test, a sound insulation certificate is issued. Without the certificate, Building Control will not release the building completion certificate to the contractors and developers of the project. 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. We take great pride in providing our certificates to you as soon as possible after the tests.
Even before you get the certificate, you will receive the results of the test. First, our skilled and competent sound insulation test will engineers give you a verbal result at the site. Then, a written report is sent to you within 24 hours of a working day.

How Sound Testing Works
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 testing measures the impact and airborne sound moving through new and old adjoining buildings. This tests include the boundary walls between buildings and in-between the spaces in a development.
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 way a sound test is administered depends on the size and type of building and the development’s condition. Most of the time the test will be conducted in 90 minutes, for a simple, regular sized construction.
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.
The entire report and individual sound test certificate will be sent to you the day after. 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 volume of testing carried out on each group is written below.
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. Results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. 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 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.
Sound insulation and speech privacy are critical for a variety of reasons. Inadequate sound insulation can be extremely distressing to those affected by it. 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. It can be useful in dwellings with neighbouring units/flats/rooms which have diverse purposes, by guaranteeing that an occupant in a room will hear as little noise as possible from the neighbouring room.
How Do I Know if I Need a Sound Test?
Are you converting your property into several units? Does your design not use Robust Details? Are you constructing a new building with more than two rooms? Are you building a nursing home or rooms that will used for residential purposes, like hotels and hostels? If so, your structure needs to undergo a sound test. Building Regulations Part E discusses sound testing in detail and has made it a requirement.
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 design details for separating elements, which have been tested before to comply with Document E standards. The Robust Details scheme means that testing is not necessary, but is strictly limited to the design given in the Robust Details approved list. Being able to adapt your design to suit your needs is more efficient and costs less in the long run. 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.

When can I carry out the sound insulation tests?
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.
The Process of a Sound Test
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. The boundary floors and walls get airborne tests. Floors get an additional impact test.
The airborne sound insulation test is carried out with a large speaker or dodecahedron speaker, using a white or pink noise generator to create the source sound, almost always in the largest room of the two rooms under testing. A sound level meter calculates the noise in the source room and receiver room. Noise in the background is also calculated. More noise in the background means a higher level of source sound will be created since it’s supposed to be 10dB higher than background noise on all calculated frequencies. 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.
The variations or differences in noise level are ‘corrected’ to take into consideration the already present background noise in the receiving room and the reverberation time – measure of time needed for a sound to decay or be absorbed in a closed room by 60dB. Impact tests are carried out by means of a tapping machine placed on the floor to be measured. 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. 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.
Sound Testing Equipment to Expect
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. 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. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. 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 necessary for these types of builds:
Sound testing measures the impact and airborne sound moving through new and old adjoining buildings. This could affect the separating walls between buildings or in-between the spaces in a development.
A new building with not less than two rooms
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Converting a property into several units
When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.
Using designs where Robust Details are not included
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. Once the design does not strictly abide by the design from Robust Detail approved list, the structure will have to undergo a sound test to ensure it conforms to Building Regulations. 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.
