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. 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.
As many contractors and developers have found to their detriment, without a sound insulation certificate, the Building Control Officer will not issue a completion certificate. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. We take great pride in providing our certificates to you as soon as possible after the tests.
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 is a Sound Insulation Test?
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. 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
The sound test itself produces very high levels of noise but also requires relatively quiet conditions on site. For these reasons, any workforce in the testing area will have to leave temporarily to ensure test accuracy. A sound insulation test on a project is taken according to the scale and complexity of the construction and the conditions of the site. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.
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 report and individual sound test certificates can be generated and sent out the next day. The sound testing guidelines are stipulated in Building Regulations ADE. It requires one set of test to be conducted on 10 units in a group or sub-group. You can find out what is meant by a sub-group in Section 1 of ADE. 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 Should Your Dwelling Undergo Sound Testing
After the 2003, Approved Document E mandates that all new structures in UK must take a sound insulation test before completion. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. This is to be certain that all new developments meet a uniform minimum criterion for resistance to sound from other parts of the development and adjoining developments. 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 having privacy while speaking are crucial for a number of reasons. When sound insulation is deficient, it can cause discomfort to occupants. 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 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.
Do I Need a Sound Insulation 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. Sound insulation is covered and made mandatory under Approved Document E of The Building Regulations.
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. 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.

Ideal Period for a Sound Insulation Test
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. 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
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 separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
A big or multidirectional speaker, with a generator of pink or white noise is used to the biggest room. A sound level meter calculates the noise in the source room and receiver room. Background sound is also calculated. Noise in the receiver room should be 10dB more than the background noise at all frequency measurements, so source noise is set to be greater than background noise. 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. A tapping machine is placed on the floor to execute an impact sound insulation test. The sound pressure level at the receiving room, which is below the source room, is measured. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. This is a simple way of explaining how a sound test is conducted.
What Sound Insulation Testing Equipment do we use?
Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. 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 pink or white noise generator and speakers on one side of the partition. A sound level meter is used on calculating sound in both units. 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. Test results, which are approved by Building Control and used to sign off the building, are recorded in a report and sent to the client.
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 structure with 2 or more units/flats
With the sound test, you can be certain that the property has a good acoustic performance.
Redevelopment of a building with a single dwelling into flats
When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.
Designed in a way that does not adhere to Robust Details
Robust Details Ltd began the Robust Details scheme in 2004. The scheme enables architects use design details for separating elements, which have been tested before to comply with Document E standards. If the building design does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building Regulations. The minimum requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.

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.” Fully detached roofs or walkways that are not used for residential purposes do not have to take the sound tests of the Scottish Standards 5.1.
Passing a sound insulation 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. Are you uncertain that the separating floor and walls you will build will adhere to Document E 2003 conditions? You can book our design services. 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 conditions will provide you with an ample chance of passing the sound test: All windows and door have been fixed and are functioning Fit and seal skirting boards 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.
