Sound insulation testing involves the use of specialist equipment to examine how much sound is reduced off by floors and walls, of a building. It checks if a dwelling’s sound proofing treatment meets the requirements set out in Approved Document E. It is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated in 2003.
Not doing so is a costly venture for developers and contractors as Building Control will not give a completion certificate for developments that have not undergone the test. Because we understand how the sound insulation certificate affects your building project, we ensure that you get it as quickly as possible after the test. In fact, we pride ourselves on issuing our sound insulation testing certificates as quickly as possible.
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?
In order to comply with Part E of the Building Regulations, developments will require the testing of separating walls and floors. The only exception is where Robust Details have been used. Sound insulation tests examine airborne and impact sound moving between separating walls and floors. The tests include party walls and floors between structures or between spaces within a new development.
The Procedures Involved in 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. A sound insulation test on a project is taken according to the scale and complexity of the construction and the conditions of the site. A structure that is simple and the conventional size will usually take 90 minutes to be tested.
Once it is completed, the engineers will give a verbal interim result on the site and basic helpful information on what was noticed during the test, e.g. possible sound issues and future places that could cause problems.
The entire report and individual sound test certificate will be sent to you the day after. The sound testing regime is set out in the Approved Document E of the Building Regulations. It states that one set of tests is required for every 10 units in a group or sub-group. Sub-groups are defined in Section 1 of Approved Document E (ADE). 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 Should Your Dwelling Undergo Sound Testing
Sound insulation testing is required because ADE of Building Regulations has made it compulsory for all new buildings to take a sound test prior to finishing construction. New builds must achieve impact sound test results of no more than 62dB L’nTw and airborne sound insulation of no less than 45dB DnTw+Ctr. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same 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.
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. 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?
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. It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. Robust Details are a set of specific design details for walls and floors that have been previously tested to show compliance and must be used if this route is selected. 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. 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.

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.
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. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.
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 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 done by placing a standardised tapping machine on the floor. The noise level is then recorded in the room below. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
Sound Testing Equipment to Expect
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. Equipment used for the test include a noise generator, speakers and sound level meter. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. The tests are administered in room with residential purposes. For example, kitchens/living spaces, lounges, bedrooms and living rooms. You will get the test results in a report within a working day. This report can be used to help sign off your building as it is accepted by Building Control.
These kinds of properties should undergo a sound insulation test:
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
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Converting a property into several units
The development that has been converted must conform to Building Regulations sound requirements.
Designs without Robust Details
The Robust Details scheme was set up in 2004 by Robust Details Ltd as a way to help architects and builders design and construct separating elements with the confidence that the separating wall and/or floor will be capable of achieving the sound performance parameters in Approved Document E, and comply with the Building Regulations. If the building design is slightly different from Robust Details, a sound test is essential so that Building Regulations criteria can be met. Minimum criterion differs based on the type and purpose of the development. A development with rooms intended as residences, like a hostel or hotel, won’t have the same criteria as a structure for permanent dwelling.

Building Standards Division (Scotland)
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.” Tests should be taken at the completion of the building, using procedures given in annex 5.C. of the Scottish Standards. These standards don’t apply to detached structures that have access only for maintenance or are to used only by the occupants who live below.
How Do I Pass a Sound Insulation 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. 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 will give you a better chance of passing the sound test: Windows and internal and external doors are fitted and operable Skirting boards are fixed Fix all light switches, light fittings and plug sockets. We work with several professionals in construction from the beginning of the design stage to the completion of the development to make certain it conforms to Document E 2003 of Building Regulations.
