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.
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. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
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 Sound Insulation Testing Does
To completely fulfil Building Regulations Part E requirements, the separating walls and floors of dwellings will be tested, unless approved Robust Details are 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
Even though sound insulation testing equipment produces lots of noise, sound testing requires quiet conditions and dwellings. Because of this, workers on the site would have to leave during the time of the test, to avoid errors in the test calculation. Sound insulation testing varies by size, complexity and conditions of site tested. A dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
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 complete report and sound insulation test certificate can be produced and issued within 24 working hours. 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). ADE goes on to define and group the type of structures that will undergo testing. They are houses, flats and rooms that are being used or are planned to be used as residences; such as student accommodation, care homes and hotel rooms. The extent of testing required for these three groups is shown below.
Why is Sound Insulation Testing Relevant?
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. The impact sound test result should not be more than 62dB L’nTw and the airborne sound insulation should not be less than 45dB DnTw+Ctr. 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. 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. Then there are developments where each neighbouring room / flat / unit has mixed uses. If the development has passed the sound insulation test, noise is reduced to a minimum.
Do I 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
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 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. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. 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.

When Should the Sound Tests be done?
We can undertake your sound tests when your building has almost been completed. By this time, you should have fixed internal and external doors and windows. We can conduct sound tests beforehand if required. For your sound tests to be conducted successfully we need the property to be quiet, with workers not near the rooms to be tested during the test time (a noisy environment makes the test difficult and sometimes unsuccessful). We also need access to all units unless the test program has been compiled earlier. Finally, we need 240V power supply.
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.
A big or multidirectional speaker, with a generator of pink or white noise is used to the biggest room. The sound in the source room and receiver room (sharing a separating wall with the source room) is measured with a sound level meter. 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. Airborne sound testing is done in a similar way. First, two speaker positions are used for each source room. Then, the level of sound in the receiver room is measured so that the difference in noise level between the two rooms can be calculated.
This basic level difference is then ‘corrected’ to allow for the reverberation time (the time is taken, in seconds, for a noise source to decay by 60dB) and the existing levels of background noise monitored whilst in the receiving room. Impact tests are carried out by means of a tapping machine placed on the floor to be measured. The noise level is then recorded in the room below. This is used in calculating and computing the results. These results are checked against Building Regulations ADE conditions for that kind of dwelling. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.
Kind of Testing Equipments Used
Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. An airborne sound test measures levels of sound transmitted through the air through a separating element. 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. 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.
A sound test is mandatory for these buildings:
For sound testing we usually undertake impact and airborne sound test on buildings. This affects the separating floors and walls between habitable rooms of buildings and developments.
Two or more new build dwellings or flats
This makes sure that the sound insulation for the building meets all the necessary requirements.
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.
Designs without Robust Details
Robust Detail Ltd set up the Robust Detail Scheme in 2004 to make sure architect and building designs construct partition walls and floors that comply with Approved Document E sound insulation standards. If the building design is slightly different from Robust Details, a sound test is essential so that Building Regulations criteria can be met. A building built as a permanent dwelling has different minimum standards from a building with rooms built for residential purpose, like a hotel or a hostel.

Impact and Airborne floor test
These are taken on separating floors/ceilings between residences. An impact test measures the levels of noise transmitted directly through a separating construction. Impact and airborne testing is undertaken between party floors.
Testing in line with Part E of Building Regulations
Document E of Building Regulations requires certain criteria for the sound performance of a dwelling. Our sound insulation tests are conducted in accordance to these criteria. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw for new structures. Converted properties get a slightly different requirement. Expected minimum airborne sound insulation test result is 43dB DnTw+Ctr while expected maximum impact sound test result is 64dB L’nTw.
With our professional and highly skilled expertise, we are willing to work with our clients to help them get a pass certificate in every situation. In new build properties an airborne test or an airborne and impact test may be required to ensure it meets the requirements of greater than 45dB DnTw+Ctr and less than 62dB L’nTw. We routinely give advice to developers and project managers from the beginning of the project, guaranteeing certainty when the time for a sound test is at hand.

Standard division for structures (Scotland)
Section 5.1 of the Scottish Building Standards 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 should be performed after construction, using the procedures given in annex 5.C. of the Scottish Standards. Standard 5.1 does not apply to: fully detached houses or roofs or walkways with access solely for maintenance, or solely for the use of the residents of the dwelling below.
How Do I Pass a Sound Insulation Test?
