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.
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. 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.
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.

What Sound Testing Does
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. 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 Sound Insulation Testing
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. The way a sound test is administered depends on the size and type of building and the development’s condition. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.
The sound testing engineers then proceed to give verbal results on the site and offer helpful advice on any problem areas noticed during the duration of the test.
You will get a detailed written report and sound test certificate about a day after, if possible. 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. The extent of testing required for these three groups is shown below.
Importance of Sound Insulation Testing
Before completing a building, all new constructions should be tested for sound insulation, as stipulated by Approved Document E since 2003. 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. This Approved Document, as part of UK Building Regulations helps to ensure that new buildings are constructed to minimum standards that provide reasonable resistance to sound from other parts of the same building and from adjacent buildings. 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. 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 example of how sound insulation can affect the quality of life of people in different ways. 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
Document E of the Building Regulations explains sound insulation testing and makes it a necessity.
There are 2 ways you can comply. Test for sound insulation using the method of Approved Document E or use Robust Details in your development. 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. 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
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. 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?
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. 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 is then used to take noise measurements within the source room and the 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. When conducting airborne sound insulation tests, two speakers are placed in each source room. The noise level in the receiving room is measured to get the sound difference between the source and receiving room.
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 conducted by fixing a tapping machine on the floor. The room under it is then measured for the noise levels. This is used in calculating and computing the results. These results are checked against Building Regulations ADE conditions for that kind of dwelling. 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 accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the building regulations. 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 a loudspeaker and noise generator that produces white or pink noise on one side of the partition, and measure with a sound level meter on both sides to calculate the sound insulation performance of the partition. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. 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.
A sound test is mandatory for these buildings:
The airborne and impact sound going through new and old buildings are evaluated by sound testing. This can impact adjoining walls and floors between the building.
A new building with not less than two rooms
This makes sure that the sound insulation for the building meets all the necessary requirements.
Conversions of former single dwelling properties into flats
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
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 not in line with any Robust Details, it will require sound testing to ensure its compliance with the buildings 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.

Standard division for developments (Scotland)
In the words of Section 5.1 of the Scottish Building Standards, “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.” The following are exempt from the testing techniques given in annex 5.C. of the Scottish Standard and Standard 5.1 – completely segregated rooftops, houses or walkways whose access is only used for upkeep or for the utilization of the inhabitants of the dwelling beneath.
How to get a pass certificate for your sound test
The most effective way to ensure you pass your sound test is to plan the project with sound insulation in mind. This does not need to be costly, and can save considerable time and expense at the end of the project, not to mention avoiding escalating remedial and re-test costs. We offer design services that help you construct separating walls and floors with good sound performance that meet ADE demands. 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 criteria should be followed to provide you with the best chance of passing your sound test: All windows and doors have been fitted and work Skirting boards are fitted and sealed Light switches, plug sockets, and light fittings are adequately fixed. 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.
Test and report certificates
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. A full report and individual sound test certificates can be generated and sent out usually the next working day. 6. Even before you get the certificate, you get the verbal results of the test. First, our completely skilled and competent sound insulation test engineers give you a verbal result at the site. They also offer advice on potential problems. Then the test report certificate is sent to you within 24 working hours, when feasible.
What do the results look like?
Your test certificate will show if your development passed or failed the test and show if it adheres to the requirements of Part E of Building Regulations. In the event that some part of the building does not meet up with the conditions of Document E, remedial work and a retest is required. We give remedial design advice to help you achieve Building Regulations standards.
