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. Part E of Building Regulations requires sound insulation in buildings and mandates that all newly completed constructions and rehabilitated developments go through sound testing.
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. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. We pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.
AF Acoustics’ competent and well-trained engineers, who will be available for testing, can even let you know the verbal results of your sound test. You will receive a written report in the space of a 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 testing conducts impact and airborne sound test on structures. The tests include the separating floors, walls and areas between buildings within developments.
What is part of a Sound Insulation Test
While producing lots of noise, sound test needs a quiet site to be conducted efficiently. Due to this fact, the workers in the site should not be present at the time of the test. The way a sound test is administered depends on the size and type of building and the development’s condition. A dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
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.
You will get a detailed written report and sound test certificate about a day after, if possible. 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. 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.
Why Should Your Dwelling Undergo Sound Testing
Before completing a building, all new constructions should be tested for sound insulation, as stipulated by Approved Document E since 2003. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. These result limits were put in to create and maintain a uniform standard for sound resistance in different parts of a dwelling and between adjacent buildings. Sound testing is essential due to the fact that sound impacts us wherever we are, whether it’s at home, leisure or the office. Reduced noise in the partitions and flooring of a structure leads to greater ease and a more efficient environment.
There are so many more reasons why sound insulation and speech privacy are vital. An inefficient sound insulation treatment will lead to uneasiness for the inhabitants of the dwelling. 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. Sound insulation helps improve the quality of a person’s life in diverse ways. 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.
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.
There are two ways in which to show compliance. You can either test to the regime set out in Approved Document E (ADE), or pay to use Robust Details. If you choose the latter, you must use Robust Details which are a approved design details for partitioning walls and floors. When you use it, you don’t have to take a sound insulation test. However, you must abide strictly by the design from the Robust Details approved list. Sound insulation testing is a more flexible approach. You can pick from a plethora of designs, as opposed to Robust Details. It also gives architects the opportunity to evaluate their design and give your structure a much better sound insulation which will increase sound performance.

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. To achieve the best results we would need the following during the test: quietness during the time of the test, 240V power supply and access to all the rooms unless a test plan has been agreed upon prior to the test time.
The Process of a Sound Test
The method of taking the test is not complex and our sound test engineers can explain it thoroughly on site, if you wish. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.
A pink or white noise generator and a large speaker is used for the test in the biggest room between the two undergoing 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 sound difference is adjusted to make an allowance for reverberation time (time in which the sound decays by 60dB) and background noise in the receiver room. Impact tests are conducted by fixing a tapping machine on the floor. Noise level in the room below is measured at various different frequencies. Calculations are done and the outcome is checked against ADE requirements for the type of building. This is a simple way of explaining how a sound test is conducted.
Type of Sound Insulation Test Machines We Will be using
The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. 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. 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. 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 essential for these dwelling types:
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.
Property with two or more units
With the sound test, you can be certain that the property has a good acoustic performance.
Converting a single development to 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
The Robust Detail Scheme, set up in 2004 by Robust Details Ltd, architects create design details for walls and floors that were tested formerly for sound insulation and meet the sound performance parameters stated by Part E of 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. 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 only carried out on separating floor/ceiling between dwellings. The calculation of the sound level transferred from one unit to another through a separating floor via impact is called an impact test. The adjoining floors/ceilings of rooms intended as residences usually have both impact and airborne sound tests.
Document E test
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. 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. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound insulation of no less than 43dB DnTw+Ctr.

Resistance to the passage of sound: Approved Document E (England and Wales)
We can send our authorised engineers to your development whenever the timing is ideal to undertake sound insulation testing that conforms to Building Regulations Document E consistence, as accepted by Building Control.
Scotland Standard division for completed constructions
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.” 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.
How Do I Pass 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. If you’re not certain of how to construct your party walls and floors, to meet Document E 2003 targets, simply contact us for an efficient design service. 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 door have been fixed and are functioning Skirting boards are fitted Light switches, plug sockets, and light fittings are adequately fixed. Our professional acoustic professionals work with contractors, architects, developers, and planner from the beginning of the design to make sure that all requirements are met.
Analysis and Report Certificates
We try to issue a certificate to give you the details of the test evaluation and report, by the next day. After the test, our site engineers will provide verbal results and advise you on how to solve potential problem or future areas of concern. 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 the results look like
A sound insulation certificate will be issued whether the Sound Testing results and report indicate compliance with Part E of the Building Regulations or not. If a partition wall or floor does not comply with Part E standards, repair work and another sound test will be needed. We can give robust advice on that to ensure you pass.
