Sound testing calculates the extent to which sound is blocked by the partition (walls, floors etc) of a building between dwellings. It evaluates the efficiency of the soundproofing materials that make up the structure. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo sound testing.

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. 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. We take great pride in providing our certificates to you as soon as possible after the tests.

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 Test?

Walls and floors that separate dwellings in a building are expected to be sound tested, as mandated by Document E of Building Regulations. Only dwellings that have used Robust Details, which licensed before the installation, are exempted from the test. Sound testing conducts impact and airborne sound test on structures. The tests include the separating floors, walls and areas between buildings within developments.

The Procedures Involved in 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. A structure that is simple and the conventional size will usually take 90 minutes to be tested.

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 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. Find below the testing stipulation for each kind of development.

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. Results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. 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 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.

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, an inhabitant in an apartment building sleeps during the day and works at night all the days of the week. If the neighbour in the upstairs flat has friends over and plays loud music, without a good sound insulation system, the working occupant will be uncomfortable and uneasy. 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. Document E of the Building Regulations explains sound insulation testing and makes it a necessity.

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. 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. 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. 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 can I carry out the sound insulation tests?

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 Done?

The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.

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. 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. For airborne sound tests, two individual speaker positions are used for each source room. Measurements are then made to determine the levels in the receiving room of the tested partition in question. This gives a basic level difference between source and receiver rooms.

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. 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. 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.

What Sound Insulation Testing Equipment do we use?

The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. An airborne test is used to check how much sound is moving through the air between partitions. 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. Testing is done on rooms that can be lived in. E.g. lounges, kitchens, 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 necessary for these types of builds:

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.

A new building with 2 or more dwellings

This is to ensure that the sound proofing of the building is up to standard for residential purposes.

Converting a single development to flats

The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.

Design that don’t have Robust Details factored in

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. 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.

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.

Standard division for developments (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 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 to make sure you pass your sound test

All you have to do to pass your sound test is include adequate sound insulation in the design. That way, you save time and cost for repair work and re-test. 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. Our consultation may include several site visits and thorough design reports, or more basic initial tests on your structure. The following conditions will provide you with an ample chance of passing the sound test: Install and make sure that all external and internal doors and windows are operational Skirting boards are fitted and sealed Light switches, plug sockets, and light fittings are adequately fixed. 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.

Investigation and report certificates

To get details of the results of a completed sound insulation test, we will provide you with an analysis and report certificate. 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.

The way the results look

A certificate will be issued to you whether the sound insulation treatment of the building meets the requirements of Document E of Building Regulations or not. 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.
