The measurement of the sound reduced by partitions in a development, such as a wall or floor, is known as sound insulation testing or sound testing. It assesses how good the soundproofing materials fixed to the property development are. 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.

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. 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.

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.

How Sound Testing Works

Developments must test all walls, floors and ceilings that separate buildings or neighbours in a dwelling, to conform to Approved Document E (ADE) of the Building Regulations. You may not have to test your building if you used Robust Details which were approved before their installation. Sound testing measures the impact and airborne sound moving through new and old adjoining buildings. This tests include the boundary walls between buildings and in-between the spaces in a development.

What is involved in Sound testing?

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. If the site is simple and of regular size, it typically takes about 90 minutes to complete the sound test.

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.

The entire report and individual sound test certificate will be sent to you the day after. 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 are divided into three kinds for the test – houses, flats and rooms built for or converted to residential dwellings, like student accommodation, care homes and hotel rooms. The volume of testing carried out on each group is written below.

Why Should Your Dwelling Undergo Sound Testing

Document E of Building regulations, from 2003, made it compulsory for all new UK constructions to undertake a pre-completion sound test. 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. 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 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.

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. 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. 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?

You need a sound insulation test if you’re:

  • Constructing a nursing home or residential rooms like hostel or hotel rooms,
  • Converting a building with a single dwelling into flats,
  • Constructing a property with two or more units,
  • Using designs without Robust Details to build

Document E of the Building Regulations explains sound insulation testing and makes it a necessity.

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. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. 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 can I carry out the sound insulation tests?

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. During the test, you should provide the following:

  • Access to all rooms. The only exception is if a schedule was created before the test time.
  • 240V power supply
  • A noiseless site

The Process of a Sound Test

Our sound test engineers can answer your questions and make the sound test process easy to understand on site, during the time of the test. We carry out airborne and impact tests on separating floors, and airborne tests on separating walls.

The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. The noise from the source room and received by the receiver room, and background noise is measured with a sound level meter. 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. 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.

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 carried out by means of a tapping machine placed on the floor to be measured. The sound pressure level at the receiving room, which is below the source room, is measured. Calculations based on these measurements are undertaken and the results compared to the Building Regulations Part E requirements for the given type of the building. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.

Sound Test Equipment Used

You can expect UKAS calibrated equipment from us, as stipulated by Building Regulations. Our certified engineers conduct tests to meet the current guidelines. The calculation of the level of noise transmitted through the air between two adjoining units is known as an airborne sound insulation test. A loudspeaker and noise generator is used in one room while a sound level meter is used in both rooms for measuring level of noise. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. Testing can only be completed on ‘habitable’ rooms. Habitable rooms can be bedrooms, lounges, living rooms and open plan kitchen/ living spaces. Test findings are compiled in a report and issued to the client. The report will be accepted by Building Control and used for signing off your project.

Sound Insulation Testing is necessary for these types of builds:

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.

Two or more new build dwellings or flats

This ensures that a sound insulation system installed in residences meets the requirements of ADE.

A single dwelling that was turned into a development with several flats or units

The development that has been converted must conform to Building Regulations sound requirements.

Design not using 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. The minimum requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.

Airborne and impact tests for floors/ceilings

These are taken on separating floors/ceilings between residences. The calculation of the sound level transferred from one unit to another through a separating floor via impact is called an impact test. Airborne and impact tests are conducted on the floor partitions between liveable rooms.

ADE testing

Our sound tests align to Part E of Building Regulations guideline, which thoroughly describes sound resistance level and performance from structures. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result for newly completed constructions. On the other hand, 64dB L’nTw or less impact sound and 43dB DnTw+Ctr or higher airborne sound insulation is expected from refurbished buildings.

Sound test

Our services and expertise is unbeatable and we are glad to work with our clients to help pass their sound insulation tests. To make sure a new residence meets with the standards of greater than 45dB DnTw+Ctr and less than 62dB L’nTw, an airborne wall test and an airborne and impact floor test will need to be conducted.

Part E of building regulations resistance to the passage of sound (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 to get a pass certificate for your sound 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. We offer design services that help you construct separating walls and floors with good sound performance that meet ADE demands. We can study design reports, complete site visits and sound test the development to provide you with the level of assessment and consultation that your project requires from start to finish. 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 Fix all light switches, light fittings and plug sockets. Our expert acoustic consultants work with planners, developers, architects and contractors from the beginning of the design stage till when the property is finished to ensure it meets the conditions of Document E 2003.

Certificates for test evaluation and report

To obtain a thorough evaluation of your building, we issue a report certificate within 24 working hours where possible. Our highly capable sound test engineers will give you a verbal result of the test, once the test is taken and proffer solutions to possible problems 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.

The results

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 of a wall or floor not achieving the Part E requirements, it may be necessary to carry out remedial works before having another sound test carried out. We can provide you with remedial design advice to help you achieve the Building Regulations requirements.


Sound Insulation FAQ’s

The minimum requirements depend on a variety of factors such as if the development is a new build or refurbished, whether the development is intended to be a permanent dwelling, or classified as “rooms of residential purposes” (e.g. hotels, student accommodation, etc).

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.

Flanking sound (or flanking noise) is sound that transmits between spaces indirectly, going over or around, rather than directly through the main separating element. This can allow sound to transmit between spaces even though the main separating element itself provides good acoustic insulation. Engaging our services at an early stage allows us to check designs and add necessary measures to prevent this occurring after construction. In the worst cases, flanking can exceed the direct transmission and lead to a failed test, despite highly specified partitions.

In the case of impact sound, the building construction is caused to vibrate as a result of a physical impact, such as footsteps on floors or stairs. The resulting vibration is radiated into other rooms in the building.

We can provide preliminary results on the day of test. We strive to deliver next day reporting in all scenarios regardless the complexity or size of the project. The delivered report will be comprehensive and detailed, to ensure all relevant issues are covered. The best recommendations can also be sent in a separate report or email.

We can normally conduct up to a maximum of three sets of tests per day. One set is two airborne floor tests, two airborne wall tests and two impact floor sound tests.

When it comes to the acoustic tests, a full set of tests should take approximately 90 minutes.

The requirements of sound insulation testing are fully detailed in the Building Regulations Approved Document, available here [link], under Part E (2003).

This requires all residential buildings to be tested when they involve walls and/or floors. These are known as party elements.

Assuming no tests are failed, building control bodies should stipulate at least one set of tests for every ten dwelling-houses, flats or rooms for residential purposes in a group or sub-group.

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.

We recommend that if possible, we are contacted before a build to provide a design review and advice on how to meet quality standards.

Should the test fail, we can offer advice on how to improve the sound insulation. We have consulted on hundreds of building projects in the past, and have ensured all of them have met the building regulations. If a sound insulation test fails, we can give remindial advice to ensure the tests passes later.

We understand that most clients would prefer testing to take place as soon as possible. Once you get in touch we will schedule the test at the earliest available opportunity.

You can call us today to set up an appointment for sound insulation testing. Our scheduling is flexible so that you can get the service you need at your convenience.

Ideally, a test should be carried out as early as possible as problems are more difficult to fix the further along you are. Where possible, it’s recommended that testing is carried out before kitchens or bathrooms are installed. The minimum that we require to be able to carry out a test is:

  • All doors, windows and seals should be fully fitted and closable
  • All electrical fittings should be fitted and working
  • 240V mains power must be available on-site in all rooms
  • Gaps in walls and floors should be fully sealed
  • All walls and ceilings should be plastered
  • There should be no holes remaining in floors or ceilings
  • Testers will require access to all rooms on all levels

Pre-completion sound testing is a building regulation requirement for all purpose built & “formed by material change of use” (i.e. refurbished) properties since 2003. Sound testing is undertaken in a percentage of properties in each development to ensure that the separating walls & floors between habitable rooms of neighbouring properties meet the minimum requirements as defined by Approved Document E, commonly referred to as ADE.

From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. New builds must achieve impact sound test results of no more than 62dB L’nTw and airborne sound loss of no less than 45dB DnTw+Ctr. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound loss of no less than 43dB DnTw+Ctr. Approved Document E sets out details pertaining to the resistance to the passage of sound.

This Approved Document, as part of UK Building Regulations helps to ensure that newly built or converted houses and residencies, flats and residential spaces and other relevant buildings are constructed to minimum standards that provide ‘reasonable resistance to sound from other parts of the same building and from adjacent buildings.’ All of our tests are fully compliant with Approved Document E and our expert team have been carrying out compliant tests for many years, for thousands of satisfied customers throughout the UK.

We understand the sectors our clients work in. Our advice is not only technically robust but also practical and helpful to our client’s particular situation. At AF Acoustics, we always look at the bigger picture and work towards the ultimate development goal.

Our consultants are very experienced and have a proven track record on both small scale projects and major projects. As we are a lean and small company, we have lower overheads and therefore offer exceptional value for money.

Airborne sound (or airborne noise) is sound that is transmitted through the air. Airborne Sound Insulation is the insulation against noise originating in air, e.g. voices, music, motor traffic, wind. The greater the airborne sound insulation between two rooms, the lower the resulting sound level in the receiving room.

This is unlike Impact Sound Insulation that protects against noise originating directly on a structure by blows or vibration e.g. footsteps above, furniture being moved, drilling and hammering the structure.
