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. Part E of Building Regulations requires sound insulation in buildings and mandates that all newly completed constructions and rehabilitated developments go through sound testing.

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. We understand how important it is for you to get a sound insulation certificate. That’s why we go the extra mile to make sure you get your certificate as quickly as possible. We take great pride in providing our certificates to you as soon as possible after the tests.

Our highly capable sound test engineers will be available on site when you need them. They will give you a verbal result of the test, once taken and a written report will be issued to you by the following working day.

What Sound Testing Does

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. 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.

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

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.

A full and thorough report with the certificate of the test will be given to you within 24 working hours. Every 10 units in a group or sub-group are to be tested, according to ADE. A sub-group is stipulated in Section 1. Of ADE Buildings to be tested are categorised into three kinds: houses, flats and rooms like care homes, student accommodation and hotel rooms. How much testing that should be done on each group is listed below:

Why is Sound Insulation Testing Relevant?

Document E of Building regulations, from 2003, made it compulsory for all new UK constructions to undertake a pre-completion sound test. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. 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. When sound resistance is high in party walls and floors, the environment is more comfortable, since sound affects every aspect of our lives – work environment, home environment and while relaxing. This is why sound testing is crucial.

Sound insulation and speech privacy are important because not having them results in an unfavourable environment for those living in the development. 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. Sound insulation helps improve the quality of a person’s life in diverse 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.

Does Your Development 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

It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.

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 design details for walls that were tested formerly and meet the sound performance parameters stated by Part E of Building Regulations. Using Robust Details, without taking a test, limits you to the design you’ve picked. Being able to adapt your design to suit your needs is more efficient and costs less in the long run. 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 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. 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 Procedures of a Sound Insulation Test

The method of taking the test is not complex and our sound test engineers can explain it thoroughly on site, if you wish. 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 sound in the source room and receiver room (sharing a separating wall with the source room) 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 tests are conducted in this manner: two singular speaker positions are used for every source room. The noise in the receiver room is measured to determine the variations in noise level between the source and receiver room.

Finally, the difference in noise level is modified to accommodate reverberation time and background noise that was already in the receiver room. Reverberation time is how long it takes sound to decay by 60dB. Impact tests are conducted by fixing a tapping machine on the floor. The sound pressure level at the receiving room, which is below the source room, is measured. Once the calculations are completed and the result is achieved, it is compared with Building Regulations Part E standards. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.

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. An airborne sound test measures levels of sound transmitted through the air through a separating element. Equipment used for the test include a noise generator, speakers and sound level meter. 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 compiled in a report and issued to the client. The report will be accepted by Building Control and used for signing off your project.

These kinds of properties should undergo a sound insulation test:

Sound testing measures the impact and airborne sound moving through new and old adjoining buildings. This could affect the separating walls between buildings or in-between the spaces in a development.

Property with two or more units

This makes certain that the dwellings have adequate sound proofing.

Converting a single development to flats

All the units that have been built are to be constructed in alignment with Part E of Building Regulations.

Design that don’t have Robust Details factored in

Robust Details Ltd began the Robust Details scheme in 2004. The scheme enables architects use design details for separating elements, which have been tested before to comply with Document E standards. If the design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. 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.

Building regulations for sound insulation test

We provide sound testing and sound insulation testing on all types of buildings, for compliance with Part E Building Regulations in England and Wales and Section 5 of the Scottish Building Standards. Testing can also gain credits for Code for Sustainable Homes and EcoHomes environmental assessment schemes.

Sound resistance and performance: Document E of Building Regulations (England and Wales)

Our expert engineers can issue certificates for the sound insulation testing. They can visit the site and conduct the test that will lead to getting a certificate which is in line with Building Regulations and Building Control requirements.

Scotland Standard division for completed constructions

According to 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.” Tests, which are conducted after building utilizing the methodology given in annex 5.C. of the Scottish Standard 5.1 does not apply to: completely disconnected houses, rooftops and walkways with access exclusively for the use of the occupants of the home underneath.

How to get a pass certificate for 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. Whether you want some initial tests on your project, or comprehensive reports at the end, we can help you at the level that you need. The following conditions will provide you with an ample chance of passing the sound test: Windows and internal and external doors are fitted and operable Fit and seal skirting boards 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.

Test report certificates

After the test, AF Acoustics’ competent and well trained engineers can let you know the verbal results of your sound test and provide feedback on issues noticed during the test. We endeavour to send an investigation and report certificate 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 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. If parts or all the building fails the test, repair work and a retest is recommended. We provide design advice to ensure your property does proper remedial and meets up with the necessary 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.

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.
