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.

Not doing so is a costly venture for developers and contractors as Building Control will not give a completion certificate for developments that have not undergone the test. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. We take great pride in providing our certificates to you as soon as possible after the tests.

Our highly qualified site engineers can arrive on site when needed. They will provide verbal results after the test and a written report will be sent to you within 24 working hours.

What Sound Testing Does

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 Insulation Testing

A sound insulation test creates a high amount of noise but needs a site with low noise levels to be taken effectively. As a result of this, workers in a testing area might have to leave the development temporarily, so that the test can be free from errors. 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.

A full and thorough report with the certificate of the test will be given to you within 24 working hours. 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.

Why is Sound Insulation Testing Required? Why is it Important?

Sound insulation testing is required because ADE of Building Regulations has made it compulsory for all new buildings to take a sound test prior to finishing construction. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. This is to be certain that all new developments meet a uniform minimum criterion for resistance to sound from other parts of the development and adjoining developments. Testing for sound insulation is vital because sound influences how we live in the office, while relaxing or in the house. Restricting the sound that moves between floors and walls could result in a more relaxed and better surrounding.

Sound insulation and speech privacy are important because not having them results in an unfavourable environment for those living in the development. 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. Sound insulation is also effective in buildings that have flats with mixed uses. If the building passed the sound test, you can be sure that noise reduction will be effective.

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.

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. 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 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.

Sound Insulation Test Time

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. 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.

How a Sound Test is Done

Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.

A big or multidirectional speaker, with a generator of pink or white noise is used to the biggest room. The noise from the source room and received by the receiver room, and background noise is measured with a sound level meter. 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. 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.

This difference is modified to include background noise in the receiver room and reverberation time – time whereby a sound fades away in a closed space by 60dB. Impact tests are done by placing a standardised tapping machine on the floor. The noise level is then recorded in the room below. 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.

Type of Sound Insulation Test Machines We Will be using

Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of 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. The equipment we use are a sound level meter, loudspeaker and white or pink noise generator. For impact test, a tapping machine that makes impact sound by dropping metal hammers is used. A sound level meter is used to measure in the receiving room below the room the tapping machine is in. The tests are administered in room with residential purposes. For example, kitchens/living spaces, lounges, bedrooms and living rooms. The outcome of the test is written in a report and sent to the customer. This report helps Building Control sign off your building.

Sound insulation testing is essential for these dwelling types:

Sound Insulation Testing checks for both airborne and impact noise travelling through new or existing buildings. This may affect party walls and floors between new and existing buildings, or between spaces within a new development.

A structure with 2 or more units/flats

This makes sure that the sound insulation for the building meets all the necessary requirements.

Conversions of former single dwelling properties into flats

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

Using designs where Robust Details are not included

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 does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building 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.

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.

Standard division for developments (Scotland)

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 should be performed after construction, using the procedures given in annex 5.C. of the Scottish Standards. Standard 5.1 does not apply to: fully detached houses or roofs or walkways with access solely for maintenance, or solely for the use of the residents of the dwelling below.

How to pass a 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. Are you uncertain that the separating floor and walls you will build will adhere to Document E 2003 conditions? You can book our design services. 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: All windows and door have been fixed and are functioning Skirting boards are fixed are sealed Light switches, light fittingsand plug sockets are properly fitted 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.

Certificates for test evaluation and report

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.

The results

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 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.


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.
