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. It is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated 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 pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.

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.

How Sound Testing Works

To completely fulfil Building Regulations Part E requirements, the separating walls and floors of dwellings will be tested, unless approved Robust Details are 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 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. Sound insulation testing varies by size, complexity and conditions of site tested. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.

Once it is completed, the engineers will give a verbal interim result on the site and basic helpful information on what was noticed during the test, e.g. possible sound issues and future places that could cause problems.

A complete report and sound insulation test certificate can be produced and issued 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). There are three types of grouping criteria that need to be assessed: dwelling houses (including bungalows), flats and rooms for residential purposes, such as student accommodation and hotel rooms, care homes etc. The extent of testing required for these three groups is shown below.

Importance of Sound Insulation Testing

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. Results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same 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 critical for a variety of reasons. Inadequate sound insulation can be extremely distressing to those affected by it. Let’s take a look at this scenario. An individual living in a block of flats might spend the weekend with friends relaxing and playing loud music. If the sound insulation on adjoining walls and floor is insufficient, the music will be distressful to neighbours, especially if they work at night. This is just one example of how sound insulation can affect the quality of life of people in different 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.

Do I 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 separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. Using Robust Details, without taking a test, limits you to the design you’ve picked. 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. Conducting on-site pre-completion sound testing also enables the architects more scope with their design and can lead to improved sound insulation performance.

Sound Insulation Test Time

The ideal period for a sound insulation test is after the fitting of windows and doors, and before the building is finished. If you want, AF Acoustics can conduct tests before then to find out if there are any problems on your property. 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 Procedures of a Sound Insulation Test

The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.

The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. A sound level meter calculates the noise in the source room and 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.

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 carried out by means of a tapping machine placed on the floor to be measured. The sound level in the room below it is recorded. 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. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing 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. An airborne test is used to check how much sound is moving through the air between partitions. 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. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. Test results, which are approved by Building Control and used to sign off the building, are recorded in a report and sent to the client.

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.

Property with two or more units

This makes certain that the dwellings have adequate sound proofing.

Converting a property into several units

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

Design that don’t have Robust Details factored in

The Robust Details scheme was set up in 2004 by Robust Details Ltd as a way to help architects and builders design and construct separating elements with the confidence that the separating wall and/or floor will be capable of achieving the sound performance parameters in Approved Document E, and comply with the 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.

Our certified engineers can come to your building whenever it might suit you to undertake sound insulation testing to Part E of Building Regulations adherence, recognised by Building Control.

Scotland Standard division for properties

Section 5.1 of the Scottish Building Standards stipulates that “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.” The following are exempt from the testing techniques given in annex 5.C. of the Scottish Standard and Standard 5.1 – completely segregated rooftops, houses or walkways whose access is only used for upkeep or for the utilization of the inhabitants of the dwelling beneath.

How Do I Pass a Sound Insulation 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. We offer design services that help you construct separating walls and floors with good sound performance that meet ADE demands. Our consultation may include several site visits and thorough design reports, or more basic initial tests on your structure.

Certificates for test evaluation and report

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 report and individual sound test certificates can be generated and sent out usually 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.

How the results are

You will get your sound insulation test certificate whether you pass or fail the sound tests. We can provide professional advice on designs that will surpass Document E standards if the building fails the test.
