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.

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. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. When the tests are completed, we work quickly to issue your certificates; we take great pride in our efficiency.

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 Insulation Testing Does

To adhere to Building Regulations ADE requirements, adjoining walls, floors and ceilings in a building will have to be tested, except where licensed Robust Details were 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.

What is part of a Sound Insulation Test

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. 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 dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.

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 full report and individual sound test certificates can be generated and sent out the next day. The sound testing guidelines are stipulated in Building Regulations ADE. It requires one set of test to be conducted on 10 units in a group or sub-group. You can find out what is meant by a sub-group in Section 1 of 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. How much testing that is required for each category can be found below.

Why Sound Testing is Required

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. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same 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.

Sound insulation and having privacy while speaking are crucial for a number of reasons. When sound insulation is deficient, it can cause discomfort to occupants. 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. 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?

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

Building Regulations Part E discusses sound testing in detail and has made it a requirement.

Either you follow the pre-completion sound testing process stipulated therein or you use Robust Details. This way, you have conformed to 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. 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. With sound testing, however, you’re free to pick from any design, including more cost effective and appropriate ones. This makes it a more efficient process than Robust Details. 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

Ideally, we would conduct a test when a development nears completion, and once all internal and external doors and windows have been fitted. We can test earlier to check if there are any 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.

The Process of a Sound 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 test uses a dodecahedron speaker and pink or white noise generator for source sound. The sound source is placed in the largest room of the two. The sound generated and received is measured with a sound level meter. The background noise level is also measured. The higher the background noise then the higher the source noise will need to be set, since the resulting noise level in the receiver room needs to be 10dB higher than the background noise at all measured 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.

This basic level difference is then ‘corrected’ to allow for the reverberation time (the time is taken, in seconds, for a noise source to decay by 60dB) and the existing levels of background noise monitored whilst in the receiving room. Impact sound tests are performed with a tapping machine positioned on the floor of the source room. The sound level in the room below it is recorded. Calculations are done and the outcome is checked against ADE requirements for the type of building. This is a simple way of explaining how a sound test is conducted.

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 a loudspeaker and noise generator that produces white or pink noise on one side of the partition, and measure with a sound level meter on both sides to calculate the sound insulation performance of the partition. We use a tapping machine, which drops metal hammers onto the floor to create impact noise. We then measure the amount of sound that passes through the partition with a sound level meter in the room under the tapping machine. The tests are administered in room with residential purposes. For example, kitchens/living spaces, lounges, bedrooms and living rooms. 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.

A sound test is mandatory for these buildings:

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 structure with 2 or more units/flats

This makes certain that the dwellings have adequate sound proofing.

Converting a property into several units

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

Designs without Robust Details

Robust Detail Ltd set up the Robust Detail Scheme in 2004 to make sure architect and building designs construct partition walls and floors that comply with Approved Document E sound insulation standards. If the building design does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building Regulations. The minimum criterion is based on various factors such as the purpose of the development and if it is a permanent dwelling or rooms to be used as residences like students’ accommodations and hotels.

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.

Building regulations document E resistance to the passage of sound (England and Wales)

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.

Building Standards Division (Scotland)

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.” 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.

Passing a sound insulation test

The most effective way to ensure you pass your sound test is to plan the project with sound insulation in mind. This does not need to be costly, and can save considerable time and expense at the end of the project, not to mention avoiding escalating remedial and re-test costs. If you are unsure of how to build the separating floor and wall constructions and associated junctions across your development to satisfy the requirements of Document E 2003, we can offer design advice. Our consultation may include several site visits and thorough design reports, or more basic initial tests on your structure. The following criteria should be followed to provide you with the best chance of passing your sound test: Install and make sure that all external and internal doors and windows are operational Skirting boards are fixed are sealed 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 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.

What the results look like

A sound insulation certificate will be sent to you whether the property has a good sound performance in accordance with ADE or not. 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.
