Sound insulation testing involves the use of specialist equipment to examine how much sound is reduced off by floors and walls, of a building. It checks if a dwelling’s sound proofing treatment meets the requirements set out in Approved Document E. 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. 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. In fact, we pride ourselves on issuing our sound insulation testing certificates as quickly as possible.

AF Acoustics’ competent and well-trained engineers, who will be available for testing, can even let you know the verbal results of your sound test. You will receive a written report in the space of a working day.

What Sound Insulation 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 Insulation Testing tests for both the airborne sound and the impact sound which travels through new or existing buildings . The tests cover party walls and floors between new and existing buildings, or between spaces within a new development entirely.

What is involved in Sound Insulation 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 process of a sound test is determined by the size and complexity of the site being tested. If the site is simple and of regular size, it typically takes about 90 minutes to complete the sound test.

After the test, the sound insulation test engineers will let you know the outcome of the test and supply simple feedback of important things noted during the test; e.g. problems that might occur in the future.

You will get a detailed written report and sound test certificate about a day after, if possible. 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 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

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

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. 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. 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?

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

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

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. When you use it, you don’t have to take a sound insulation test. However, you must abide strictly by the design from the Robust Details approved list. This becomes difficult when you need to pick a more appropriate or cost-effective design that will suit your needs. Sound tests enable you do that, making it more flexible. On-site pre-completion sound insulation testing gives architects more insight and ability to make their design lead to constructions that have a higher sound 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. 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

How a Sound Test is Done

The method of taking the test is not complex and our sound test engineers can explain it thoroughly on site, if you wish. The boundary floors and walls get airborne tests. Floors get an additional impact test.

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. 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.

The sound difference is adjusted to make an allowance for reverberation time (time in which the sound decays by 60dB) and background noise in the receiver room. Impact tests are carried out by means of a tapping machine placed on the floor to be measured. The room under it is then measured for the noise levels. 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. Of course, this is a simple way of describing the procedure followed when a sound test is carried out, but it enables you to understand it better.

Kind of Testing Equipments Used

You can expect UKAS calibrated equipment from us, as stipulated by Building Regulations. Our certified engineers conduct tests to meet the current guidelines. Airborne sound test is the measurement of sound moving through the air through a wall or floor. Equipment used for the test include a noise generator, speakers and sound level meter. 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 findings are fed into a report that will be sent to the client. This report will always be acceptable to Building Control and will help you to get your development signed off.

It’s important to undertake a sound test if you have this kind of building:

Sound insulation tests examine airborne and impact sound moving through buildings. It is usually undertaken between party walls and floors between 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.

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 not using Robust Details

Architects are able to use pre-tested and approved Robust Details design for partitioning walls and floors. The Robust Details scheme was formed in 2004 by Robust Details Ltd. If the building design does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building Regulations. 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.

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

We have fully accredited engineers who can visit your property to issue appropriate certification that complies with the building control.

Standard division for developments (Scotland)

In the words of 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.” 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.

Passing a sound insulation 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. Our consultation process is led by your project requirements and may include assessment of design reports, test of the development and multiple site visits. The following will give you a better chance of passing the sound test: Windows and internal and external doors are fitted and operable Skirting boards are fixed 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.

Investigation 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.

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. 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.
