The measurement of the sound reduced by partitions in a development, such as a wall or floor, is known as sound insulation testing or sound testing. It assesses how good the soundproofing materials fixed to the property development are. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo sound testing.

Not having a sound insulation certificate issued after a test, has resulted in additional costs and expenses for developers. Any development that has not taken a sound test will not be given a completion certificate by Building Control. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. In fact, we pride ourselves on issuing our sound insulation testing certificates as quickly as possible.

Even before you get the certificate, you will receive the results of the test. First, our skilled and competent sound insulation test will engineers give you a verbal result at the site. Then, a written report is sent to you within 24 hours of a working day.

What Sound 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. 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.

The Procedures Involved in 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. Sound insulation testing varies by size, complexity and conditions of site tested. Most of the time the test will be conducted in 90 minutes, for a simple, regular sized construction.

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.

The entire report and individual sound test certificate will be sent to you the day after. 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. 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 Relevant?

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 Approved Document, as part of UK Building Regulations helps to ensure that new buildings are constructed to minimum standards that provide reasonable resistance to sound from other parts of the same building and from adjacent buildings. Sound insulation testing is important because sound affects the way we live, whether at work, in the home or whilst at leisure. Noise reduction between walls and floors could result in a more comfortable, productive environment.

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. 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. Sound insulation helps improve the quality of a person’s life in diverse ways. It can be useful in dwellings with neighbouring units/flats/rooms which have diverse purposes, by guaranteeing that an occupant in a room will hear as little noise as possible from the neighbouring room.

Do You Need a Sound Test?

Your development needs a sound insulation test if it meets one of the following criteria:

  • It’s design does not have Robust Details
  • It’s a new building with 2 or more dwellings
  • It’s being constructed to be used as a residence, like a hotel room or a hostel, or as a nursing home
  • It was once a single dwelling but is being turned into a development with several flats or units.

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 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. 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. 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.

Ideal Period for a Sound Insulation Test

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. These are the things we need to conduct the test:

  • 240V power supply
  • A quiet environment
  • Access to all the units of the structure unless places to test have been decided before then.

How a Sound Test is Done

Our sound test engineers can answer your questions and make the sound test process easy to understand on site, during the time of the test. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.

The airborne sound insulation test is carried out with a large speaker or dodecahedron speaker, using a white or pink noise generator to create the source sound, almost always in the largest room of the two rooms under testing. The sound generated and received is measured with a sound level meter. 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. For airborne tests, two speakers positions are used in the source room and the level of noise entering into the receiving partition room is measured. That way the difference in sound level is calculated.

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 room under it is then measured for the noise levels. This is used in calculating and computing the results. These results are checked against Building Regulations ADE conditions for that kind of dwelling. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.

Type of Sound Insulation Test Machines We Will be using

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. We use pink or white noise generator and speakers on one side of the partition. A sound level meter is used on calculating sound in both units. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. Testing can only be completed on ‘habitable’ rooms. Habitable rooms can be bedrooms, lounges, living rooms and open plan kitchen/ living spaces. 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.

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.

Property with two or more units

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

Conversions of former single dwelling properties into flats

When the development is completed, ADE of Building Regulations should be checked, and sound insulation tested accordingly.

Design not using Robust Details

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 building design is not in line with any Robust Details, it will require sound testing to ensure its compliance with the buildings 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.

The adjoining floors/ceilings of rooms intended as residences usually have both impact and airborne sound tests.

PART E Testing

Document E of Building Regulations requires certain criteria for the sound performance of a dwelling. Our sound insulation tests are conducted in accordance to these criteria. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result for newly completed constructions. On the other hand, 64dB L’nTw or less impact sound and 43dB DnTw+Ctr or higher airborne sound insulation is expected from refurbished buildings.

Sounds test in accordance with building regulations

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.

Part E of building regulations resistance to the passage of sound (England and Wales)

We can have fully accredited engineers sent to your property at your convenience to provide certification for Building Regulations Part E compliance, recognised by Building Control.

Standard division for structures (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.

Passing 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 to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. The degree of guidance you require can vary, from site visits and comprehensive design reports, to simpler initial testing to know the starting point for construction. The are required in order to have good conditions to undertake the sound insulation tests: All windows and door have been fixed and are functioning Skirting boards are fixed Fix all light switches, light fittings and plug sockets. 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

To obtain a thorough evaluation of your building, we issue a report certificate within 24 working hours where possible. Our highly capable sound test engineers will give you a verbal result of the test, once the test is taken and proffer solutions to possible problems or future areas of concern. 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

You will get your sound insulation test certificate whether you pass or fail the sound tests. In the event that some part of the building does not meet up with the conditions of Document E, remedial work and a retest is required. We give remedial design advice to help you achieve Building Regulations standards.
