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.

As many contractors and developers have found to their detriment, without a sound insulation certificate, the Building Control Officer will not issue a completion certificate. We understand how important it is for you to get a sound insulation certificate. That’s why we go the extra mile to make sure you get your certificate as quickly as possible. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.

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 is a Sound Insulation Test?

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 insulation tests examine airborne and impact sound moving between separating walls and floors. The tests include party walls and floors between structures or between spaces within a new development.

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 this is done, the sound test engineers give temporary results while they’re still on the site. They will also provide suggested solutions to possible problem areas noted during testing.

A full report and individual sound test certificates can be generated and sent out the next day. 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 are divided into three kinds for the test – houses, flats and rooms built for or converted to residential dwellings, like student accommodation, care homes and hotel rooms. How much testing that is required for each category can be found below.

Importance of Sound Insulation Testing

Before completing a building, all new constructions should be tested for sound insulation, as stipulated by Approved Document E since 2003. 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. 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 impacts people’s lives in various 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.

How to Know if You Need Sound Insulation Testing

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

ADE thoroughly explains sound testing and makes it compulsory.

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 separating elements, which have been tested before to comply with Document E 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. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.

Period Sound Insulation Test Should be Carried Out

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. 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

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. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.

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. A sound level meter is then used to take noise measurements within the source room and the receiver room. The meter is also used to measure the background sound, to ensure that it’s 10dB lower than the source sound, as is the standard. More background sound leads to creating a higher source sound. 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.

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 conducted by fixing a tapping machine on the floor. The sound pressure level at the receiving room, which is below the source room, is measured. Calculations are done and the outcome is checked against ADE requirements for the type of building. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.

Kind of Testing Equipments Used

Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. An airborne sound test measures levels of sound transmitted through the air through a separating element. 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. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. Testing is done on rooms that can be lived in. E.g. lounges, kitchens, 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.

Sound Insulation Testing is necessary for these types of builds:

Sound testing measures the impact and airborne sound moving through new and old adjoining buildings. This could affect the separating walls between buildings or in-between the spaces in a development.

Property with two or more units

This is to ensure that the sound proofing of the building is up to standard for residential purposes.

Converting a property into several units

When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.

Designed in a way that does not adhere to 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. Once the design does not strictly abide by the design from Robust Detail approved list, the structure will have to undergo a sound test to ensure it conforms to 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.
