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 has been a mandatory part of the Building Regulations for new build and refurbishment projects since Approved Document E (ADE) was revised 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 know how important a sound insulation certificate is to you. That is why we work hard to make certain that you get the certificate quickly. 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 is a Sound Insulation Test?
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 testing measures the impact and airborne sound moving through new and old adjoining buildings. This tests include the boundary walls between buildings and in-between the spaces in a development.
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. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. A structure that is simple and the conventional size will usually take 90 minutes to be tested.
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 and thorough report with the certificate of the test will be given to you within 24 working hours. 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. Find below the testing stipulation for each kind of development.
Why Sound Testing is Required
Before completing a building, all new constructions should be tested for sound insulation, as stipulated by Approved Document E since 2003. The impact sound test result should not be more than 62dB L’nTw and the airborne sound insulation should not be less than 45dB DnTw+Ctr. These result limits were put in to create and maintain a uniform standard for sound resistance in different parts of a dwelling and between adjacent buildings. 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. 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. 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 Do I Know if I Need a Sound 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.
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 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. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. 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. It also gives architects the opportunity to evaluate their design and give your structure a much better sound insulation which will increase sound performance.

When Should the Sound Tests be done?
The best time for a sound insulation test is just before the construction of the property is finished and after all windows and doors are fixed. However, in the case of a problem we can take the test before then. 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.
How a Sound Test is Done
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.
A pink or white noise generator and a large speaker is used for the test in the biggest room between the two undergoing 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. Airborne sound tests are conducted in this manner: two singular speaker positions are used for every source room. The noise in the receiver room is measured to determine the variations in noise level between the source and receiver room.
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 tests are done by placing a standardised tapping machine on the floor. The sound pressure level at the receiving room, which is below the source room, is measured. Once the calculations are completed and the result is achieved, it is compared with Building Regulations Part E standards. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
Sound Test Equipment Used
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. Airborne sound test is the measurement of sound moving through the air through a wall or floor. The equipment we use are a sound level meter, loudspeaker and white or pink noise generator. Sound level meter is also used for impact tests. Alongside it, a tapping machine that drops metal hammers is used. 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.
These kinds of properties should undergo a sound insulation test:
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 sure that the sound insulation for the building meets all the necessary requirements.
A single dwelling that was turned into a development with several flats or units
All the units that have been built are to be constructed in alignment with Part E of Building Regulations.
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 design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. 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.
