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 is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated 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. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
Our fully trained sound insulation test engineers can be on site when you need them. Your AF Acoustics engineer will give you immediate verbal results from the sound test, and you can will have a written report by the following working day.

What is a Sound Test?
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.
What is involved in Sound testing?
Workers on a site will vacate the premises while the sound test is being conducted. This will facilitate an enabling and quiet environment for the tests to be carried out. 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.
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.
You will get a detailed written report and sound test certificate about a day after, if possible. 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 should be done on each group is listed below:
Why is Sound Insulation Testing Required? Why is it Important?
Document E of Building regulations, from 2003, made it compulsory for all new UK constructions to undertake a pre-completion sound test. New builds must achieve impact sound test results of no more than 62dB L’nTw and airborne sound insulation of no less than 45dB DnTw+Ctr. The aim of Approved Documet E of the Building Regulations is to establish a minimum standard for the reduction in noise levels between all dwellings in a new or refurbished building. When sound resistance is high in party walls and floors, the environment is more comfortable, since sound affects every aspect of our lives – work environment, home environment and while relaxing. This is why sound testing is crucial.
Insufficient sound insulation causes distress and comfort while an effective sound insulation system brings about speech privacy. This is one of the several reasons why sound insulation is a key element in building. 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. This is just one instance of the influence of sound insulation on our lives. 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.
How to Know if You Need Sound Insulation Testing
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. It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
All you have to do is follow the guidelines listed in the document or pay to use Robust Details and you will have fulfilled 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 can I carry out the sound insulation tests?
The ideal period for a sound insulation test is after the fitting of windows and doors, and before the building is finished. If you want, AF Acoustics can conduct tests before then to find out if there are any problems on your property. For your sound tests to be conducted successfully we need the property to be quiet, with workers not near the rooms to be tested during the test time (a noisy environment makes the test difficult and sometimes unsuccessful). We also need access to all units unless the test program has been compiled earlier. Finally, we need 240V power supply.
How is sound insulation testing carried out?
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.
The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. A sound level meter calculates the noise in the source room and receiver room. Noise in the background is also calculated. More noise in the background means a higher level of source sound will be created since it’s supposed to be 10dB higher than background noise on all calculated frequencies. 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 difference is modified to include background noise in the receiver room and reverberation time – time whereby a sound fades away in a closed space by 60dB. Impact tests are done by placing a standardised tapping machine on the floor. The room under it is then measured for the noise levels. Once the calculations are completed and the result is achieved, it is compared with Building Regulations Part E standards. 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.
Sound Testing Equipment to Expect
Our high-tech sound insulation machines are UKAS calibrated and our accredited expert engineers conduct the test using Building Regulations present criteria. Airborne sound test is the measurement of sound moving through the air through a wall or floor. 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. 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. You will get the test results in a report within a working day. This report can be used to help sign off your building as it is accepted by Building Control.
It’s important to undertake a sound test if you have this kind of building:
Sound Insulation Testing checks for both airborne and impact noise travelling through new or existing buildings. This may affect party walls and floors between new and existing buildings, or between spaces within a new development.
A structure with 2 or more units/flats
This ensures that a sound insulation system installed in residences meets the requirements of ADE.
Redevelopment of a building with a single dwelling into flats
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Design that don’t have Robust Details factored in
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. 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.
