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. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo sound testing.
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. 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. We take great pride in providing our certificates to you as soon as possible after the tests.
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 completely fulfil Building Regulations Part E requirements, the separating walls and floors of dwellings will be tested, unless approved Robust Details are used. 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.
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. 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.
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 also states the categories of developments that should be tested. There are three: rooms, flats and houses (including bungalows) that are lived in. Examples are student accommodation, hotel rooms and care homes. How much testing that should be done on each group is listed below:
Why is Sound Insulation Testing Required? Why is it Important?
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. Results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. 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. 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.
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. 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 example of how sound insulation can affect the quality of life of people in different ways. There are also developments where the neighbouring units are used for different purposes. In such cases, a sound test ensures that the noise coming from each unit is minimal.
Does Your Development 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
Document E of the Building Regulations explains sound insulation testing and makes it a necessity.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. Robust Details are design details for separating elements, which have been tested before to comply with Document E standards. The Robust Details scheme means that testing is not necessary, but is strictly limited to the design given in the Robust Details approved list. Being able to adapt your design to suit your needs is more efficient and costs less in the long run. It also gives architects the opportunity to evaluate their design and give your structure a much better sound insulation which will increase sound performance.

Sound Insulation Test Time
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. 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 Done?
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.
The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. The sound in the source room and receiver room (sharing a separating wall with the source room) is measured with a sound level meter. 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. 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.
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 sound level in the room below it is recorded. 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. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
What Sound Insulation Testing Equipment do we use?
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. An airborne sound test measures levels of sound transmitted through the air through a separating element. Equipment used for the test include a noise generator, speakers and sound level meter. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. The tests are administered in room with residential purposes. For example, kitchens/living spaces, lounges, bedrooms and living rooms. The outcome of the test is written in a report and sent to the customer. This report helps Building Control sign off your building.
Sound insulation testing is essential for these dwelling types:
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 new building with not less than two rooms
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 development that has been converted must conform to Building Regulations sound requirements.
Design that don’t have Robust Details factored in
The Robust Details scheme was set up in 2004 by Robust Details Ltd as a way to help architects and builders design and construct separating elements with the confidence that the separating wall and/or floor will be capable of achieving the sound performance parameters in Approved Document E, and comply with the Building Regulations. If the building design is slightly different from Robust Details, a sound test is essential so that Building Regulations criteria can be met. The minimum requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.

Our certified engineers can come to your building whenever it might suit you to undertake sound insulation testing to Part E of Building Regulations adherence, recognised by Building Control.
Building Standards Division (Scotland)
Section 5.1 of the Scottish Building Standards explicitly describes expected energy performance of dwellings. It states, “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 taken at the completion of the building, using procedures given in annex 5.C. of the Scottish Standards. These standards don’t apply to detached structures that have access only for maintenance or are to used only by the occupants who live below.
How to get a pass certificate for your sound 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. Are you uncertain that the separating floor and walls you will build will adhere to Document E 2003 conditions? You can book our design services. We can study design reports, complete site visits and sound test the development to provide you with the level of assessment and consultation that your project requires from start to finish. The following criteria should be followed to provide you with the best chance of passing your sound test: Windows and internal and external doors are fitted and operable Skirting boards are fixed are sealed Light fittings and switches and plug sockets are fitted and working.
