Sound testing calculates the extent to which sound is blocked by the partition (walls, floors etc) of a building between dwellings. It evaluates the efficiency of the soundproofing materials that make up the structure. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo sound testing.
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. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. We pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.
Our highly qualified site engineers can arrive on site when needed. They will provide verbal results after the test and a written report will be sent to you within 24 working hours.

What Sound Testing Does
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 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.
The Procedures Involved in a Sound Insulation Test
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. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.
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.
You will get a detailed written report and sound test certificate about a day after, if possible. The way a sound test is conducted is determined by ADE of Building Regulations. It mandates that in all developments, every 10 units in a group or sub-group will undertake one set of tests. It explicitly states what a sub-group is in Section 1. 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 is required for each category can be found below.
Why Should Your Dwelling Undergo Sound Testing
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. 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 testing is essential due to the fact that sound impacts us wherever we are, whether it’s at home, leisure or the office. Reduced noise in the partitions and flooring of a structure leads to greater ease and a more efficient environment.
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. 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.
Does Your Development Need a Sound Insulation 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. It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
There are two ways in which to show compliance. You can either test to the regime set out in Approved Document E (ADE), or pay to use Robust Details. 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. 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. When on-site pre–completion building sound tests are taken, architects have more scope with their design and can increase the sound insulation performance of the construction.

Sound Insulation Test Time
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
Sound testing procedure is quite simple and our engineers are happy to explain this on site. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. The noise from the source room and received by the receiver room, and background noise is measured with a sound level meter. The background noise level is also measured. The higher the background noise then the higher the source noise will need to be set, since the resulting noise level in the receiver room needs to be 10dB higher than the background noise at all measured frequencies. 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 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. 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.
Sound Testing Equipment to Expect
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. We use a loudspeaker and noise generator that produces white or pink noise on one side of the partition, and measure with a sound level meter on both sides to calculate the sound insulation performance of the partition. We use a tapping machine, which drops metal hammers onto the floor to create impact noise. We then measure the amount of sound that passes through the partition with a sound level meter in the room under the tapping machine. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. The outcome of the test is written in a report and sent to the customer. This report helps Building Control sign off your building.
It’s important to undertake a sound test if you have this kind of building:
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.
A new building with not less than two rooms
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
The development that has been converted must conform to Building Regulations sound requirements.
Design that don’t have Robust Details factored in
The Robust Detail Scheme, set up in 2004 by Robust Details Ltd, architects create design details for walls and floors that were tested formerly for sound insulation and meet the sound performance parameters stated by Part E of 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. Minimum criterion differs based on the type and purpose of the development. A development with rooms intended as residences, like a hostel or hotel, won’t have the same criteria as a structure for permanent dwelling.
