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. 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.
Building Control does not issue completion certificates to buildings that don’t have a sound insulation certificate. Contractors and developers have sometimes discovered this, to their detriment. 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. When the tests are completed, we work quickly to issue your certificates; we take great pride in our efficiency.
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 Insulation Testing Does
Walls and floors that separate dwellings in a building are expected to be sound tested, as mandated by Document E of Building Regulations. Only dwellings that have used Robust Details, which licensed before the installation, are exempted from the test. 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?
Even though sound insulation testing equipment produces lots of noise, sound testing requires quiet conditions and dwellings. Because of this, workers on the site would have to leave during the time of the test, to avoid errors in the test calculation. Sound insulation testing varies by size, complexity and conditions of site 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 report and individual sound test certificates can be generated and sent out the next day. 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 Buildings to be tested are categorised into three kinds: houses, flats and rooms like care homes, student accommodation and hotel rooms. How much testing that is required for each category can be found below.
Why is Sound Insulation Testing Required? Why is it Important?
After the 2003, Approved Document E mandates that all new structures in UK must take a sound insulation test before completion. Results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. 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. 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. For instance, in an apartment building, the neighbour upstairs might invite friends over during the weekend and put on loud music. The inhabitant downstairs might spend night hours as work time. If the sound insulation is inefficient, this could lead to lots of problems. This is just one instance of the influence of sound insulation on our lives. Then there are developments where each neighbouring room / flat / unit has mixed uses. If the development has passed the sound insulation test, noise is reduced to a minimum.
How Do I Know if I Need a Sound 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
ADE thoroughly explains sound testing and makes it compulsory.
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. 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
A sound test is usually conducted just before the construction is completed, and when all the doors and windows have been fixed. However, we can test your building earlier to check for problems. 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.
The Process of a Sound Test
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
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 calculates the noise in the source room and receiver room. Background sound is also calculated. Noise in the receiver room should be 10dB more than the background noise at all frequency measurements, so source noise is set to be greater than background noise. For airborne sound tests, two individual speaker positions are used for each source room. Measurements are then made to determine the levels in the receiving room of the tested partition in question. This gives a basic level difference between source and receiver rooms.
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. A tapping machine is placed on the floor to execute an impact sound insulation test. The sound level in the room below it is recorded. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.
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. An airborne test is used to check how much sound is moving through the air between partitions. 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. For impact test, a tapping machine that makes impact sound by dropping metal hammers is used. A sound level meter is used to measure in the receiving room below the room the tapping machine is in. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. 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.
These kinds of properties should undergo a sound insulation test:
The airborne and impact sound going through new and old buildings are evaluated by sound testing. This can impact adjoining walls and floors between the building.
A new building with 2 or more dwellings
This makes sure that the sound insulation for the building meets all the necessary requirements.
Conversions of former single dwelling properties into flats
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Designed in a way that does not adhere to Robust Details
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 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.

Part E of building regulations resistance to the passage of sound (England and Wales)
We have fully accredited engineers who can visit your property to issue appropriate certification that complies with the building control.
Standard division for structures (Scotland)
Section 5.1 of the Scottish Building Standards 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.” The following are exempt from the testing techniques given in annex 5.C. of the Scottish Standard and Standard 5.1 – completely segregated rooftops, houses or walkways whose access is only used for upkeep or for the utilization of the inhabitants of the dwelling beneath.
How to get a pass certificate for your sound test
The most effective way to ensure you pass your sound test is to plan the project with sound insulation in mind. This does not need to be costly, and can save considerable time and expense at the end of the project, not to mention avoiding escalating remedial and re-test costs. We offer design services to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. Whether you want some initial tests on your project, or comprehensive reports at the end, we can help you at the level that you need. The following criteria should be followed to provide you with the best chance of passing your sound test: Inner and outer doors and windows have been installed and can be used Skirting boards are fitted and sealed Fix all light switches, light fittings and plug sockets. Our expert acoustic consultants work with planners, developers, architects and contractors from the beginning of the design stage till when the property is finished to ensure it meets the conditions of Document E 2003.
Test report certificates
To get details of the results of a completed sound insulation test, we will provide you with an analysis and report certificate. 6. Even before you get the certificate, you get the verbal results of the test. First, our completely skilled and competent sound insulation test engineers give you a verbal result at the site. They also offer advice on potential problems. Then the test report certificate is sent to you within 24 working hours, when feasible.
Your test certificate will show if your development passed or failed the test and show if it adheres to the requirements of Part E of Building Regulations. If parts or all the building fails the test, repair work and a retest is recommended. We provide design advice to ensure your property does proper remedial and meets up with the necessary requirements.
Sound Insulation FAQ’s
What are the minimum requirements for separating party walls and party floors between neighbouring dwellings?
The minimum requirements depend on a variety of factors such as if the development is a new build or refurbished, whether the development is intended to be a permanent dwelling, or classified as “rooms of residential purposes” (e.g. hotels, student accommodation, etc).
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. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound insulation of no less than 43dB DnTw+Ctr.
Flanking sound (or flanking noise) is sound that transmits between spaces indirectly, going over or around, rather than directly through the main separating element. This can allow sound to transmit between spaces even though the main separating element itself provides good acoustic insulation. Engaging our services at an early stage allows us to check designs and add necessary measures to prevent this occurring after construction. In the worst cases, flanking can exceed the direct transmission and lead to a failed test, despite highly specified partitions.
In the case of impact sound, the building construction is caused to vibrate as a result of a physical impact, such as footsteps on floors or stairs. The resulting vibration is radiated into other rooms in the building.
We can provide preliminary results on the day of test. We strive to deliver next day reporting in all scenarios regardless the complexity or size of the project. The delivered report will be comprehensive and detailed, to ensure all relevant issues are covered. The best recommendations can also be sent in a separate report or email.
We can normally conduct up to a maximum of three sets of tests per day. One set is two airborne floor tests, two airborne wall tests and two impact floor sound tests.
When it comes to the acoustic tests, a full set of tests should take approximately 90 minutes.
The requirements of sound insulation testing are fully detailed in the Building Regulations Approved Document, available here [link], under Part E (2003).
This requires all residential buildings to be tested when they involve walls and/or floors. These are known as party elements.
Assuming no tests are failed, building control bodies should stipulate at least one set of tests for every ten dwelling-houses, flats or rooms for residential purposes in a group or sub-group.
We recommend that if possible, we are contacted before a build to provide a design review and advice on how to meet quality standards.
Should the test fail, we can offer advice on how to improve the sound insulation. We have consulted on hundreds of building projects in the past, and have ensured all of them have met the building regulations. If a sound insulation test fails, we can give remindial advice to ensure the tests passes later.
We understand that most clients would prefer testing to take place as soon as possible. Once you get in touch we will schedule the test at the earliest available opportunity.
You can call us today to set up an appointment for sound insulation testing. Our scheduling is flexible so that you can get the service you need at your convenience.
Ideally, a test should be carried out as early as possible as problems are more difficult to fix the further along you are. Where possible, it’s recommended that testing is carried out before kitchens or bathrooms are installed. The minimum that we require to be able to carry out a test is:
- All doors, windows and seals should be fully fitted and closable
- All electrical fittings should be fitted and working
- 240V mains power must be available on-site in all rooms
- Gaps in walls and floors should be fully sealed
- All walls and ceilings should be plastered
- There should be no holes remaining in floors or ceilings
- Testers will require access to all rooms on all levels
Pre-completion sound testing is a building regulation requirement for all purpose built & “formed by material change of use” (i.e. refurbished) properties since 2003. Sound testing is undertaken in a percentage of properties in each development to ensure that the separating walls & floors between habitable rooms of neighbouring properties meet the minimum requirements as defined by Approved Document E, commonly referred to as ADE.
From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. New builds must achieve impact sound test results of no more than 62dB L’nTw and airborne sound loss of no less than 45dB DnTw+Ctr. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound loss of no less than 43dB DnTw+Ctr. Approved Document E sets out details pertaining to the resistance to the passage of sound.
This Approved Document, as part of UK Building Regulations helps to ensure that newly built or converted houses and residencies, flats and residential spaces and other relevant buildings are constructed to minimum standards that provide ‘reasonable resistance to sound from other parts of the same building and from adjacent buildings.’ All of our tests are fully compliant with Approved Document E and our expert team have been carrying out compliant tests for many years, for thousands of satisfied customers throughout the UK.

Airborne sound (or airborne noise) is sound that is transmitted through the air. Airborne Sound Insulation is the insulation against noise originating in air, e.g. voices, music, motor traffic, wind. The greater the airborne sound insulation between two rooms, the lower the resulting sound level in the receiving room.
This is unlike Impact Sound Insulation that protects against noise originating directly on a structure by blows or vibration e.g. footsteps above, furniture being moved, drilling and hammering the structure.
