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.
At the completion of the test, a sound insulation certificate is issued. Without the certificate, Building Control will not release the building completion certificate to the contractors and developers of the project. As a result of this, we try to ensure that you are issued with a sound insulation certificate as fast as possible. In fact, we are proud of our turnaround times and our team will issue your certificates as quickly as we possibly can.
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 is a Sound 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 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
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. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.
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.
A full and thorough report with the certificate of the test will be given to you within 24 working hours. The sound testing guidelines are stipulated in Building Regulations ADE. It requires one set of test to be conducted on 10 units in a group or sub-group. You can find out what is meant by a sub-group in Section 1 of 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 is required for each category can be found below.
Importance of Sound Insulation Testing
From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. This is to be certain that all new developments meet a uniform minimum criterion for resistance to sound from other parts of the development and adjoining developments. Sound insulation testing is important because sound affects the way we live, whether at work, in the home or whilst at leisure. Noise reduction between walls and floors could result in a more comfortable, productive environment.
Sound insulation and speech privacy are critical for a variety of reasons. Inadequate sound insulation can be extremely distressing to those affected by it. 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 instance of the influence of sound insulation on our lives. In a structure with flats for mixed purposes, a sound insulation test will make sure that there is maximum sound resistance from party walls and floors and less noise.
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.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. 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. When you use it, you don’t have to take a sound insulation test. However, you must abide strictly by the design from the Robust Details approved list. This becomes difficult when you need to pick a more appropriate or cost-effective design that will suit your needs. Sound tests enable you do that, making it more flexible. On-site pre-completion sound insulation testing gives architects more insight and ability to make their design lead to constructions that have a higher sound performance.

Period Sound Insulation Test Should be Carried Out
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 be able to conduct sound insulation testing we require the provision of a 240V power supply, and a quiet site (a noisy site can make conducting the tests extremely difficult). Access will be required to all rooms of the development unless a test schedule is determined in advance.
The Procedures of a Sound Insulation Test
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.
The test uses a dodecahedron speaker and pink or white noise generator for source sound. The sound source is placed in the largest room of the two. The noise from the source room and received by the receiver room, and background noise is measured with a sound level meter. Background noise is measured to make certain that the source noise is greater. This way the standard of the receiver room having a 10dB higher noise level at all calculated frequencies can be realised. 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.
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. 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. Calculations are done and the outcome is checked against ADE requirements for the type of building. Without the mathematical formulae used in the calculations, this is a simple explanation, however, it helps explain the testing process.
Type of Sound Insulation Test Machines We Will be using
The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. An airborne sound test measures levels of sound transmitted through the air through a separating element. 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 administered in room with residential purposes. For example, kitchens/living spaces, lounges, bedrooms and living rooms. 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 structure with 2 or more units/flats
This makes certain that the dwellings have adequate sound proofing.
Converting a property into several units
When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.
Designed in a way that does not adhere to Robust Details
Robust Detail Ltd set up the Robust Detail Scheme in 2004 to make sure architect and building designs construct partition walls and floors that comply with Approved Document E sound insulation standards. If the design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. The minimum requirements during testing will depend on a variety of factors such as if the development is intended to be a permanent dwelling, or classified as “rooms of residential purposes” (e.g. hotels, student accommodation, etc).

PART E Testing
Document E of Building Regulations requires certain criteria for the sound performance of a dwelling. Our sound insulation tests are conducted in accordance to these criteria. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result for newly completed constructions. On the other hand, 64dB L’nTw or less impact sound and 43dB DnTw+Ctr or higher airborne sound insulation is expected from refurbished buildings.

Resistance to the passage of sound: Approved Document E (England and Wales)
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.
Scotland Standard division for completed constructions
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.” Tests, which are conducted after building utilizing the methodology given in annex 5.C. of the Scottish Standard 5.1 does not apply to: completely disconnected houses, rooftops and walkways with access exclusively for the use of the occupants of the home underneath.
How Do I Pass a Sound Insulation Test?
Make sure you pass your sound test by having efficient sound insulation included in the building design. It saves time and money and helps you avoid repair work and re-test expenses. We offer design services to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. Our consultation may include several site visits and thorough design reports, or more basic initial tests on your structure. The are required in order to have good conditions to undertake the sound insulation tests: All windows and doors have been fitted and work Skirting boards are fitted Fix all light switches, light fittings and plug sockets. We work with several professionals in construction from the beginning of the design stage to the completion of the development to make certain it conforms to Document E 2003 of Building Regulations.
Test and report certificates
After the sound insulation test, the sound testing engineer will provide provisional results whilst on-site, as well as providing basic feedback about what has been noted during the test, e.g. potential problems or any future areas of concern. A full report and individual sound test certificates can be generated and sent out usually the next working day. 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.
A sound insulation certificate will be issued whether the Sound Testing results and report indicate compliance with Part E of the Building Regulations or not. If a partition wall or floor does not comply with Part E standards, repair work and another sound test will be needed. We can give robust advice on that to ensure you pass.
