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.
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. Because we understand how the sound insulation certificate affects your building project, we ensure that you get it as quickly as possible after the test. 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.

How Sound Testing Works
To completely fulfil Building Regulations Part E requirements, the separating walls and floors of dwellings will be tested, unless approved Robust Details are used. The airborne and impact sound going through new and old structures are evaluated by sound testing. This can impact adjoining walls and floors between the structures.
What is involved in a Sound 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. 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 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 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 There are three types of grouping criteria that need to be assessed: dwelling houses (including bungalows), flats and rooms for residential purposes, such as student accommodation and hotel rooms, care homes etc. How much testing that should be done on each group is listed below:
Why is Sound Insulation Testing Relevant?
Before completing a building, all new constructions should be tested for sound insulation, as stipulated by Approved Document E since 2003. 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. 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 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 example of how sound insulation can affect the quality of life of people in different ways. 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.
Do You 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. Sound insulation is covered and made mandatory under Approved Document E of The Building Regulations.
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 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. Using Robust Details, without taking a test, limits you to the design you’ve picked. Sound testing provides more flexibility by allowing different designs and is often therefore more cost effective in many ways compared to the Robust Details Scheme. 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.

If you get a better price from another company, let us know and we will try to beat it.
Period Sound Insulation Test Should be Carried Out
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. 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.
How a Sound Test is Done
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. The boundary floors and walls get airborne tests. Floors get an additional impact test.
A pink or white noise generator and a large speaker is used for the test in the biggest room between the two undergoing testing. A sound level meter is then used to take noise measurements within the source room and the receiver room. 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.
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 sound tests are performed with a tapping machine positioned on the floor of the source room. Noise level in the room below is measured at various different frequencies. Calculations are done and the outcome is checked against ADE requirements for the type of building. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
Kind of Testing Equipments Used
The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. An airborne test is used to check how much sound is moving through the air between partitions. 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. 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. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. Test findings are fed into a report that will be sent to the client. This report will always be acceptable to Building Control and will help you to get your development signed off.
Sound insulation testing is essential for these dwelling types:
Sound insulation tests examine airborne and impact sound moving through buildings. It is usually undertaken between party walls and floors between buildings or between spaces within a new development.
Property with two or more units
This makes sure that the sound insulation for the building meets all the necessary requirements.
Converting a single development to flats
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Using designs where Robust Details are not included
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. Once the design does not strictly abide by the design from Robust Detail approved list, the structure will have to undergo a sound test to ensure it conforms to Building Regulations. The minimum requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.

Impact and airborne floor test
These are only carried out on separating floor/ceiling between dwellings. An impact test examines the level of noise moving from one dwelling to another through impact on adjoining floors/ceilings. The adjoining floors/ceilings of rooms intended as residences usually have both impact and airborne sound tests.
Our sound insulation testing in accordance with Building Regulations Approved Document E, which sets out details pertaining to the resistance to the passage of sound. For new buildings, results for impact sound should be 62dB L’nTw or less while those for airborne sound insulation should be 45dB DnTw+Ctr or more. Converted structures expected impact sound results increases by 2dB L’nTw while the airborne sound results reduces by 2dB DnTw+Ctr.

Part E of building regulations resistance to the passage of sound (England and Wales)
Our expert engineers can issue certificates for the sound insulation testing. They can visit the site and conduct the test that will lead to getting a certificate which is in line with Building Regulations and Building Control requirements.
Scotland Standard division for properties
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
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. 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. Our consultation process is led by your project requirements and may include assessment of design reports, test of the development and multiple site visits. The following conditions will provide you with an ample chance of passing the sound test: All windows and doors have been fitted and work Skirting boards are fitted and sealed Plug sockets, light switches and fittings are in place and working. Our professional acoustic professionals work with contractors, architects, developers, and planner from the beginning of the design to make sure that all requirements are met.
Certificates for test evaluation and report
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.
What do the results look like?
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. We can provide professional advice on designs that will surpass Document E standards if the building fails the test.
