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 is compulsory for new buildings and refurbishment projects, according to Approved Document E (ADE) updated in 2003.
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. 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 pride ourselves on the facts that our sound insulation certificates are issued with speed and 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 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 conducts impact and airborne sound test on structures. The tests include the separating floors, walls and areas between buildings within developments.
What is part of 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.
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 complete report and sound insulation test certificate can be produced and issued 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 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. Find below the testing stipulation for each kind of development.
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. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw. 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. When sound resistance is high in party walls and floors, the environment is more comfortable, since sound affects every aspect of our lives – work environment, home environment and while relaxing. This is why sound testing is crucial.
There are so many more reasons why sound insulation and speech privacy are vital. An inefficient sound insulation treatment will lead to uneasiness for the inhabitants of the dwelling. 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 helps improve the quality of a person’s life in diverse 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.
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. It is imperative that sound insulation tests be undertaken, as explained and stipulated by ADE.
All you have to do is follow the guidelines listed in the document or pay to use Robust Details and you will have fulfilled the requirements. Robust details are separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. 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. 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.

When Should the Sound Tests be done?
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?
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. The separating walls undergo airborne tests while separating walls and floor undergo airborne and impact tests.
A pink or white noise generator and a large speaker is used for the test in the biggest room between the two undergoing testing. The sound generated and received 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.
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. 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. Of course, this is a simple way of describing the procedure followed when a sound test is carried out, but it enables you to understand it better.
Sound Test Equipment Used
Our accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the building regulations. An airborne sound test measures levels of sound transmitted through the air through a separating element. 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. 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. 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.
Redevelopment of a building with a single dwelling into 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
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. 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.

Scotland Standard division for properties
According to Section 5.1 of the Scottish Building Standards, “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 pass a 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. If you are unsure of how to build the separating floor and wall constructions and associated junctions across your development to satisfy the requirements of Document E 2003, we can offer design advice. 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 conditions will provide you with an ample chance of passing the sound test: Windows and internal and external doors are fitted and operable Fit and seal skirting boards Plug sockets, light switches and fittings are in place and working. 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.
