Sound insulation testing is used to measure the resistance of sound provided by an element of a building (such as a floor or wall) between dwellings. It essentially measures the effectiveness of the sound proofing treatment installed as part of a build or property development. Part E of Building Regulations requires sound insulation in buildings and mandates that all newly completed constructions and rehabilitated developments go through sound testing.
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. 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. We take great pride in providing our certificates to you as soon as possible after the tests.
AF Acoustics’ competent and well-trained engineers, who will be available for testing, can even let you know the verbal results of your sound test. You will receive a written report in the space of a working day.

What is a Sound Test?
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 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. The way a sound test is administered depends on the size and type of building and the development’s condition. Most of the time the test will be conducted in 90 minutes, for a simple, regular sized construction.
Once this is done, the sound test engineers give temporary results while they’re still on the site. They will also provide suggested solutions to possible problem areas noted during testing.
A full report and individual sound test certificates can be generated and sent out the next day. The sound testing regime is set out in the Approved Document E of the Building Regulations. It states that one set of tests is required for every 10 units in a group or sub-group. Sub-groups are defined in Section 1 of Approved Document E (ADE). Buildings to be tested are categorised into three kinds: houses, flats and rooms like care homes, student accommodation and hotel rooms. Find below the testing stipulation for each kind of development.
Importance of Sound Insulation Testing
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. 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. 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.
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. Sound insulation helps improve the quality of a person’s life in diverse ways. Sound insulation is also effective in buildings that have flats with mixed uses. If the building passed the sound test, you can be sure that noise reduction will be effective.
Do I Need a Sound Insulation 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
Building Regulations Part E discusses sound testing in detail and has made it a requirement.
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 separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. The Robust Details scheme means that testing is not necessary, but is strictly limited to the design given in 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. 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.

When can I carry out the sound insulation tests?
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 is Sound Insulation Testing Done?
The method of taking the test is not complex and our sound test engineers can explain it thoroughly on site, if you wish. Airborne tests are conducted on party walls while impact and airborne tests are conducted on party floors.
A big or multidirectional speaker, with a generator of pink or white noise is used to the biggest room. A sound level meter is then used to take noise measurements within the source room and the receiver room. The meter is also used to measure the background sound, to ensure that it’s 10dB lower than the source sound, as is the standard. More background sound leads to creating a higher source sound. Airborne sound testing is done in a similar way. First, two speaker positions are used for each source room. Then, the level of sound in the receiver room is measured so that the difference in noise level between the two rooms can be calculated.
The sound difference is adjusted to make an allowance for reverberation time (time in which the sound decays by 60dB) and background noise in the receiver room. Impact tests are carried out by means of a tapping machine placed on the floor to be measured. 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. This is of course, a somewhat simplified explanation without the various mathematical formulae involved, but helps to explain the process.
Type of Sound Insulation Test Machines We Will be using
You can expect UKAS calibrated equipment from us, as stipulated by Building Regulations. Our certified engineers conduct tests to meet the current guidelines. 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. For impact sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. Testing can only be completed on ‘habitable’ rooms. Habitable rooms can be bedrooms, lounges, living rooms and open plan kitchen/ living spaces. The outcome of the test is written in a report and sent to the customer. This report helps Building Control sign off your building.
A sound test is mandatory for these buildings:
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.
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 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. If the building design is not in line with any Robust Details, it will require sound testing to ensure its compliance with the buildings regulations. The minimum requirements are dependent on the kind of dwelling. Permanent dwellings and rooms for residential use have different requirements.

Impact and airborne tests for floors
These are taken on separating floors/ceilings between residences. An impact test measures the levels of noise transmitted directly through a separating construction. These floors in habitable rooms of flats undergo both impact and airborne tests.
Document E test
AF Acoustics sound testing adheres to ADE which stipulates information bearing on the sound resistance and performance of a property. The impact sound test of new dwellings should be 62dB L’nTw or less and airborne sound insulation 45dB DnTw+Ctr or more while impact results for reconstructed properties should be 64dB L’nTw and airborne sound insulation 43dB DnTw+Ctr or more.
With our professional and highly skilled expertise, we are willing to work with our clients to help them get a pass certificate in every situation.

Scotland Standard division for completed constructions
In the words of 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.” Fully detached roofs or walkways that are not used for residential purposes do not have to take the sound tests of the Scottish Standards 5.1.
How to get a pass certificate for your sound test
The most efficient way to make sure you pass sound insulation test is to have a plan that puts sound insulation into consideration from the begining. You don’t have to spend too much for this and it will save you money in the long run, ensuring you don’t pay remedial or 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. The degree of guidance you require can vary, from site visits and comprehensive design reports, to simpler initial testing to know the starting point for construction. The following will give you a better chance of passing the sound test: Install and make sure that all external and internal doors and windows are operational Skirting boards are fixed are sealed Fix all light switches, light fittings and plug sockets. Our experienced acoustic consultants work with developers, contractors, architects and planners of all sizes from the early design stage to help minimise any potential issues right through to project completion, ensuring that all properties are compliant with Building Regulations Document E 2003.
