Sound Insulation Testing
Sound Insulation Testing – Often referred to as Acoustic insulation or Acoustic Testing, is designed to ascertain how well insulated certain building elements in a property are. The amount of noise should be an acceptable level to neighbours in adjoining properties. This ensures a good quality of life for those living in both properties and the building will comply with Part E of the Building Regulations.
You will almost certainly have to get Sound Insulation Testing if:
- New developments being built that contain more than one dwelling/flat.
- Converting a building into flats.
- Building a property for use as a residential home, such as a hotel or nursing home.
- Buildings not built using Robust Details
What Needs to Be Provided to Complete a Sound Insulation Test?
- A complete set of architectural drawings (floor plans, sections, elevations and site plan).
There are a number of different times when you will have to have Sound Insulation Testing. The requirement for this will usually be specified by the local authority. If you are still unsure as to whether you need a Sound Insulation Test, please contact us and we will advise accordingly.
Sound Insulation Testing is a confusing topic for many, so we have created a comprehensive Q & A section for you. We want you to understand everything about the subject before you hire us to complete the job.
How Does Sound Insulation Testing Work?
UKBC carry out a Sound Insulation Tests in a couple of different ways. Both of these methods are effective at determining the level of sound insulation in a property:
- Airborne Sound Insulation Test – This involves using a loudspeaker and amplifier to create a number of different frequencies. The amount of decibels is recorded in the room containing the loudspeaker, as well as in an adjoining room. By doing this, the exact amount of noise transmitted to the next room through party walls can be measured.
- Impact Sound Transmission Test – This involves using a machine with five metal hammers on it. They’re used to bang on party floors. This mimicks the sound of footsteps. A sound level meter is then used to measure how much noise this creates in a neighbouring property.
What Conditions Does Sound Insulation Have to Meet?
A dwelling has to provide sufficient sound insulation to ensure that a reasonable standard of living can be met. In the case of some public or commercial buildings, sound insulation is required to ensure that certain areas remain quiet. This is the case in hospital wards and school classrooms.
Pubs and nightclubs must have sufficient sound insulation to ensure that the noise they produce does not overly disturb residents in the area. There are also times when sound insulation testing needs to be carried out when there are complaints from residents, although sufficient access will be needed.
What are Robust Details?
Robust Details are details that have been pre-approved for use in walls and floors. They are already proven to be effective at sound insulation. If these details are provided, this can be an alternative to having a Sound Insulation Test on the property.
Only new build properties can use Robust Details and there are a number of different conditions that have to be met in order to comply so please contact us for more details.
During a Sound Insulation Test, your UKBC technician will also test the reverberation time. This is the time it takes for a noise to disappear in the adjoining room. This is done using a simple sound level meter.
Dependent on the area you live in, we will have to perform different amounts of tests. In England and Wales, houses require two airborne sound insulation tests. In Northern Ireland there are different guidelines for the same type of property. We can advise you further on this subject when you call and speak to one of our advisors. Regardless of where you live, we will always ensure tests are thorough and that they completely meet the requirements laid out in the regulations.
Will Sound Insulation Testing be Disruptive to the Site?
Due to the nature of this test, it is necessary that surrounding areas are virtually silent. The test will take from 1-3 hours, so work will not be disrupted for long. We will also need doors and windows to already be fitted for this test to be carried out.
When Will I Receive the Results?
Preliminary test result will be issued before we leave your site. This will allow you to have the necessary documentation to prove compliance and move your project along as quickly as possible. We’ll then send certificates and a full report by email within 7 working days. We can also send printed copies if needed.
If a property fails a Sound Insulation Test we will provide assistance to remedy the problems. We’ll advise know how issues can be solved in the most cost effective way.
Building Control may ask for additional buildings on your development to be tested in order to ensure that the other buildings have been insulated to a sufficient standard. We are able to provide an initial assessment before the testing to give you an indication of what needs to be done to ensure that the test is a success.
Where possible, we recommend that you speak to us as early on in the build as you can. By doing this we can provide specific recommendations throughout the project to ensure that remedial action is not needed at the end.
If you are worried about achieving compliance we also offer a consultation service. This offers advice on materials and other factors at design stage, therefore giving you the best chance of getting a pass first time.
Is Credit Gained for Sound Insulation Testing?
Sound Insulation Testing can gain credits for a couple of different schemes, such as the Code for Sustainable Homes. BREEAM credits can also be earned through having Sound Insulation Testing on a property, in the categories Hea 05 and Pol 05. By hiring us early in the project we can advise on what needs to be done to ensure the different criteria are met for these schemes.
Why Use Us?
At UK Building Compliance we have been conducting Sound Insulation Testing for a number of years. We’ve built a solid reputation for completing the job in a professional and hassle-free manner. There are certain things that we can promise you when you hire us, such as:
- We will complete the task at hand thoroughly and honestly, never failing to omit even the smallest of detail.

Other Services to Consider
We also offer a number of other different services, some of which might be of use to you if you require air pressure testing. These services are:
- SAP Assessments – required by every new dwelling, in order to ensure that it satisfies requirements pertaining to environmental impact.
- SBEM Assessments – similar to SAP assessments, however they are for non-dwellings.
- Domestic EPCs – these must be issued to every new dwelling, or any dwelling about to be sold.
- Commercial EPCs – these must be issued to any commercial building upon completion or when it is being sold.
- Display Energy Certificates – these must be displayed in all public buildings, to show visitors how energy efficient the building is.
- Ventilation Testing – this ensures that a building's ventilation is efficient and effective.
- U Value Calculations – these show how much heat is lost through different materials used in the construction of a building.
