The measurement of the sound reduced by partitions in a development, such as a wall or floor, is known as sound insulation testing or sound testing. It assesses how good the soundproofing materials fixed to the property development are. 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. 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.
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 Sound Insulation Testing Does
To adhere to Building Regulations ADE requirements, adjoining walls, floors and ceilings in a building will have to be tested, except where licensed Robust Details were used. Sound testing measures the impact and airborne sound moving through new and old adjoining buildings. This tests include the boundary walls between buildings and in-between the spaces in a development.
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. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. A dwelling or development of normal size and simplicity will more than likely be tested in 90 minutes.
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.
You will get a detailed written report and sound test certificate about a day after, if possible. 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 ADE also states the categories of developments that should be tested. There are three: rooms, flats and houses (including bungalows) that are lived in. Examples are student accommodation, hotel rooms and care homes. The volume of testing carried out on each group is written below.
Why is Sound Insulation Testing Relevant?
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. ADE ensures that new building are resistant to noise from adjoining buildings and other rooms within the same building. Sound affects our life no matter where we are, at home, work or while relaxing. Places with lowered noise are more comfortable and enabling. Sound testing ensures that noise reduction in a building is effective.
Sound insulation and speech privacy are critical for a variety of reasons. Inadequate sound insulation can be extremely distressing to those affected by it. For instance, in an apartment building, the neighbour upstairs might invite friends over during the weekend and put on loud music. The inhabitant downstairs might spend night hours as work time. If the sound insulation is inefficient, this could lead to lots of problems. Sound insulation impacts people’s lives in various 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.
How Do I Know if I Need a Sound 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
ADE thoroughly explains sound testing and makes it compulsory.
To conform, you can either follow the procedure outlined in ADE or make use of Robust Details. Robust details are separating elements that have been pre-tested and conform to Approved Document E sound insulation standards. You also cannot expand or tweak the design from the Robust Detail Approved listing. However, you are exempt from the sound test. 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. 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.

Ideal Period for a Sound Insulation Test
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. During the test, you should provide the following:
- Access to all rooms. The only exception is if a schedule was created before the test time.
- 240V power supply
- A noiseless site
How is sound insulation testing carried out?
Sound insulation testing is not complicated. Our highly qualified engineers will be willing to explain it in detail on the site. The boundary floors and walls get airborne tests. Floors get an additional impact test.
The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. A sound level meter is then used to take noise measurements within the source room and the receiver room. Noise in the background is also calculated. More noise in the background means a higher level of source sound will be created since it’s supposed to be 10dB higher than background noise on all calculated 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.
This basic level difference is then ‘corrected’ to allow for the reverberation time (the time is taken, in seconds, for a noise source to decay by 60dB) and the existing levels of background noise monitored whilst in the receiving 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 done and the outcome is checked against ADE requirements for the type of building. This is a simple way of explaining how a sound test is conducted.
Sound Test Equipment Used
The testing equipment used are UKAS calibrated. Our highly qualified engineers test based on present Building Regulations conditions. An airborne test calculates the amount of sound moving through a separating element. Equipment used for the test include a noise generator, speakers and sound level meter. A sound level meter and a tapping machine which drops metal hammers is used for impact testing. Testing is done on rooms that can be lived in. E.g. lounges, kitchens, bedrooms and living rooms. 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:
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.
Two or more new build dwellings or flats
This makes sure that the sound insulation for the building meets all the necessary requirements.
Conversions of former single dwelling properties into flats
When turning the single dwelling into several flats or units, the sound performance requirements of Building Regulations must be met.
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. If the design does not completely follow Robust Details, sound insulation testing will occur to be certain the building meets ADE criteria. A building built as a permanent dwelling has different minimum standards from a building with rooms built for residential purpose, like a hotel or a hostel.

Airborne and impact ceilings/floor tests
The ceilings/floors of developments undergo impact and airborne floor testing. The calculation of the sound level transferred from one unit to another through a separating floor via impact is called an impact test. The adjoining floors/ceilings of rooms intended as residences usually have both impact and airborne sound tests.
Testing in line with Part E of Building Regulations
Our sound insulation tests meet the requirements of Building Regulations Part E, which describes building structures resistance to the movement of sound within and from adjoining structures. The minimum airborne sound insulation test result should be 45dB DnTw+Ctr while the maximum impact sound test result should be 62dB L’nTw for new structures. Converted properties get a slightly different requirement. Expected minimum airborne sound insulation test result is 43dB DnTw+Ctr while expected maximum impact sound test result is 64dB L’nTw.
Testing for sound insulation
We want to give our customers the most highest chance to acquire a pass and via our offer skilled services. A new dwelling may have to undergo an airborne and impact test to meet the benchmark of greater than 45dB DnTw+Ctr and less than 62dB L’nTw. We frequently give robust advice to project managers and developers from the start of the construction, ensuring that they’ll have adequate sound insulation to pass a sound test.

Sound resistance and performance: Document E of Building Regulations (England and Wales)
We have fully accredited engineers who can visit your property to issue appropriate certification that complies with the building control.
Building Standards Division (Scotland)
Section 5.1 of the Scottish Building Standards stipulates that “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 performed after construction, using the procedures given in annex 5.C. of the Scottish Standards. Standard 5.1 does not apply to: fully detached houses or roofs or walkways with access solely for maintenance, or solely for the use of the residents of the dwelling below.
How to get a pass certificate for your sound test
The best method to guarantee you pass your sound test is to design the building with a view to good sound insulation performance. This shouldn’t be exorbitant, and can save time and cost at the end, without your having to correct sound problem or pay for a re-test. We offer design services to enable separating walls and floors with good sound insulation to meet the requirements of ADE, 2003. 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 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 fixed are sealed Light switches, light fittingsand plug sockets are properly fitted Our accomplished acoustic consultants work with developers, planners, contractors, and architects of all sizes from the early stages of the building plan to help limit any potential sound insulation performance problems to the completion of the construction, guaranteeing that all properties meet the criteria of Building Regulations Document E 2003.
Investigation and report certificates
To get details of the results of a completed sound insulation test, we will provide you with an analysis and report certificate. 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 the results look like
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. In the event that some part of the building does not meet up with the conditions of Document E, remedial work and a retest is required. We give remedial design advice to help you achieve Building Regulations standards.
