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. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo 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. 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.

Our highly capable sound test engineers will be available on site when you need them. They will give you a verbal result of the test, once taken and a written report will be issued to you by the following working day.

What is a Sound Insulation 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 testing conducts impact and airborne sound test on structures. The tests include the separating floors, walls and areas between buildings within developments.

What is involved in a Sound Test

While producing lots of noise, sound test needs a quiet site to be conducted efficiently. Due to this fact, the workers in the site should not be present at the time of the test. Undertaking sound tests on site varies according to the size and complexity of the building project and the site conditions. Generally, a sound insulation test takes about 90 minutes for a simple, regular sized project.

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.

The entire report and individual sound test certificate will be sent to you the day after. The way a sound test is conducted is determined by ADE of Building Regulations. It mandates that in all developments, every 10 units in a group or sub-group will undertake one set of tests. It explicitly states what a sub-group is in Section 1. 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. The volume of testing carried out on each group is written below.

Why Sound Testing is Required

From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. 62dB L’nTw or less impact sound and 45dB DnTw+Ctr or higher airborne sound insulation is the required result. 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. 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 having privacy while speaking are crucial for a number of reasons. When sound insulation is deficient, it can cause discomfort to occupants. 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 impacts people’s lives in various ways. It can be useful in dwellings with neighbouring units/flats/rooms which have diverse purposes, by guaranteeing that an occupant in a room will hear as little noise as possible from the neighbouring room.

How to Know if You Need Sound Insulation Testing

You need sound insulation testing if you:

  • Build a new development of 2 or more dwellings / flats
  • Convert a former single dwelling into flats
  • Build a Nursing Home or rooms for residential use, i.e. hotel or hostel
  • Have designs which do not adhere to Robust Details

ADE thoroughly explains sound testing and makes it compulsory.

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. The Robust Details scheme means that testing is not necessary, but is strictly limited to the design given in the Robust Details approved list. Sound insulation testing is a more flexible approach. You can pick from a plethora of designs, as opposed to Robust Details. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.

Sound Insulation Test Time

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. 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 Done?

Our sound test engineers can answer your questions and make the sound test process easy to understand on site, during the time of the test. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.

A big or multidirectional speaker, with a generator of pink or white noise is used to the biggest room. A sound level meter calculates the noise in the source room and 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. When conducting airborne sound insulation tests, two speakers are placed in each source room. The noise level in the receiving room is measured to get the sound difference between the source and receiving room.

This difference is modified to include background noise in the receiver room and reverberation time – time whereby a sound fades away in a closed space by 60dB. Impact tests are done by placing a standardised tapping machine on the floor. The noise level is then recorded in the room below. Calculations are undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. 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.

What Sound Insulation Testing Equipment do we use?

Our accredited engineers are testing to the current standards. We use only UKAS calibrated equipment, as stated by the building regulations. Airborne sound test is the measurement of sound moving through the air through a wall or floor. A loudspeaker and noise generator is used in one room while a sound level meter is used in both rooms for measuring level of noise. 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. 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 testing measures the impact and airborne sound moving through new and old adjoining buildings. This could affect the separating walls between buildings or in-between the spaces in a development.

Two or more new build dwellings or flats

This ensures that a sound insulation system installed in residences meets the requirements of ADE.

Converting a property into several units

All the units that have been built are to be constructed in alignment with Part E of Building Regulations.

Designed in a way that does not adhere to Robust Details

Robust Details Ltd began the Robust Details scheme in 2004. The scheme enables architects use design details for separating elements, which have been tested before to comply with Document E standards. 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 during testing will depend on a variety of factors such as if the development is intended to be a permanent dwelling, or classified as “rooms of residential purposes” (e.g. hotels, student accommodation, etc).

Sound resistance and performance: Document E of Building Regulations (England and Wales)

Our certified engineers can come to your building whenever it might suit you to undertake sound insulation testing to Part E of Building Regulations adherence, recognised by Building Control.

Scotland Standard division for properties

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.” 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 Do I Pass a Sound Insulation 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. 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. Whether you want some initial tests on your project, or comprehensive reports at the end, we can help you at the level that you need. The following criteria should be followed to provide you with the best chance of passing your sound test: Inner and outer doors and windows have been installed and can be used Skirting boards are fitted Fix all light switches, light fittings and plug sockets. 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.

Certificates for test evaluation and report

To obtain a thorough evaluation of your building, we issue a report certificate within 24 working hours where possible. Our highly capable sound test engineers will give you a verbal result of the test, once the test is taken and proffer solutions to possible problems or future areas of concern. 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.

The results

You will get your sound insulation test certificate whether you pass or fail the sound tests. If a partition wall or floor does not comply with Part E standards, repair work and another sound test will be needed. We can give robust advice on that to ensure you pass.


Sound Insulation FAQ’s

The minimum requirements depend on a variety of factors such as if the development is a new build or refurbished, whether the development is intended to be a permanent dwelling, or classified as “rooms of residential purposes” (e.g. hotels, student accommodation, etc).

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. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound insulation of no less than 43dB DnTw+Ctr.

Flanking sound (or flanking noise) is sound that transmits between spaces indirectly, going over or around, rather than directly through the main separating element. This can allow sound to transmit between spaces even though the main separating element itself provides good acoustic insulation. Engaging our services at an early stage allows us to check designs and add necessary measures to prevent this occurring after construction. In the worst cases, flanking can exceed the direct transmission and lead to a failed test, despite highly specified partitions.

In the case of impact sound, the building construction is caused to vibrate as a result of a physical impact, such as footsteps on floors or stairs. The resulting vibration is radiated into other rooms in the building.

We can provide preliminary results on the day of test. We strive to deliver next day reporting in all scenarios regardless the complexity or size of the project. The delivered report will be comprehensive and detailed, to ensure all relevant issues are covered. The best recommendations can also be sent in a separate report or email.

We can normally conduct up to a maximum of three sets of tests per day. One set is two airborne floor tests, two airborne wall tests and two impact floor sound tests.

When it comes to the acoustic tests, a full set of tests should take approximately 90 minutes.

The requirements of sound insulation testing are fully detailed in the Building Regulations Approved Document, available here [link], under Part E (2003).

This requires all residential buildings to be tested when they involve walls and/or floors. These are known as party elements.

Assuming no tests are failed, building control bodies should stipulate at least one set of tests for every ten dwelling-houses, flats or rooms for residential purposes in a group or sub-group.

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. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound insulation of no less than 43dB DnTw+Ctr.

We recommend that if possible, we are contacted before a build to provide a design review and advice on how to meet quality standards.

Should the test fail, we can offer advice on how to improve the sound insulation. We have consulted on hundreds of building projects in the past, and have ensured all of them have met the building regulations. If a sound insulation test fails, we can give remindial advice to ensure the tests passes later.

We understand that most clients would prefer testing to take place as soon as possible. Once you get in touch we will schedule the test at the earliest available opportunity.

You can call us today to set up an appointment for sound insulation testing. Our scheduling is flexible so that you can get the service you need at your convenience.

Ideally, a test should be carried out as early as possible as problems are more difficult to fix the further along you are. Where possible, it’s recommended that testing is carried out before kitchens or bathrooms are installed. The minimum that we require to be able to carry out a test is:

  • All doors, windows and seals should be fully fitted and closable
  • All electrical fittings should be fitted and working
  • 240V mains power must be available on-site in all rooms
  • Gaps in walls and floors should be fully sealed
  • All walls and ceilings should be plastered
  • There should be no holes remaining in floors or ceilings
  • Testers will require access to all rooms on all levels

Pre-completion sound testing is a building regulation requirement for all purpose built & “formed by material change of use” (i.e. refurbished) properties since 2003. Sound testing is undertaken in a percentage of properties in each development to ensure that the separating walls & floors between habitable rooms of neighbouring properties meet the minimum requirements as defined by Approved Document E, commonly referred to as ADE.

From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. New builds must achieve impact sound test results of no more than 62dB L’nTw and airborne sound loss of no less than 45dB DnTw+Ctr. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound loss of no less than 43dB DnTw+Ctr. Approved Document E sets out details pertaining to the resistance to the passage of sound.

This Approved Document, as part of UK Building Regulations helps to ensure that newly built or converted houses and residencies, flats and residential spaces and other relevant buildings are constructed to minimum standards that provide ‘reasonable resistance to sound from other parts of the same building and from adjacent buildings.’ All of our tests are fully compliant with Approved Document E and our expert team have been carrying out compliant tests for many years, for thousands of satisfied customers throughout the UK.

We understand the sectors our clients work in. Our advice is not only technically robust but also practical and helpful to our client’s particular situation. At AF Acoustics, we always look at the bigger picture and work towards the ultimate development goal.

Airborne sound (or airborne noise) is sound that is transmitted through the air. Airborne Sound Insulation is the insulation against noise originating in air, e.g. voices, music, motor traffic, wind. The greater the airborne sound insulation between two rooms, the lower the resulting sound level in the receiving room.

This is unlike Impact Sound Insulation that protects against noise originating directly on a structure by blows or vibration e.g. footsteps above, furniture being moved, drilling and hammering the structure.
