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. New structures and reconstructed developments have been mandated by the Building Regulations to test for sound upon completion, since Approved Document E (ADE) was reappraised 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.
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 is a Sound Test?
Developments must test all walls, floors and ceilings that separate buildings or neighbours in a dwelling, to conform to Approved Document E (ADE) of the Building Regulations. You may not have to test your building if you used Robust Details which were approved before their installation. 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 Sound Insulation Testing
A sound insulation test creates a high amount of noise but needs a site with low noise levels to be taken effectively. As a result of this, workers in a testing area might have to leave the development temporarily, so that the test can be free from errors. 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. The extent of testing required for these three groups is shown below.
Why Sound Testing is Required
From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. The impact sound test result should not be more than 62dB L’nTw and the airborne sound insulation should not be less than 45dB DnTw+Ctr. 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 speech privacy are important because not having them results in an unfavourable environment for those living in the development. For instance, an inhabitant in an apartment building sleeps during the day and works at night all the days of the week. If the neighbour in the upstairs flat has friends over and plays loud music, without a good sound insulation system, the working occupant will be uncomfortable and uneasy. Sound insulation helps improve the quality of a person’s life in diverse ways. Then there are developments where each neighbouring room / flat / unit has mixed uses. If the development has passed the sound insulation test, noise is reduced to a minimum.
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
Document E of the Building Regulations explains sound insulation testing and makes it a necessity.
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 design details for walls that were tested formerly and meet the sound performance parameters stated by Part E of Building Regulations. The Robust Details scheme means that testing is not necessary, but is strictly limited to the design given in the Robust Details approved list. This becomes difficult when you need to pick a more appropriate or cost-effective design that will suit your needs. Sound tests enable you do that, making it more flexible. Sound insulation testing can also help architects enhance their building design and in turn the sound insulation of the building.

When Should the Sound Tests be done?
Ideally, we would conduct a test when a development nears completion, and once all internal and external doors and windows have been fitted. We can test earlier to check if there are any problems. 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 carried out?
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. We carry out airborne and impact tests on separating floors, and airborne tests on separating walls.
The source sound is produced with a white or pink noise generator with a dodecahedron speaker in the largest room. The sound in the source room and receiver room (sharing a separating wall with the source room) 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. 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 conducted by fixing a tapping machine on the floor. Noise level in the room below is measured at various different frequencies. Calculations are done and the outcome is checked against ADE requirements for the type of 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.
Kind of Testing Equipments Used
Our licensed engineers use UKAS calibrated equipment to measure sound insulation according to the present standards of Building Regulations. An airborne sound test measures levels of sound transmitted through the air through a separating element. 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 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. Sound insulation tests are conducted in liveable rooms like the sitting room, lounges, kitchen/living spaces and bedrooms. You will get the test results in a report within a working day. This report can be used to help sign off your building as it is accepted by Building Control.
These kinds of properties should undergo a sound insulation test:
Sound Insulation Testing checks for both airborne and impact noise travelling through new or existing buildings. This may affect party walls and floors between new and existing buildings, or between spaces within a new development.
Two or more new build dwellings or flats
This is to ensure that the sound proofing of the building is up to standard for residential purposes.
Converting a property into several units
The transformation of a single dwelling property into flats must adhere to the sound insulation standards of Building Regulations.
Designed in a way that does not adhere to Robust Details
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 does not strictly adhere to Robust Details, a sound insulation test becomes necessary to meet Building Regulations. The minimum criterion is based on various factors such as the purpose of the development and if it is a permanent dwelling or rooms to be used as residences like students’ accommodations and hotels.

The adjoining floors/ceilings of rooms intended as residences usually have both impact and airborne sound 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 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.
