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. The Building Regulations Approved Document E (ADE) states all new dwellings and renovated constructions should undergo sound testing.
Not having a sound insulation certificate issued after a test, has resulted in additional costs and expenses for developers. Any development that has not taken a sound test will not be given a completion certificate by Building Control. The significance of a sound insulation certificate cannot be overrated. Therefore, we ensure that you get the certificate speedily. We pride ourselves on the facts that our sound insulation certificates are issued with speed and efficiency.
Our highly qualified site engineers can arrive on site when needed. They will provide verbal results after the test and a written report will be sent to you within 24 working hours.

What Sound Testing Does
In order to comply with Part E of the Building Regulations, developments will require the testing of separating walls and floors. The only exception is where Robust Details have been used. Sound testing conducts impact and airborne sound test on structures. The tests include the separating floors, walls and areas between buildings within developments.
The Procedures Involved in a Sound Insulation Test
Even though sound insulation testing equipment produces lots of noise, sound testing requires quiet conditions and dwellings. Because of this, workers on the site would have to leave during the time of the test, to avoid errors in the test calculation. A sound insulation test on a project is taken according to the scale and complexity of the construction and the conditions of the site. 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 and thorough report with the certificate of the test will be given to you within 24 working hours. 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 Should Your Dwelling Undergo Sound Testing
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. 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. Sound testing is essential due to the fact that sound impacts us wherever we are, whether it’s at home, leisure or the office. Reduced noise in the partitions and flooring of a structure leads to greater ease and a more efficient environment.
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. For example, in a block of flats, your upstairs neighbour may (and not unreasonably) like to have friends over at the weekend, resulting in the playing of loud music. However, the downstairs occupant may be working nights and sleeping throughout the day, thus any inadequate sound insulation between these two flats would cause great disturbance and distress to the downstairs occupant. This is one way sound insulation can affect how a person lives. 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.
How Do I Know if I Need a Sound Test?
Are you converting your property into several units? Does your design not use Robust Details? Are you constructing a new building with more than two rooms? Are you building a nursing home or rooms that will used for residential purposes, like hotels and hostels? If so, your structure needs to undergo a sound test. 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 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. When you use it, you don’t have to take a sound insulation test. However, you must abide strictly by the design from 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. 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.
Cost of Sound Testing
We can send quotation that’s completely free of charge and is based on the kind of development you have. We have handled all kinds of sound insulation projects in UK and issue a report and certificate as quickly as possible. Our prices are affordable too and can beat others.
Sound Insulation Test Time
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. To be able to conduct sound insulation testing we require the provision of a 240V power supply, and a quiet site (a noisy site can make conducting the tests extremely difficult). Access will be required to all rooms of the development unless a test schedule is determined in advance.
The Process of a Sound Test
The procedures of a sound insulation test are not difficult. Our site engineers can help you understand it better during the testing time. For partition walls, airborne tests are carried out. For floors there are two types, airborne and impact tests.
The test uses a dodecahedron speaker and pink or white noise generator for source sound. The sound source is placed in the largest room of the two. A sound level meter is then used to take noise measurements within the source room and the receiver room. Background noise is measured to make certain that the source noise is greater. This way the standard of the receiver room having a 10dB higher noise level at all calculated frequencies can be realised. For airborne sound tests, two individual speaker positions are used for each source room. Measurements are then made to determine the levels in the receiving room of the tested partition in question. This gives a basic level difference between source and receiver rooms.
Finally, the difference in noise level is modified to accommodate reverberation time and background noise that was already in the receiver room. Reverberation time is how long it takes sound to decay 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 undertaken, and results achieved. The results are crosschecked to ensure they meet Document E of Building Regulations target. Without the mathematical formulae, this explanation highlights sound insulation testing procedures in a simple manner.
Type of Sound Insulation Test Machines We Will be using
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 sound testing, the equipment used is a tapping machine that uses dropping hammers to create noise and a sound level meter. The tests are carried out in rooms suitable for residential use like bedrooms, lounges and kitchens. Test results, which are approved by Building Control and used to sign off the building, are recorded in a report and sent to the client.
Sound insulation testing is essential for these dwelling types:
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.
Property with two or more units
This makes certain that the dwellings have adequate sound proofing.
Redevelopment of a building with a single dwelling into flats
When the development is completed, ADE of Building Regulations should be checked, and sound insulation tested accordingly.
Using designs where Robust Details are not included
Robust Detail Ltd set up the Robust Detail Scheme in 2004 to make sure architect and building designs construct partition walls and floors that comply with Approved Document E sound insulation standards. 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. 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.

Standard division for developments (Scotland)
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.” 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 pass a sound test
All you have to do to pass your sound test is include adequate sound insulation in the design. That way, you save time and cost for repair work and re-test.
