Our clients often get asked for tips in regards to passing their sound testing; here are a few tips to help you pass Building regulations Part E:
Ensure all penetrations are fully sealed where they terminate through floors and they are adequately boxed with acoustic quilt and two layers of plasterboard.
Avoid the use of lightweight blocks in the inner envelope construction as sound will travel both vertically and horizontally from dwelling to dwelling.
The use of resilient suspended ceilings will help improve the performance of the floor partition.
Ensure all support steels/timbers are carefully boxed out where they travel from flat to flat vertically and horizontally.
Use a high quality resilient acoustic membrane on top of the floor to improve the impact performance of a floor.
Ensure that you don’t position sockets back to back in acoustic partitions walls.
There are many factors to consider when considering good acoustic design, and they are usually split up into five key factors. If used together or in various combinations they will improve sound insulation properties over a wide range of frequencies. The main factors are:
Another potential problem can also be down to noise flanking transmission, especially in existing buildings where you are planning to convert offices/large houses into flats. Here are just a few of the potential noise flanking areas:
Windows built very close to Internal partitions
Inner leaf of the external wall
External wall cavities
External façade or outer leaf

If you own or manage an apartment it has a lease agreement that has conditions relating to the changing of the floor construction, then you may require Sound Testing for Compliance with Lease Conditions. We undertake many leaseholder sound tests throughout London and the South East and offer a ‘4 step acoustic package’ to satisfy your lease conditions comprising of the following:
Sample Sound Testing of the existing construction. This offers an accurate overview of the acoustic performance of the existing floor partition/s prior to the commencement of construction works. It also enables us to offer a targeted acoustic design using the sound insulation performance of the existing construction.
Acoustic design review – once we have the performance figures from the sample sound testing have been established, we can forward a design that should improve the performance of the existing floor partition – even if you are changing the floor from a carpet to engineered timber floor finish!
Site Visit – This allows us to check that the installation team is installing the acoustic materials as per manufacturer’s guidelines.
Final Precompletion Sound Testing in-line with Approved Document E. This provides an accurate overview of the acoustic performance of the upgraded partition/s, the results of which can be handed over to the relevant person for sign off.
In most cases complaints are usually raised from impact noise such as foot fall from hard bottomed shoes etc. this is accentuated when the unit above has changed their floor finish from carpet to wood.
If you think you may have a problem with sound in your dwelling and or you have encountered complaints from a neighbour due to modifications you have made to the floor partition then please contact us now we can provide our ‘3 step plan’ to satisfy your units lease conditions, then please contact us now at: firstname.lastname@example.org or phone Darren directly on 07775623464.
Noise damping is the most efficient and effective ways to control vibration and noise radiation at the source. Damping materials lessen this noise by turning the vibration into a low-grade heat. By using viscoelastic materials, it changes the resonant frequency of a substrate. By combining vibration damping materials and sound absorbers a composite acoustic construction can be achieved, that can control both airborne and structure borne noise – the final element for good soundproofing.
It is worth noting that a large number of manufacturers now produce a wide range of systems designed to improve sound insulation in homes and commercial buildings. In all instances, the effectiveness of these materials will vary depending on the situation in which they are installed. When choosing the acoustic product/s, detailed information on the likely sound insulation performance should be requested from the supplier. If you have an existing property you should check the existing construction of the dividing wall/floor partitions and work back from there. You are advised to give careful consideration to the data supplied by a manufacturer before using a proprietary product. it is also worth noting that the sound insulation value/s given for each product will be ‘best case’ as they have been tested in laboratory conditions and not on site – this is usually worse result by up to 3-5 dB) which may be the difference between a sound test pass or failure.
Also when undertaking remedial work to improve the sound insulation, the acoustic materials are often quite heavy which may result in considerable weight being added to the structure of a property. Thus it is essential to check that the ceiling or floor joists can carry the increased loads satisfactorily.
So in a nutshell if you allow for the following four main elements of sound insulation on your acoustic partition design; Decoupling, Absorption, Mass and Damping, your development should pass the sound insulation test at the first attempt.
Careful acoustic design consideration should be used from the offset of the project to ensure your project passes the Sound Testing In London, whether it’s new built or a conversion project to meet the required requirements Building Regulations Part E. Tackling these two aspects involves different construction techniques and careful acoustic design detailing. This is good news for the new residents as it proves adequate levels of soundproofing have been incorporated into the buildings design and construction.
In many cases, sound test failure can also be down to the poor workmanship rather than the acoustic design, that is why we offer a full acoustic package which includes for site survey visits; that way we have the acoustic design and onsite construction covered, reducing the chance of sound test failure.
We offer an acoustic design package, which contains the following elements:
Site Survey Visits – to let us view the existing site construction. This allows us to check for potential problematic construction such as inclusion of lightweight blocks in the existing construction. It also lets us check that the installation teams are installing the acoustic materials as per manufacturer’s guidelines.
Sample Sound Testing – of the existing construction. This offers an accurate overview of the acoustic performance of the existing partitions which enables us to offer a targeted acoustic design using the sound insulation performance of the existing construction.
