Failed Sound Testing in London?

Failed Sound Testing in London?

When a building fails the Part E Sound Test in London it may be down to a problem with the acoustic construction, this may be down to issues such as noise flanking etc.

Ongoing problems with airborne and structure borne sound are often associated with direct noise flanking transmission through floors and supporting walls and other associated structures such as the external envelope. One common cause of noise flanking and failed sound testing is often associated with the inclusion of lightweight blocks within the construction of the building envelope and/or blocked cavities. It all cases it is essential to establish if your problem is due to direct transmission, flanking transmission or a combination of both so that the most cost effective remedial treatment can be chosen.

Sound Testing in London

Unwanted noise travelling along flanking paths will make the building structure vibrate which causes the sound to radiate into your room. One simple cost effective solution is to build another wall or ceiling in front of the original, but not connected to it (often called an independent wall or ceiling) so it provides isolation between materials.

One way to reduce the chance of flanking transmission is through careful consideration to the design at the start of the project.  Unfortunately, by simply specifying high performance wall and floor partitions it is no guarantee to adequate sound isolation and successful sound insulation testing. APT Sound Testing offer both preconstruction and post construction design solutions to achieve a successful sound testing in-line with Part E of Building Regulations. We also offer onsite inspection services to ensure that the sound insulation elements are being installed as per manufactures guild-lines. Even if both types of sound are emitting through the ceiling/floor then there are some easy installations that should reduce the sound levels and improve your sound test results. By advising on a simple cost effective wall and/or floor upgrade, we are able to forward simple to follow acoustic design reviews, utilising our extensive knowledge of different materials and construction methods

If you have failed a sound test and need acoustic advice on how to overcome the problem then please contact us at or call me direct on 07775623464.

BS8233 Noise Surveys in London

BS8233 Noise Surveys in London

APT Sound Testing have undertaken undertake many BS8233 Noise Surveys in London to comply with local planning conditions.  We are a professional noise and acoustic consultancy firm operating throughout Greater London and the Home Counties.

Our fully qualified and highly experienced engineers provide expert advice and conduct survey analysis into all aspects of sound, such as complying with local planning conditions NEC’s and investigating complaints into excessive noise such as excess plant noise etc.

We have undertaken many BS8233 noise surveys in London  on numerous potential housing and other noise-sensitive sites throughout the Capital and the UK. Our acoustic surveys cater for sites that may be exposed to noise from road, rail or or from noisy industrial activities.

We undertake wide range of services from planning noise assessments through to noise mitigation proposals. Where it is proposed to install new plant or equipment, we undertake noise surveys to determine noise emission limits, in line with Local Authority requirements, and provide advice on mitigation. As a London based company we have an in depth knowledge on complying with London planning permissions and local legislation. Our engineers are expertly suited to carry out noise assessments, with a wealth of experience in assessing the sound impact of residential, industrial and commercial businesses in the community.

Noise assessments and reports should be submitted during the pre-application process and discussions on planning applications. In many circumstances a planning condition will stipulate that a noise survey will need to be undertaken.

Planning noise surveys are normally carried out at the design stage of the project prior to the commencement of construction, this is to allow the acoustic design of the building to take into account the local noise levels. If the local noise levels are excessive then a more robust acoustic twill need to be adopted to mitigate any potential noise problems. Thereafter the local authority may also require post a BS 8182 London noise survey to prove that the noise standards have been achieved within the living rooms and bedrooms.

Sound Insulation Testing in London

APT Sound Testing have a massive amount of experience when it comes to undertaking  sound insulation testing in London. We have the necessary know how and onsite experience to carry out sound insulation testing on a new build or conversion project throughout London for a most competitive prices.

Our engineers carry out the airborne and impact sound test measurements in compliance with Part E of Building Regulations. We have previously undertaken hundreds of sound tests to new build and conversion projects. we also undertake detailed design reviews to ensure our clients achieve a successful sound test.


Our engineers also understand the extra coordination that’s required to test within central London, whether its restricted access and/or parking we have it covered. Many other companies that are based outside London literally double their fees when undertaking sound testing in the capital; as we have an office in London we can afford to charge the same flat fee as we do across the rest of the UK.  Also as we are based in London we can usually arrive on site at the agreed time which often minimises delays to planned noisy works on site. We aim to arrive early and leave early.

We undertake London sound testing on all types of projects from simple flat conversions to large new apartment block developments containing many hundreds of flats. We also undertake sound testing where a lease holder dispute has arisen, which is quite common in London. We can undertake sample sound testing to highlight the existing sound insulation performance of the dividing wall and/or floor partitions to allow for targeted acoustic design to keep cost and delays to a minimum.
