Our unrivalled expertise has been gained via extensive research and development, both at our own acoustic laboratory and through the close links we have established with acoustic specialists at Napier, Sheffield Hallam and Heriot-Watt universities. The end result is that we...

The Acoustic Problem Fundamentals of Sound Transmission Impact Sound In buildings, noise travels in two main ways. One is impact- or structure-borne sound. This is where mechanical or kinetic energy is being imparted directly to the structure as the result of steady vibrations or impacts. These are then transmitted to other rooms in the building, causing a partition, structure or surface to vibrate, thereby creating sound. The main sources of structure-borne sound are people (footsteps, slamming doors etc), plant machinery, services and household appliances. Airborne Sound Airborne sound...

Meeting performance requirements & Robust Details Unwanted noise is a disturbing aspect of modern life, and is often a significant nuisance within buildings, with domestic dwellings particularly vulnerable to noise transmitted from attached properties. Pre-completion testing is one of the biggest impacts in the Approved Document, as it is required to be carried out on 10% of dwelling types in each development in order to prove compliance. Where pre-completion testing is required, separating walls and floors must not only have improved design detailing, but also be designed to include the...
