HOW TO IMPROVE ACOUSTIC STANDARDS IN CONSTRUCTION Life during lockdown and the densification of our cities has highlighted how many structures simply aren’t fit for purpose when it comes to acoustic solutions and sound management. In this article, Ben Hancock, Managing Director at Oscar Acoustics, looks at what can be done to improve acoustic standards in construction.

ost modern structures strive for sustainability and fire safety excellence, yet acoustics is an area often overlooked. The problem is widespread – spaces may look beautiful, but are, in fact, uncomfortable and noisy – a far cry from the harmonious environments designers set out to create. The problem is now endemic and synonymous with modern-day buildings – many of us struggle to work or relax because acoustic solutions haven’t been given the attention they deserve. For those living and working in these types of settings, the situation can become dire, leading to long-term health problems such as hypertension, heart disease, diabetes, heart attacks and even strokes.
Raising the bar So how can contractors and architects overcome these issues around noise and sound control? Tackling noise from above is one of the most common sources of complaints. Building Regulations

Document E sets minimum standards for soundproofing residential buildings in England and Wales, however, while these ensure new builds and conversions comply, the standards don’t apply to existing dwellings, leaving hundreds of thousands of previously-built properties with inadequate sound insulation. When noise from above is a problem, the simplest solution is to create an isolated ceiling using acoustic hangers, which work by absorbing the vibrations that cause the transfer of unwanted noise between floors. With the right acoustic hanger, you can install an isolated ceiling entirely from the room below with no disruption to the room above, and with minimum ceiling height loss (as little as 6mm). Specifiers should always look for fire safety accreditation – acoustic hangers should come with a BRE fire rating of over 90 minutes and be compliant with British Building Regulations Approved Document E for airborne and impact sound.
