Next generation noise control
- A new generation of sound barrier with improved environmental benefits and reduced costs
Research conducted at Loughborough since 2007 has led to a new generation of sound barrier which provides improved environmental benefits and reduced costs – in compliance with EU regulations.
The new technology makes use of Locally Resonant Sonic Crystals (LRSC) – arrays of cylindrical rods which allow light and air to pass through whilst attenuating a wider frequency band than previously possible.
The system’s air permeability reduces the need for expensive cooling plants in industrial units, and means that outdoor structures – which boast a 40% reduction in wind-loading – are more stable than conventional barriers.
The novel LRSC system can be constructed from a range of materials – including re-cycled plastics, galvanised steels and clear poly-carbonates – reducing costs and increasing the range of application, aesthetic and architectural possibilities.
In May 2013, a university spin-out company – Sonobex – was formed to develop and commercialise the research.
Interest in SonoBARRIERTM and SonoENCLOSURETM is growing rapidly – and the research underpinning the innovative technology is already contributing to European policy and improved public services.
The commercial sensitivity of the project has restricted publication, but the research has featured in a number of highly regarded journals including the Journal of the Acoustical Society of America
The research is contributing to the implementation of European public policy
University spin-out company – Sonobex – was formed to develop and commercialise the research in May 2013, making its first sale to the power generation sector just six months later.
