  • 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.

Impact

  • Academic publication 

    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

  • Public policy 

    The research is contributing to the implementation of European public policy

  • Sonobex 

    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.
