SAFETY SILENCING THE NOISE

This article describes some recent products for road noise barriers, some of which also have special safety features. The French company Veka is using recycled waste PVC plastic to make anti-noise acoustic screens; the modular blocks, forming the completed screens, are available in four colours, and are flexible enough to form a variety of geometric shapes. Veka's system is one of several which use a wide range of materials, such as acrylics, concrete, metal, timber, soil, and plants, to reduce the sound from vehicles, especially near residential areas. The Swedish company Silentia uses lightweight hollow extruded plastic sections, linked by a guide rail, in its noise barrier system. The Noisemaster acoustic control block is said to have exceptionally efficient insulation and noise absorption qualities, due to cavity slot resonators in its block face. ICI Acrylics has developed its Perspex Clearview sheets for noise reduction applications to transport and for sound barriers for residential areas. Stenoak Fencing has produced its own design for reflective timber noise barriers. Highway Care's Hex Foam Sandwich System (HFSS) crash cushion has begun to be used for wide hazard protection in the UK.
