Innovative Solutions to Rail Noise by GRAMM Barrier Systems

摘要

It may seem quiet now given the COVID-19 pandemic with less rail travel but when normality returns so will the noise. METASoundBlok is high-density mineral wool encased in steel panels which provides a lightweight and resilient sound-absorbing barrier. Perforated to protect and maintain the sound-absorptive capability of the fill material which has the highest rating for absorptive at 20 Dla tested to EN 16272. Individual panels can easily be removed and replaced, as they are not bolted, welded, fastened to each other or support posts. METASoundBlok can be manufactured in a powder coated finish with an anti-graffiti coating or it is also available in weathering steel COR-TEN. This is similar to bridges like the Ordsall Chord and can offer a 60-year design life.
