CMS Acoustics Refines Sound Solution
CMS Acoustic Solutions has helped ExxonMobil to comply with the Noise at Work Regulations by isolating the noise output from two industrial fans at the Fawley Oil Refinery, the largest oil refinery in the UK. Providing a bespoke solution comprising SuperLag QuietSlab Laminate, a high performance acoustic lagging material, with an inner core of CMS weight-enhanced Acoustic Barrier, CMS Acoustics specifically targeted the high levels of low frequency sound, significantly reducing the noise generated by the fans.
To control the low frequency-biased sound, CMS Acoustics recommended and supplied the SuperLag QuietSlab Laminate with Acoustic Barrier Type WB10 combination for the fan casings and associated ductwork. Creating a multi-layered, high performance system, two layers of 250mm thick SuperLag QuietSlab Laminate with a core of 5mm Acoustic Barrier Type WB10, were bonded onto the fan casings and ductwork.
A direct coupled lagging system, SuperLag QuietSlab Laminate comprises long-stranded mineral fibres thermo-set with resins for the absorption of sound at the surface, as well as a high mass inner acoustic barrier core to reduce the transmission of sound through the material.
Manufactured from a weight-enhanced, high-density material, Acoustic Barrier Type WB10 provides a flexible and cost effective treatment for chemical and refinery applications. In total, 1,000m2 of the SuperLag QuietSlab Laminate/Acoustic Barrier Type WB10 materials were installed around the fans and ductwork to achieve the high levels of sound reduction required.
