Sound Control-dB Successfully Protects Personnel from Harmful Noise

Company name: NSW Wastewater Facility, AustraliaProject: Ventilation duct applicationCoating used: Mascoat Sound Control-dBThickness: 1.5 mmReason for application: Reduce vibrational noise

Mascoat Sound Control – dB is a multipurpose, spray on sound control coating that has been utilized within industrial applications, for the reduction of vibrational and excessive noise issues within onshore and offshore projects, to areas such as pumps, ducting, generator housings, and more. It tackles the problem of noise by trapping vibrational sound before its airborne release, making it more effective than conventional sound insulators.

To confirm to strict sound regulations, a NSW wastewater facility employed Mascoat’s authorized distributor in Australia to provide the most cost effective solution to reduce excessive noise. The unsafe annoyance was produced by their industrial ventilation ducts, which ran externally throughout the facility. On recommendation, Mascoat’s sound dampening coating was applied to the external surface of these ducts at approximately 60 mils (1.5 mm) in 20 mil coats.

After the coating was applied, there was a significant 8-10 decibel reduction of vibrational noise. The decrease enabled the facility to adhere to site regulations and added to the overall reduction needed to meet surrounding area regulations. The success of Mascoat’s dB application has since lead to approval of the coating’s use in upcoming projects within a similar facility.
