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. The unsafe annoyance was produced by their industrial ventilation ducts, which ran externally throughout the facility. Discover the sound world of d&b audiotechnik.

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. Manufacturer for professional PA speakers and audio systems. It tackles the problem of noise by trapping vibrational sound before its airborne release, making it more effective than conventional sound insulators.

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. If you find yourself without access to hearing protection, cover your ears with your hands.Company name: NSW Wastewater Facility, Australia Project: Ventilation duct application Coating used: Mascoat Sound Control-dB Thickness: 1.5 mm Reason for application: Reduce vibrational noise

For example, music played through headphones at the highest volume is often 94-110 dBA. Many devices that children use today have noise levels much higher than 85 dBA. That’s why some workers are required to wear hearing protectors, such as earplugs or earmuffs, while they are on the job. Installing vibration isolation fittings reduces significantly noise radiated by vibrating parts of the machine.

Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss. by doubling the distance from the source inside a workshop the noise level decreases by about 2 - 4 dB(A) or in the open by 6 dB(A). Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Because people can’t hear all frequencies, or pitches of sound, A-weighted decibels (dBA) can be used to describe sound based on what human ears can actually hear. The A-network strongly de-emphasizes sound energy below 500 Hz. Sound is measured in units called decibels (dB), just as height is measured in feet or inches. The sound pressure level of a tone, after filtering by the appropriate network, was labeled dB (A), dB (B) or dB (C), and correlated decently with the perceived loudness. The louder the sound, the more damage it can cause to your hearing, and the quicker this damage will occur.
