Sound control is a major consideration in most workplaces and environments around Australia, being a necessary part of providing a safe and pleasant environment for people to work and operate in. In today’s world of technological advancement there is rarely little reason for sound proofing of a noisy machine or environment not to be considered, and in the majority of cases a solution to sound proof can be found.
Historically many people have had to work in noisy factories and environments, consider the mills where operators sat a noisy looms for 12 hours a day, the mines where hammering, blasting and other noisy operations filled the air constantly, and the engine rooms of steam trains where the operators and drivers had to bear the noise of the mechanics of the engines.
Modern sound proof measures involve a number of techniques, where by sound emitted from vibrating machines, air pressure and hydraulic pumps, conveyor belts, bottling lines, high speed tools and machine parts can be reduced or eliminated. Sounding proofing materials can be applied to the machine and its parts to absorb sound caused by vibration, air emission and a variety of other sources in order to reduce the noise as close to the source as possible.
In other cases sound proofing enclosures can be built to enclose a noisy area and produce a noise control solution that prevents noise escaping out into a larger area. A whole machine could be contained within a sounding proofing enclosure, or maybe a room can be fitted with sound proofing materials to contain the sound waves.
Welding is a special operation where not only sound is emitted but also damaging sparks and heat. These nuisances too can be contained by the use of specially designed welding curtains.
