Aug 15, 2013· Note that when noise levels at a worker's two ears are different, the higher level must be sampled for compliance determinations. Keep in mind that your body or surrounding equipment can influence the noise level, acting as a barrier between the noise
Crushers, screens and dust-collection fans all contribute to high noise levels. Air-cooled lubrication systems are not only noisy, but often leak oil. Well-balanced, choke-fed crushers, dust-enclosed screens and dust collector fans with silencers can keep noise levels under control. Recirculating water can be used to cool crusher

This means that noise levels can't be added directly like other numbers. On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound
Personnel are then exposed to higher noise levels than before, despite noise-reducing measures taken in the machine's design. This is because the noise emission rises non-linearly because of higher rotary and travelling speeds in machine parts. For example, for every doubling of the rotary speed the noise emission for rotating print machines
Work practices the right equipment still has to be used correctly; eg make sure doors and windows of vehicle cabins are closed or the correct techniques used when dismantling formwork. Sound barriers stop noise escaping by using temporary shields sound barriers. Use existing objects such as trailers or cabins to stop noise
