In any work environment, there can be many reasons to keep sound levels within a reasonable range. Sound levels above this range are perceived as "noise." Noise can distract the workforce, creating an unsafe workplace. Or, worse yet, it can cause hearing loss.
A worker distracted by noise may become less production and even irritable. If noise levels are too loud, the worker may not be able to hear warning signals or instructions. High noise levels over prolonged periods of time can lead to permanent hearing loss. When any of these conditions exists, it is important to control, contain, reduce, or eliminate the noise source so a safe work environment can be maintained.
