noise level mining

noise level mining

Sound Level: Noise known as amajor health hazardisspot specific in case of underground miningwhere the operators are exposed to continuous background noise while high level short duration noise peaks are common in case of surface mining. The human ear is most sensitive in 2 to 5 KHz range and less sensitive in high and low frequencies.
