PROTECTION FROM WORKPLACE NOISE

摘要

The Centers for Disease Control and Prevention estimates that 22 million workers are exposed to potentially damaging noise at work each year. But whether you operate a jackhammer or a drill rig-hearing loss is preventable. If you notice you need to raise your voice to speak to someone 3 feet away, noise levels might be over 85 decibels. Several sound-measuring instruments are available to measure the noise levels in a work area. These include sound level meters, noise dosimeters, and octave band analyzers.
