Describe some impacts of noise in the workplace.

Specific answers will vary, but should include some of the following. High levels of sound will damage hearing. Extended periods of exposure to decibel levels above 85 dB are permanently damaging. (Private business offices average about 50 dB.) OSHA requires ear protection if exposure to 85dB equals or exceeds 8 hours. Even at low levels, noise and vibration can be distracting and can raise a person's blood pressure, so most managers make substantial effort to reduce noise and vibration through good machine design, enclosures, or insulation. Finally, recent research shows that noise in the work environment can increase the risk of heart attack by 50% or more.
