The Occupational Safety and Health Administration (OSHA) of United States Department of Labor indicates that if you need to raise your voice to speak to someone 3 feet (=1 meter) away, noise levels might be over 85 dB. OSHA also points out that noise may be a problem in your workplace if you:

  • hear ringing or humming in your ears when you leave work
  • have to shout to be heard by a coworker an arm's length away
  • experience temporary hearing loss when leaving work.
