Monitor Your Sound

Sound pressure levels are measured in decibels (dB). Guidelines for safe levels of sound exposure are expressed in dB(A), a frequency-weighted measure
of sound pressure, and averaged over time as a time-weighted average (TWA). The National Institute for Occupational Safety and Health (NIOSH) guidelines are stated in terms of the maximum time that you can safely be exposed to different TWAs on a daily basis over a 40-year period.

Exposure to 115 dB for any duration
may pose a serious health risk.

Hearing Conservation Tips

• Avoid hazardous sound environments. Otherwise, wear hearing protection devices (HPDs).
  

• Monitor sound pressure levels above 85 dB. In the absence of a sound meter, the general rule to follow is that if you are in an environment where you must raise your voice to be heard, you may be risking permanent, hearing loss and you should limit your exposure.
  

• Take 15-minute "quiet breaks" every few hours if you are exposed to sound pressure levels above 85 dB. Refer to the guidelines above for safe exposure durations.
  

• Musicians and other live entertainment professionals should avoid practicing at "concert hall levels" whenever possible.
  

• Have your hearing checked annually by a licensed audiologist.
