[3] [10] Although specific regulations vary across the world, most workplace best practices consider 85 decibels (dB A-weighted) averaged over eight hours per day as the highest safe exposure level for a 40-year lifetime. Using an exchange rate, typically 3 dB, allowable listening time is halved as the sound level increases by the selected rate.
