Noise exposure is typically measured in decibels (dB) using sound level meters or dosimeters. The measurement considers both the intensity and duration of noise exposure. For instance, OSHA's PEL for noise is set at 90 dB for an 8-hour workday, while NIOSH recommends a more conservative REL of 85 dB for the same duration. These measurements help in assessing the risk and determining appropriate noise control measures.
