Definition
NIOSH noise dose combines sound level and exposure time: 85 dBA for 8 hours is 100% of the recommended daily occupational dose.
Reference value
NIOSH noise dose converts through a formula rather than a simple multiplier.
History & use
NIOSH's 1998 criteria use a 3-dB exchange rate/equal-energy rule. OSHA uses different regulatory criteria, so the systems must not be merged.
Modern use
Modern use is context-dependent and varies by region or measurement system.
