Definitions for "TWA"
An allowable exposure concentration averaged over a normal 8-h workday or a 40-h workweek.
Time Weighted Average. The yardstick used by the Occupational Safety and Health Administration (OSHA) to measure noise levels in the workplace. It is equal to a constant sound level lasting eight hours that would cause the same hearing damage as the variable noises that a worker is actually exposed to. (This hearing loss, of course, occurs over long-term exposures.) Same as LOSHA.
Time Weighted Average. The average concentration of a chemical in air over the total exposure time - usually an 8-hour work day (see " What are exposure limits?", Understanding Toxic Substances, page 22).
