TWAeq Calculated from Percent Dose (OSHA)

Sum of the actual exposure at each noise level divided by the allowed time at that level

Formula

  • \( TWA_{eq} = 16.61 \log(\%D/100) + 90\text{dBA} \)
Variable Description
D Sound power level

TWAeq Calculated from Percent Dose (OSHA)

\( TWA_{eq} = 16.61 \log(\%D/100) + 90\text{dBA} \)
TWAeq
= 16.61 * log(
D
/ 100) + 90dBA
