NORMAS OSHA DE RUIDO 1910.95

Nivel sonoro con ponderaciónD = 100 (C(1)/T(1) + C(2)/T(2) + ... + C(n)/T(n)),

Donde:C(n) indicates the total time of exposure at a specific noise level.T(n) indicates the reference duration for that level as given by Table G-16a.

Dosis o porcentaje de exposición al ruido

TABLE A-1 - CONVERSION FROM "PERCENT NOISE EXPOSURE"

OR "DOSE" TO "8-HOUR TIME-WEIGHTED AVERAGE SOUND LEVEL" (TWA)

TWA = 16.61 log(10) (D/100) + 90Donde:TWA=8-hour time-weighted average sound level D = accumulated dose in percent exposure.
