death and includes the following:
(a)           pneumonia;
(b)           respiratory failure;
(c)           cardiac arrest;
(d)           circulatory failure; or
(e)           cessation of brain function.
                                     time-weighted average (TWA) with a 3-dB exchange rate means the time-weighted average noise exposure level calculated according to the following formulae and shown in the table:

          TWA = 10.0  Log(D/100) + 85
        where D = daily dose; and

        D = [C1/T1 + C2/T2 + …..+ Cn/Tn]  100
        where  Cn = total time of exposure at a specified noise level; and

        Tn = exposure duration for which noise at this level becomes hazardous
