(b) the A weighted sound pressure level exceeds 115 decibels.”;
and
(b) by adding at the end the following sub-regulations:
“(4) For the purposes of sub-regulation (1), daily noise dose shall be calculated—
(a) in accordance with the procedure set out in section 3 of Australian Standard 1269-1983; and
