School ensembles, church bands, big orchestras and live music venues - how do you stay within safe sound level limits?

A person conducting a business or undertaking (PCBU) must ensure that workers are not exposed to noise that exceeds the exposure standard for noise. The exposure standard for noise is defined in the WHS Regulation as LAeq,8h of 85 dB(A) or an LC,peak of 140 dB(C).

Which means the following levels are the limits for the time periods shown

8h 85 dB(A)

4h 88 dB(A)

2h 91 dB(A)

1h 94 dB(A)

0.5 97 dB(A)

0.25h 100 dB(A)
