CRITERIA

All noise level measurements were conducted in accordance with the following:

•    general requirements of the Queensland environmental protection legislation;

•    Environmental Protection (Noise) Policy 2019;

•    Noise Measurement Manual, Queensland Government, Department of Environment and Heritage
     Protection, Version 4.01, 10 March 2020;

•    Australian Standard AS 1055-2018, Acoustics – Description and Measurement of Environmental
     Noise.


NOISE LIMITS

Based on reports previously prepared by the consultant for projects within Noosa Council,
consideration should be given to the acoustic requirements of the Environmental Protection Act 1994
and the Environmental Protection (Noise) Policy 2019 (and previous 2008 version).

In accordance with Schedule 1 of the Environmental Protection (Noise) Policy 2019 the following
Acoustic Quality Objectives should be noted:

     •   Acoustic quality objectives, daytime and evening, external to dwelling:
            o 50 dB(A) LAeq,adj,1H;
            o 55 dB(A) LA10,adj,1H; and
            o 65 dB(A) LA1,adj,1H;

     •   Acoustic quality objectives, daytime and evening, inside dwelling:
            o 35 dB(A) LAeq,adj,1H;
            o 40 dB(A) LA10,adj,1H; and
            o 45 dB(A) LA1,adj,1H;

     •   Acoustic quality objectives, night-time, inside dwelling:
            o 30 dB(A) LAeq,adj,1H;
            o 35 dB(A) LA10,adj,1H; and
            o 40 dB(A) LA1,adj,1H;

In the 2008 version of the Environmental Protection (Noise) Policy there was criteria for ‘background
creep’. Based on other reports prepared by the consultant within Gympie Regional Council, Council
have also required that this noise limit criteria be adopted – refer below for extract from 2008 Policy:

10       Controlling Background Creep

         (1)       This section states the management intent for an activity involving noise.

         (2)       To the extent that it is reasonable to do so, noise from an activity must not be –

                   (a)      for noise that is continuous noise measured by LA90,T – more than nil dB(A)
                            greater than the existing acoustic environment measured by L A90,T; or

                   (b)      for noise that varies over time measured by LAeq,adj,T – more than 5 dB(A)
                            greater than the existing acoustic environment measured by L A90,T.

The above ‘background creep’ criteria are based on the background sound levels, the L A90,T,
expressed as the rating background level (RBL).
