CRITERIA


Noise Criteria

For the Parkridge development potential noise impact is with respect to the surrounding residential
units, both with respect to balconies and internal habitable rooms.


Environmental Protection (Noise) Policy 2008

In accordance with the Environmental Protection (Noise) Policy 2008, Schedule 1 describes the
following Acoustic Quality Objectives for dwellings:

         Outdoors, daytime and evening:
             o 50 dB(A) LAeq,adj,1hr;
             o 65 dB(A) LA1,adj,1hr; and
             o 55 dB(A) LA10,adj,1hr;

         Indoors, night-time:
              o 30 dB(A) LAeq,adj,1hr;
              o 40 dB(A) LA1,adj,1hr; and
              o 35 dB(A) LA10,adj,1hr;

To enable assessment against the above criteria the indoor criteria requires adjustment to be equivalent
to outside the residential units. For a fully open window the noise level reduction from outside to inside
is 5 dB(A) (Eccoaccess ‘Planning for Noise Control’, Department of Environment and Heritage
Protection, 15 January 2016 refers).

Therefore, the equivalent external noise levels for the night-time period are:

               o   30 + 5 = 35 dB(A) LAeq,adj,1hr;
               o   40 + 5 = 45 dB(A) LA1,adj,1hr; and
               o   35 + 5 = 40 dB(A) LA10,adj,1hr;

In addition to the above the Environmental Protection (Noise) Policy 2008 also describes noise limits to
accommodate ‘background creep’. These noise limits, for time varying noise sources, are ‘background
+ 5 dB(A)’, with the noise limit expressed as the LAeq,adj,T, and ‘T’ has been assumed to be 15 minutes.


Noosa Council Parkridge Approval

In accordance with the Noosa Council Change to an Existing Approval document dated 18 October
2019 (Council reference 132005.1133.10) the following should be noted with respect to noise and the
Facilities Building:

81.       Noise emission from mechanical plant and equipment (air conditioners, refrigeration
          equipment or pool pumps, etc) shall comply with the following requirements:

          a.       A person must not use equipment on any day if it makes or causes noise to be made:
