CRITERIA

Measurements and Calculations

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

•   general requirements of the Queensland environmental protection legislation;
•   Environmental Protection (Noise) Policy 2008;
•   Noise Measurement Manual, Queensland Department of Environment and Heritage Protection,
    Version 4 date 22 August 2013; and
•   Australian Standard AS 1055.1-1997, Acoustics – Description and measurement of environmental
    noise, Part 1 – General procedures.

Noise Limits

The Noosa Council Town Plan does not contain specific noise limits. However, in accordance with the
Environmental Protection (Noise) Policy 2008 the following should be noted:

1. Acoustic Quality Objectives. For the whole of Queensland the acoustic quality objectives are
   target noise levels which should not be exceeded. These are, for residential:

    •    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, daytime and evening:
             o 35 dB(A) LAeq,adj,1hr;
             o 45 dB(A) LA1,adj,1hr; and
             o 40 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;

As it is not possible to assess inside the adjoining residential, the internal noise criteria needs to be
converted to the equivalent external criteria. To assist in converting the interior noise limits to
equivalent external noise limits, reference is made to the Department of Environment and Heritage
Protection Guideline, Noise Control, Planning for Noise Control, Version 1 dated 15 January 2016,
and in particular Table 7. Table 7 nominates different noise reduction levels for various states of
windows wide open, partially closed or completely closed, namely 5 dB(A), 10 dB(A) and 20 dB(A)
respectively. In addition, it should be noted that the ‘partially closed criteria’ protects at least 90
percent of the population from the adverse effects of transient noise, and for this reason a difference
of 10 dB(A) has been adopted to convert the interior noise criteria to the equivalent noise criteria
outside the residences.

Therefore, for the night-time period the equivalent external noise criteria would be:

    •    30 + 10 = 40 dB(A) LAeq,adj,1hr;
    •    40 + 10 = 50 dB(A) LA1,adj,1hr;
    •    35 + 10 = 45 dB(A) LA10,adj,1hr;
