Environmental Noise Level Impact Assessment for Proposed Medical Centre, 45 Maple Street, Cooroy            Page 5 of 20




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 2019;
   Noosa Council’s applicable planning criteria;
   Noise Measurement Manual, Queensland Government – Environmental Protection Agency, Version
    4, August 2013; and
   Australian Standard AS 1055-2018, Acoustics – Description and Measurement of Environmental
    Noise.

Noise Limits

Noise from the proposed medical centre has the potential to noise impact the adjoining residential uses.
The Noosa Plan does not contain any specific noise limit criteria relative to this proposed development
and, therefore, the requirements of the Queensland Environmental Protection legislation has been relied
upon.

In accordance with the Environmental Protection Act 1994 Default Noise Standards the noise limits for
air-conditioning units (same noise limits assumed for any exhaust fans as well) are:

        daytime (0700 to 1800 hours):                   background (LA90) + 5 dB(A);
        evening (1800 to 2200 hours):                   background (LA90) + 5 dB(A);
        night-time (2200 to 0700 hours):                background (LA90) + 3 dB(A).

In accordance with Schedule 1 of the Environmental Protection (Noise) Policy 2019, the Acoustic
Quality Objectives criteria are as follows:

        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;

For the night-time period the internal noise criteria needs to be converted to be equivalent to outside the
closest residential. Allowing a 5 dB(A) noise level reduction from outside to inside (based on all of the
windows fully open and in accordance with the Queensland Environmental Protection Agency
Ecoaccess Guideline Planning for Noise Control) the internal criteria would be equivalent to the
following levels external to the dwelling:
