            5. NOISE CRITERIA
            Noosa Shire Council Noise Criteria
            The proposed redevelopment site falls within an existing business centre zone and as such the Noosa Shire
            Plan / Division 3 / Business Uses Code describes the council criteria for the development as extracted below:




            Council does not specify specific noise limits therefore noise emissions are assessed to the state Environmental
            Protection (Noise) Policy for sensitive receivers surrounding the redevelopment as described below.

            Environmental Protection (Noise) Policy
            The Acoustic Quality Objectives and the Background Creep requirements of the Environmental Protection
            (Noise) Policy 2008 (EPP Noise) have been used as the assessment criteria for the development. Operational
            activities for the proposed use (i.e. vehicle movements, speaker box noise and plant noise) have been assessed
            against the Acoustic Quality Objectives as shown in Table 5.1.

                 activity
            Introduced plant have the potential to increase background noise levels in the area. These have been assessed
            against the Background Creep requirements of EPP Noise.

            To the extent that it is reasonable to do so, noise from an activity must not be:
                     •    For continuous noise (e.g. fan noise) – Measured by LA90,T more than nil dB(A) greater than the
                          existing acoustic environment measured by LA90,T.
                     •    For noise that varies over time (i.e. vehicle movements, speakerbox) – Measured by LAeq,adj,T more
                          than 5 dB(A) greater than the existing acoustic environment measured by LA90,T.
            Noise emission limits for the control of background creep, based on measured background levels are shown in
            Table 5.2 below.
