Attachment 6 - Acoustic Report (Updated) 20.08.2020 · OPW20/0145

1    INTRODUCTION

Acoustic Logic consultancy (ALC) have been engaged to conduct an assessment of major noise source
impacts from the Noosa Civic Shopping Centre onto proposed adjacent residential development.

The report is in response to the Council’s request:

    1.   Prepare and submit to Council for approval with and Operational Works application a revised acoustic
         report which includes measures to mitigate noise generated from the shopping centre operations and
         equipment, including deliveries, truck movements and rubbish collection. This report should consider
         attenuation at the noise source as well as a noise barrier along the shared boundary of Lots 19 and
         21. All measures to mitigate noise must be implemented prior the submission of the subdivision plan
         to Council.
         Noise attenuation is required to achieve the following acoustic quality for potential residential uses on
         Lots 17-19. The measurement location must include receivers being places at the closest point to the
         future residential and office buildings.


                                                                   Criteria (measured at the receptor) dB(A)

         1
         Acoustic descriptor/noise target for continuous noise sources (eg. Mechanical plant).
         2
         Acoustic descriptor/noise target for transient impacts arising from loading dock activities (e.g. truck
         movements, reversing alarms, compactor, trolley etc.)



The purpose of this assessment is the following:

    •    Establish the predicted intrusive noise levels at the proposed subdivision site on Hofmann Road for
         lots 17-21.
    •    Provide acoustic attenuation recommendations to meet the indoor acoustic criteria set by Noosa
         Shire Council. These are applied at the source, boundary and receiver.

This report includes attended and unattended noise measurements from the previous ALC acoustic report
(ref: 20191414.1/1501A/R2/SS, dated 15/01/2020).
