6.1          Noise Source Levels – Proposed Development - Noosa Civic
             Village
Table 13 presents the typical noise sources associated with the development with the potential to impact
the nearest noise sensitive receivers. The noise source levels were calculated to one metre and include
corrections for tonality and impulsiveness as per AS1055. The number of events was estimated for a ‘peak’
one-hour time period providing a ‘worst case scenario’ applied to all relevant operating hour time periods.

6.2          Noise Source Levels – Existing Development - Noosa Civic Plaza
Table 13 presents the typical noise sources associated with the existing Noosa civic centre with the potential
to impact the nearest noise sensitive receivers. The noise source levels were calculated to one metre and
include corrections for tonality and impulsiveness as per AS1055. The number of events was estimated for a
‘peak’ one-hour time period providing a ‘worst case scenario’ applied to all time periods.
