NOISE LEVEL IMPACT


Vehicle Noise From Additional Carpark

From the source noise data used in the previous reports prepared for the subject site typical on-site
vehicle noise levels (time varying noise source) would be:

•   car driving on driveway:          46 dB(A) LAeq,adj,T @ 8 m;
•   car door closing:                 48 dB(A) LAeq,adj,T @ 30 m;
•   car engine starting:              48 dB(A) LAeq,adj,T @ 30 m.

For the proposed additional carpark on the south-western side of Block C the closest adjoining
residence is to the north-west, with the residence located towards the rear of the lot and the garages
at the Pacific Avenue end. At this residence, with an intervening boundary 1.2m high concrete block
wall, vehicle noise level impact at the closest habitable rooms would be:

•   car driving on driveway:          46 dB(A) LAeq,adj,T @ 8 m – 8 (24m distance) – 8 (barrier effect of
                                      intervening building) = 30 dB(A) LAeq,adj,T;
•   car door closing:                 48 dB(A) LAeq,adj,T @ 30 m + 2 (24m distance) – 8 (barrier effect of
                                      intervening building) = 42 dB(A) LAeq,adj,T;
•   car engine starting:              48 dB(A) LAeq,adj,T @ 30 m + 2 (24m distance) – 8 (barrier effect of
                                      intervening building) = 42 dB(A) LAeq,adj,T;.

The noise limits for the above noise sources, at the adjoining residence to the north-west, are:

    •    daytime:           47 dB(A) LAeq,adj,T;
    •    evening:           47 dB(A) LAeq,adj,T;
    •    night-time:        42 dB(A) LAeq,adj,T.

The noise limits for the complete 24-hour period are complied with, and this compliance is achieved
with no additional noise control measures required.


People Noise


Block C Upper Floor

The applicable source noise levels are:

    •    8 guests inside a dorm:               64 + 15 x log108 = 77.5 dB(A) LWAeq,adj,T. This is equivalent
                                               to 51.5 dB(A) LAeq,adj,T @ 8m;
    •    6 guests on stairs/walkway:           64 + 15 x log106 = 75.7 = 76 dB(A) LWAeq,adj,T. This is
                                               equivalent to 49.7 = 50 dB(A) LAeq,adj,[email protected] closest residences which could be noise impacted by guests on the stairs leading up to the Block
C upper level dorms, and on the walkway, are those to the north-east. There is an existing 1.8 metre
high acoustic barrier on the north-eastern boundary of Flashpackers Noosa.

For guests inside a dorm on the upper level of Block C, all glazing will be fixed (un-openable) and the
minimum noise reduction achieved from inside to outside a dorm would be 20 dB(A).
