Environmental Noise Level Impact Assessment for Proposed Increase to Bed Numbers for
Flashpackers, 102 and 106 Pacific Avenue, Sunshine Beach                                                Page 11 of 22




All of the above noise limits are complied with for the complete 24-hour day, with no additional noise
control measures required, for the roofed communal area, open communal area and pool and deck.

The only other possible source of people noise is with respect to the Manager’s Unit. If a limited
number of people (2 or 3) were outside the Manager’s Unit sliding glass door talking then their
anticipated noise level would be 50 dB(A) LAeq,adj,T @ 8 metres. At the closest residences to the north-
east this would be:

    •    50 dB(A) LAeq,adj,T @ 8 metres – 4 (distance) – 8 (acoustic barrier) = 38 dB(A) LAeq,adj,T, which
         complies with the noise limits for the complete 24-hour day.

All potential locations for the noise of people laughing and talking, with due consideration of the
increase in the number of guests, comply with the noise limits for the complete 24-hour day.


Plant Noise

In accordance with the 2018 report a 1.8 metre high acoustic barrier was required to control the noise
of the air-conditioning units (Figure 1 of this report refers). As there are no additional air-conditioning
units the noise level of this noise source will not change at the closest adjoining residential and,
therefore, no additional noise control measures are required.


NOISE CONTROL

The existing 1.8 metre high acoustic barrier, located as per Figure 1, is the only physical noise control
requirement to ensure that the addition of 11 guests still results in noise limit compliance for the
complete 24-hour day.


CONCLUSIONS

The existing Flashpacker (backpacker) accommodation located at 102 and 106 Pacific Avenue,
Sunshine Beach is approved for 69 beds, and it is proposed to increase this to 80 beds. This increase
of 11 beds with be achieved by internal reconfiguration only – there will be no changes to any of the
buildings, windows, internal or external walls, doors, etc.

As there will be no change to the current number or location of air-conditioning units, this potential
noise source will continue to comply with the noise limits for the complete 24-hour day.

The increase in the number of guests could result in a slight increase in the number of vehicle
movements on the subject site, and will result in an increase in the noise of people laughing and
talking outdoors.

Vehicle and people noise was calculated to all of the closest adjoining residences and complies with
the noise limits for the complete 24-hour day, with no additional noise control measures required.


RECOMMENDATION

It is recommended that, from an environmental noise perspective, the proposed increase in the
number of beds from 69 to 80 should be approved, as there is no increase in the noise impact to any
of the adjoining residences with the current noise control measures which have been implemented.
