Annexures to Submission

        Patrons
Patron noise from the outside area is expected to be dominant over noise from
inside the café/restaurant. The outdoor area of the tenancy could potentially
accommodate 30 people; therefore, it is conservatively assumed that up to 15
people could be talking simultaneously. People talking in a low-noise environment
will typically produce sound pressure levels in the order of 55 – 65 dB(A) at 1m from
the speaker2. Predicted patron noise levels at the nearest potentially affected
receivers are provided in Table 2. The additional attenuation included in calculations
for the apartment overhead consists of insertion loss of 8 dB(A)through the
weatherproof sail (based on measurements on-site using a small speaker as a noise
source), and 5 dB(A) barrier insertion loss from the balcony edge and balustrade.

        Waste Disposal
Noise from waste disposal can be very intrusive, particularly if glass is being disposed
of. Glass bottles being emptied into a bin in an uncontrolled manner can produce
noise levels in excess of 100 dB(A) at 1m. Waste management procedures are not
yet finalized. However, it is apparent that all waste will be removed via the front of
the tenancy.

        Car Parking
The café/restaurant is in an area with ample on-street parking. Car parking
associated with the café/restaurant is therefore not a significant change to the
existing environment.

7. Assessment of Potential Noise Levels and Noise Management

       Music
Music is not a primary driver for the café business and can therefore be manipulated
considerably to suit the ambient acoustic environment without commercial risk.
Music should be played at a level that is difficult to hear from the in front of
adjoining residences.
It is understood that internal speakers only are proposed i.e. no speakers will be
located in the outdoor area. These should be directed inwards when mounted, with
