4.2        Noise Criteria

           Under the Sunshine Coast Regional Council’s Noosa Region’s Transport, Roads and Drainage
           Code road traffic noise is only to be considered where a residential development is adjacent to
           a major road. It is noted that the noise levels recorded from the traffic noise on Ben Lexcen
           Drive are below the levels limiting levels of the commonly accepted Department of Main
           roads traffic noise limits at the facades of affected premises. If a traffic growth rate of 3.5% per
           annum is assumed, a commonly accepted default value, the increase in traffic noise will be 1.8
           dB over a 10 year period, the noise level is still below the DMR limits,

           Accordingly the impact of road traffic noise on the development is not considered further.




5.0        MECHANICAL PLANT EMMISION NOISE

           Designs for mechanical services have not yet been completed and plant selections and
           locations are unknown. Therefore, we are only able to recommend design limits for the
           control of mechanical plant noise emissions at the nearest noise sensitive receptor.

5.1        Noise Emission Criteria

           Under the Sunshine Coast Regional Council’s Noosa Region’s Residential Uses Code Section
           14.50 Overall outcomes for the Residential Uses Code stipulates:

           g) provides residents with a high degree of privacy and protection from noise, lighting and other
           environmental nuisances;

           It is accepted that this objective is achieved if the noise emissions of mechanical plant,
           measured at a noise affected place, are limited to the background noise levels plus a margin.
           The criteria and resultant limits are presented in Table 5.




11 L Aeq (24 h our) refers to the equivalent of energy-averaged noise level averaged over a 24 hour period
12 LA90 (18 hour) refers to the noise level exceeded 90% of the time during the period 6:00 am and midnight
13 L A90 (8 hour ) for a specified time interval, means the arithmetic average of 8 individual L A90(1h our) levels measured between 10:00 pm and 6:00

am on the day
