            important and most demanding requirement. Research has determined that the maximum noise
            level inside a bedroom or sleeping area due to short duration transient events should not exceed

            4SdBA LAmax for nil sleep disturbances9. This value corresponds to the World Health Organization

            (WHO)guideline internal LAmax noise level of 4SdBA for transient noise events in order to prevent
            sleep disturbancelO.


            By historical convention, the sleep criteria are applied only during the "normal"sleep period which
            extends from lOpm to 7am.


            To convert the criterion for        sleep disturbance from       a   limit measured inside       a   bedroom to      an


            outdoor limit, adjustments between SdBA and lOdBA                    are   suggested by     various authorities to

            account for fa ade attenuation provided          by a normal, naturally-ventilated dwelling. This results in

            an    outdoor noise limit ranging from SOdBA to SSdBA (LAmax)’


                         Table 4: LAm.x Noise Criteria for car park noise emissions at residences


                                                                 Transient Noise Criteria,
                                            Time Period
                                                                         LAm.x,.dj (dBA)

                                          Day (7am to 6pm)                    69

                                     Evening (6pm to lOpm)                    65


                                      Night (lOpm to 7am)        50 to 55 (sleep disturbance)




            It can be seen in Table 4 that the most stringent noise limits are during the night-time period.




7.2         Limits for service and delivery vehicle noise


            Loading    activities   involving   noise   from   vehicle   refrigeration plant and engine idling             can   be

            characterised    as   being   intermittent or   quasi-continuous in        nature.   However, activities such        as


            vehicle reversing (i.e. reverse beeping         nOise), starting of vehicle engine, vehicle door slamming,
            vehicle acceleration, dropping of boxes (stock) onto the floor, etc. can be characterised                    as   being

            transient in nature.




            Therefore, the appropriate measurement parameters to quantify noise                       events associated with


            loading activities would be LAmax (for transient noise events) and LAeq (for intermittent or quasi-
            continuous noise events). The applicable noise limit for the LAmax noise descriptor would be those

            presented in Table 4 derived for carparking.


           The LAeq noise limits for the residences near the proposed              shopping centre development site due

            to refrigerated truck noise (i.e. from        refrigeration plant on trucks loading / unloading at the site)

            are   determined based     on   the comparison of like parameters methodology              (details regarding this
