Figure 1.3.Determining the project-specific noise levelsMeasure existing noise levels (Section 3)i.e. existing background (L A90) (Section 3.1) andexisting ambient industrial noise (L Aeq) (Section 3.2)Where the proponent desires, moredetailed monitoring and analysis linkingexisting noise levels and weatherconditions can be made.(Section 6.3.1)Determine representative existing noise levels frommeasured levels (Section 3)i.e. rating background level (RBL) (Section 3.1.2), existingambient level (Section 3.2)Determine intrusiveness criteria (Section 2.1)i.e. L Aeq,15 minute≤ RBL plus 5 dBDetermine alternative intrusivenesscriteria for specific weather conditionsidentified in any detailed monitoringanalysis that was done.Determine amenity criteria (Section 2.2)1. Determine type of receiver (Table 2.1, Sections 2.2.1 &2.2.2)2. Determine acceptable noise level (ANL) for receiver, L Aeq,period(Tables 2.1 & 2.2)3. Amenity criterion is either:• 'ANL' where existing ambient level is more than 6 dBbelow ANL; or• '< ANL' where existing ambient level isbetween ‘ANL+1 dB’ and ‘ANL – 6 dB’; or• 'existing ambient level minus 10 dB' where existingambient level is greater than ‘ANL+1 dB’ and existingnoise levels are unlikely to decrease in future; or• 'ANL – 10 dB' where existing ambient level is greaterthan ‘ANL+1 dB’ and existing noise levels are likely todecrease in future; orDetermine alternative amenity criteria forspecific weather conditions identified inany detailed monitoring analysis that wasdone.• 'existing traffic noise level (L Aeq, period) minus 10 dB'where existing traffic noise level is ≥ 10 dB above ANL(high traffic criterion, Section 2.2.3)Project-specific noise levels applicable to projectThe lower of the intrusive criterion andthe amenity criterion.Note: Dotted line indicates an optional processNSW industrial noise policy10
