6. Confirm tonality calculation of 2dBA;

Calculated tonal adjustment of 0 dB(A) for experienced rider and 1.1 dB(A) for inexperienced
rider. Tonal calculation for inexperienced rider detailed in this report.

Peers lok’ On-site noise level measurements were used to determine attenuation due to distance,

— residences (268, 295 and 374 Tablelands Road). These measurements were conducted with

8. Confirm separation distances to the nearest residences using more recent aerial photography
maps;

Not required as noise level reduction to the closest adjoining residences to the competency
assessment circuit determined by on-site noise level measurements.

9. Comment on the expected effect of noise travelling along the gully to residents and the

other relevant sources (eg. Kawasaki Mule recovery vehicle noted in residents
