Note:
1.
The
noise generated from local noisy events (e.g. dog barking, passing-by
pedestrians, motor vehicle, aeroplane, helicopter,
etc.) was manually removed during measurement as far as practicable.
2.
กง--กง
represents the measured noise monitoring data lower than the established
notional background level.
3.
The scheduled manual noise monitoring
on 24/3/2005 was missed. A makeup noise measurement on 13/4/2005 has been arranged.
