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.
“--“ represents the measured noise monitoring data lower than
the established notional background level.
