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.
