Note:

1.    There were no data at NSR at the school within Tai Wan San Tsuen on 11/07/2004 and 27/07/2004 at 23:00-07:00 due to failure of Ching Lam noise alarm station.

2.    กงกX-กง represents the measured noise monitoring data lower than the established notional background level/discarded under strong wind.

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.
