Note:

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

b.   Continuous noise monitoring was also carried out at holidays & evening-time (07:00-23:00 hrs on holidays and 19:00-23:00 hrs on all other days) and night-time (23:00-07:00 hrs of next day).

c.   From 14 to 25 August, the calculated noise level at NSR at the school within Tai Wan San Tsuen were discarded due to a malfunctioning analog input card. The data resumed on 26 August following the replacement of the faulty card.
