Note:

a.   “*” represents that continuous noise monitoring was not required due to no construction work 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).

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