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.

c. The limit level was reduced from 70 dB(A) to 65 dB(A) during examination periods on 12-15/1/2016.
