Note:

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

b.   Due to construction noise permit commencing from 05/02/2016 19:00, continuous noise monitoring was 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).
