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).
