Note: “---“ represents the measured noise monitoring data lower than the established notional background level, particularly for the period of 01/12/2016 07:00 – 22/12/2016 19:00. The Ash Lagoon noise monitoring station was in normal operation but there were no data of calculated noise level at NSR at Long Tsai Tsuen/Hung Shing Ye.

Note:

a. “---“ represents the measured noise monitoring data lower than the established notional background level, particularly for the period of 01/12/2016 07:00 – 22/12/2016 19:00. The Ash Lagoon noise monitoring station was in normal operation but there were no data of calculated noise level at NSR at Long Tsai Tsuen/Hung Shing Ye.

b. 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) under construction noise permit.
