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

b. MANUAL NOISE MONITORING DATA

The hoarding works for the construction of transmission system at Pak Kok Tsui were completed on 11/5/2002. The dredging work near seashore of Lamma landing points would tentatively commence in May 2004. As there would be no construction work during the period from 12/5/2002 to May 2004, the manual noise monitoring at Pak Kok Tsui would temporarily be suspended within this period.
