Note: “--“ represents the measured noise monitoring data lower than the established notional background level.

 

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 civil works would tentatively commence in early 2004.  As there would be no construction work during the period from 12/5/2002 to early 2004, the manual noise monitoring at Pak Kok Tsui would temporarily be suspended within this period.
