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).
