Remarks  
*  +3dB(A) Façade effect correction included  
# - Limit Level of 70dB(A) applies to education institutes while 65dB(A) applies during school examination period.  
** Construction noise level is only calculated when Measured noise level (Leq) > Baseline noise level.   
    If Measured noise level < Baseline noise level, Corrected noise level = Measured noise level
