Remark:
# A correction of +3dB(A) was made to the free field measurement.
* Façade measurement.
^ Averaged baseline noise level recorded at NMS3 Ho Yu College is adopted.
** Limit Level of 70dB(A) applies to education institutes while 65dB(A) applies during school examination period.
	Remarks: Effective from July 2012, the Limit Level at NMS3A was revised to 70dB(A). Daytime noise Limit Level of 70 dB(A) applies to education institutions, while 65dB(A) applies during school examination period.
