Remark: | |||||||
* The unusual noise recording at M6a on 19 August 2014 the L10 was lower than the Leq, which was may be due to the brief burst of higher noise levels from the passing vehicle (cargo truck) in regular speed on the Sassoon Road and stopped sharply near the monitoring location, especially noise monitoring at M6a was at the quiet period. | |||||||
