SCHEDULE 3SUPPLEMENTARY NOISE INDICATORS
Interpretation
10. In this Schedule—
“LA10,18h” is the arithmetic mean noise level in dB(A) exceeded for 10% of each hour over the period 06:00 – 24:00 hours;
“LAeq,16h” is the equivalent continuous sound level in dB(A) that, over the period 07:00 – 23:00 hours, contains the same sound energy as the actual fluctuating sound that occurred in that period;
“LAeq,18h” is the equivalent continuous sound level in dB(A) that, over the period 06:00 – 24:00 hours, contains the same sound energy as the actual fluctuating sound that occurred in that period;
“LAeq,6h” is the equivalent continuous sound level in dB(A) that, over the period 24:00 – 06:00 hours, contains the same sound energy as the actual fluctuating sound that occurred in that period.
