4. Data processing
4.1 Data validation
Each day, the time trends in sound levels L A,eq,1s measured the previous day for each measuring station are visualized (see figure 10 ). High levels (> 90 dB(A)), shown in green, correspond to automatic control levels, while periods shown in orange correspond to the coding of acoustic events attributable to air traffic. The level displayed corresponds to the maximum level (L A,eq,1s,max ) of each acoustic event.
