      This standard specifies the environment standard for aircraft noise around airports, which is applicable to areas affected by aircraft passing noise. The weighted equivalent continuous sensory noise level (LWECNW) for one day and night is used as the evaluation quantity, and the unit is dB. This standard refers to GB 9661 "Measuring method for aircraft noise around airports" to ensure the standardization and accuracy of aircraft noise measurement.
