日起降100架次以内机场噪声验收监测周期研究

Study on Acceptance Monitoring Period of Airport Noise within 100 Sorties of Daily Takeoff and Landing

本文通过选取日起降约50架次的机场周边2个噪声敏感目标,比较了不同监测周期(连续7昼夜、连续5昼夜、连续3昼夜、连续2昼夜与连续1昼夜)下的计权等效连续感觉噪声级差值大小。结果表明:连续3昼夜与连续7昼夜的计权等效连续感觉噪声级差值在0.4 d B以内,连续3昼夜的计权等效连续感觉噪声级较为准确。

This paper selects the daily airport landing about 50 sorties, 2 noise sensitive target around the airport, compared with the weighted equivalent continuous sensory noise level difference among 7 consecutive day and night, 5 consecutive day and night, 3 consecutive day and night, 2 consecutive days and 1 consecutive day and night. The results show that the continuous sensory noise level difference within 0.4 dB between consecutive 3 day and 7 consecutive day and night, consecutive 3 day and night weighted equivalent continuous sensory noise level are still accurate.
