Dynamic assessment of airport noise impact: A case study of Shenzhen airport

Airport noise significantly impacts the quality of life for residents near the Airport. Using dynamic population data, we assessed the exposure proportion-the ratio of people exposed to specific noise levels relative to the total population-and compared it with census data. Our findings show that throughout the day, the dynamic exposure proportion consistently exceeded the static exposure proportion, with the gap between the two narrowing as noise levels increased. The dynamic exposure proportion reached its maximum of 14.2 % at 5 PM, while the maximum difference between the dynamic and static exposure proportions occurred at 2 AM, with a value of 1.88 %. Additionally, we evaluated the spatial and temporal impact of airport noise, validated the developed noise model against the reference cases in ECAC Doc 29 Volume 3, and discussed the influence of fleet composition on exposure proportions. Based on these results, we propose recommendations for noise mitigation.
