摘要

Numerous studies have been conducted on the implementation of urban air mobility (UAM), yet few have focused on establishing noise evaluation standards for UAM. This study aims to address this gap by initiating the development of noise criteria for UAM and vertiports. The process involves scientific modeling prior to the demonstration phase to ensure a comprehensive understanding of potential noise issues. To achieve this, UAM noise levels were projected using a hemisphere noise propagation model and SoundPLAN software at a potential vertiport site in Seoul. Additionally, UAM noises were compared with helicopter noises. The UAM noise was calculated under various operation conditions including departure, level flight, and arrival. Upon comparing various noise evaluation criteria, it was found that the average equivalent noise level (Leq) of UAM is 15 dB lower than that of helicopter. Furthermore, it does not exceed the current noise standards and regional environmental noise regulations. However, it is worth noting that the maximum noise level (Lmax) of UAM exceeds the environmental noise regulations, although it is 10 dB lower than that of the helicopter noise. In conclusion, for the successful integration of UAM into urban areas, it is essential to establish suitable noise standards.
