Development of Low-Fidelity Noise Propagation Module for Urban Air Mobility Noise Impact Assessment

Since UAM eVTOLs operate within urban areas, it is necessary to quickly and accurately predict the noise impact. In this study, a new noise propagation module using tabulated aircraft noise data according to its operating state and distance (NPD data) is developed. This module is highly flexible and scalable while following aircraft noise impact assessment standards. The module can provide several noise metrics, real-time noise propagation images, and the effect of different adjustments. Validation was conducted with FAA's AEDT and NASA's AIRNOISE, and the results of applying NASA's 3rd gen UAM eVTOL NPD data were presented. The module is expected to be used in various research of the integrated operation of the UAM ecosystem.
