This study presents a comprehensive numerical framework for auralizing multirotor noise during complex maneuvers, incorporating rotor tonal and broadband prediction, synthesis, psychoacoustic analysis. Validation studies various flight scenarios, including single rotors quadrotors, confirm the capability of this in prediction-based analysis configurations. The primary focus research is to assess flyover takeoff multirotors under diverse operating conditions. When tracking mission profile gusty wind conditions, characterized by frequency amplitude modulations induced rotational speed control each rotor. A high-resolution time-frequency conducted highlight these modulation characteristics. Additionally, performed cross- plus-type quadrotor configurations clarify effects profiles control. results demonstrate that variations rotor, influenced contribute distinct acoustic characteristics both physical psychological aspects. synthesized time signal provide valuable insights into impact operational environments on metrics annoyance.
