Abstract

Based on domestic research on technologies related to aircraft cabin noise and relevant standards, this study focuses on the sources, generation mechanisms, transmission paths, and control methods of cabin noise in rotor aircraft. Key influencing factors and their effects are analyzed to provide a reference for the further development of cabin noise control in rotor aircraft and the continuous advancement of related standards. The analysis shows that cabin noise in rotor aircraft is characterized by coupling among multiple sources, pronounced low-frequency structure-borne noise, and broadband noise transmission. Accordingly, noise prediction and control should employ coordinated methods tailored to different frequency ranges, with appropriate trade-offs between engineering implementation and standardization.
