Abstract：As an innovative product integrating multidisciplinary technologies,low-altitude aircraft have rapidly expanded in application scale over the past few years and demonstrate foreseeable potential for further growth.However,low-altitude aircraft are highly likely to become a new source of environmental noise pollution,potentially causing increasing noise-related complaints.To address this issue,this paper reviews the current state of domestic and international research from three aspects:regulations related to low-altitude aircraft noise emissions,noise measurement and analysis,and noise calculation.In the aspect of regulations,the paper introduces the noise emission limits stipulated by the European Union Aviation Safety Agency(EASA)and the United States Federal Aviation Administration(FAA),as well as Chinese governance objectives for low-altitude aircraft noise emissions.In the aspect of noise measurement and analysis,it highlights three standards for noise measurement of low-altitude aircraft both domestically and internationally,and discusses the measurement methods employed in outdoor and laboratory environments.In the aspect of noise calculation,the paper concentrates on model-based and noise propagation-based methods.Finally,the paper analyzes challenges in these aspects and suggests future directions for noise prevention and research in low-altitude aircraft,including broader regulations,standardized measurement guidelines,and enhanced verification,to advance the development of noise control technologies.
