使用无人机（UAV）的可能性正在迅速增长。随着电池技术、通信、导航、监视和自主系统的发展，许多无人机预计将在相对较低的高度运行。由此可见，无人机噪声对人类健康和福祉的影响问题将更加突出。在本文中，我们进行了两个不同性能的无人机（四旋翼和六旋翼）的噪声测量，在飞行上升和下降，悬停，飞越程序。通过听力图测试确认听力良好并在无人机噪声测试过程中参与调查的被调查者对无人机噪声感知进行了主观评价。无人机噪声测量和主观受访者的评价进行了分析和相关。无人机噪声分析表明，在升降和飞越过程中，六旋翼无人机在同一测点测得的参数高于四旋翼无人机。两架无人驾驶飞机的噪声频谱中都存在低频噪声。参与者能够区分无人机的噪音，并且对六旋翼飞行器的体验总体上更为负面。无论噪音感知如何，超过80%的受访者认为将无人机引入日常生活的利大于弊。
Possibilities to use unmanned aerial vehicles (UAVs) are rapidly growing. With the development of battery technologies, communication, navigation, surveillance, and autonomous systems in general, many UAVs are expected to operate at relatively low altitudes. Thus, the problem of UAV noise impact on human health and well-being will be more pronounced. In this paper, we conducted noise measurements of two UAVs of different performance (quadrotor and hexarotor) in flying up and down, hovering, and overflight procedures. Respondents of good hearing who were confirmed by audiogram measurement and had participated in the survey during UAV noise measurement gave their subjective assessments on the UAV noise perception. UAV noise measurements and subjective respondents’ assessments were analysed and related. UAV noise analysis showed that the parameters measured at the same measurement point for the hexarotor were higher than those for the quadrotor in flying up and down and flying-over procedures. Low frequency noise was present in the noise spectrum of both drones. Participants were able to distinguish between the noise of UAVs and had a generally more negative experience with the hexarotor. Regardless of the noise perception, more than 80% of the respondents believe there are more pros than cons for UAV introduction into everyday life.
