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.
使用无人机（UAV）的可能性正在迅速增加。随着电池技术、通信、导航、监视以及一般自主系统的发展，许多无人机预计将在相对较低的高度运行。因此，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，我们对两种不同性能（四旋翼和六旋翼）的无人机在上下飞行、悬停和飞越过程中的噪声进行了测量。经过听力测试证实且在进行无人机噪声测量期间参与了调查的听力良好的受访者对无人机噪声感知进行了主观评估。对无人机噪声测量和主观受访者评估进行了分析和关联。无人机噪声分析表明，在上下飞行和飞越过程中，在相同测量点测量的六旋翼参数高于四旋翼。两种无人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声，并且对六旋翼的体验普遍更差。无论噪声感知如何，超过 80%的受访者认为将无人机引入日常生活的好处多于坏处。
