本文介绍了一项研究的结果，评估人类感知的噪声所产生的四个不同的小型四轴无人机（UAV）。这项研究利用了四轴飞行器无人机在悬停和在固定高度恒速飞行时产生的噪声的测量和记录。使用1/2英寸麦克风进行的测量用于计算每个噪声事件的不同噪声度量的范围。噪声记录也使用球形麦克风阵列（Eigenmike系统）。这些录音是使用安装在奥克兰大学一个大型消声室中的3D声音再现系统再现的。37名参与者接受了录音，并被要求评估他们对噪音的烦恼程度，并被要求执行一项简单的认知任务，以评估噪音引起的分心程度。本研究讨论了在测试过程中测量的噪声水平，以及各种噪声指标与烦恼等级的关系。研究发现，烦恼与声压级和响度指标密切相关，并且无人机在同一高度盘旋和飞越时造成的烦恼之间存在非常强的相关性。虽然在认知分心测试中观察到不同情况下无人机噪声引起的分心之间存在一些显著差异，但结果并不确定。这可能是由于在参与者的测试分数中观察到的天花板效应。
This paper presents the results of a study evaluating the human perception of the noise produced by four different small quadcopter unmanned aerial vehicles (UAVs). This study utilised measurements and recordings of the noise produced by the quadcopter UAVs in hover and in constant-speed flight at a fixed altitude. Measurements made using a ½″ microphone were used to calculate a range of different noise metrics for each noise event. Noise recordings were also made using a spherical microphone array (an Eigenmike system). The recordings were reproduced using a 3D sound reproduction system installed in a large anechoic chamber located at The University of Auckland. Thirty-seven participants were subjected to the recordings and asked to rate their levels of annoyance in response to the noise, and asked to perform a simple cognitive task in order to assess the level of distraction caused by the noise. This study discusses the noise levels measured during the test and how the various noise metrics relate to the annoyance ratings. It was found that annoyance strongly correlates with the sound pressure level and loudness metrics, and that there is a very strong correlation between the annoyance caused by a UAV in hover and in flyby at the same height. While some significant differences between the distraction caused by the UAV noise for different cases were observed in the cognitive distraction test, the results were inconclusive. This was likely due to a ceiling effect observed in the participants’ test scores.
