While proponents of urban air mobility (UAM) see electrically powered air taxis and delivery drones as innovative solutions to problems many urbanites face, not much research has been done to address the negative impacts that an UAM ecosystem may present to communities, particularly when it comes to noise pollution.
To find out how noise from drones and air taxis might affect the stress levels of people living in areas that adopt UAM, a team of researchers at Nagoya University and Keio University in Japan conducted a study using video and audio recordings simulating a drone flying overhead. As expected, the louder the noise pollution, the more stress the participants experienced. However, while the self-reported stress was reduced along with the noise levels, the researchers found that unconscious stress levels were maintained even after the noise was reduced.
In addition to self-reported responses from study participants, the authors of the study used a Kansei analyzer to determine the stress levels experienced by people as they witnessed a drone flying overhead in the simulation. A Kansei analyzer is a brain wave meter that detects and measures five types of emotions: stress, concentration, preference, calmness, and interest. This technology has previously been used to assess how people feel about certain environments, such as interior decorations in restaurants and the comfort levels of car interiors, as well as choices on restaurant menus.
