Eve Air Mobility has published its Visual & Sound Perception study in the USA.
“This study has provided useful insights into the perceptions of eVTOL sights and sounds in urban and suburban environments,” said the company in a press statement. “The results show there were low levels of annoyance from eVTOL sounds when compared to helicopters in the context of local ambient sights and sounds. In terms of visual annoyance, there was an increase of annoyance when the eVTOL was visible during take-off.”
“The study sought to recruit participants who reflected the community’s demographic diversity. Over 100 participants aged 18 to 65 were selected based on broad demographic requirements including but not exclusive to age, gender, residential locations and education levels. The aim was to recruit a representative sample of the local population. The study was conducted in New York City, Orlando and San Francisco.”
Overall, annoyance scores for eVTOL flyovers were low considering the sound level expected from these aircraft. “Participants expressed more annoyance at eVTOL take-off events – where they are 330 ft away from the flight event – when compared to eVTOL flyovers at 1000‑ftabove ground level (AGL).
“During flyover events, there were no differences in aural annoyance ratings with or without the sight of eVTOLs overhead. However, higher annoyance scores were found when the aircraft was visible during take-off. A higher level of annoyance was reported when participants could see an eVTOL taking off compared to when they only heard it.”
