- Primary Outcome Measures
Name Time Method The key outcome measure according to the primary hypothesis is the probability of being acutely highly annoyed (%HA) by LAeq from drones in hover.
- Secondary Outcome Measures
Name Time Method Due to the different noise generation of a drone during overflight, the likelihood of being acutely highly annoyed by drone overflights is also investigated by the SEL. Since the acceptance and pleasantness of noise was recorded in most of the laboratory studies, these psychological target variables should also be recorded here in order to ensure comparability of the results. <br>be recorded to ensure comparability of results. Therefore, the <br>Probability of acceptance and pleasantness due to increasing LAeq<br>of drones in hover phases and by the increasing SEL of drone overflights will be determined. In addition, the influence of drone type, operating altitude as well as speed (only for overflights) on the subjective perceptions (annoyance, acceptance and pleasantness) will be exploratively investigated.<br><br>
