Conditions

Assessment of the noise impact of small aircraft with electrified distributed propulsion systems on humans

Interventions

Group 1: Sub-study 1: Focused listening test in the laboratory The test subjects are presented with 80 different sounds lasting 15 seconds via a computer with closed headphones in ME's sound laborator

Eligibility

Sex/Gender

All

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: - Availability of the signed declarations of consent for data protection (for subject selection and for conducting the study), the subject contract and the subject consent form - Sufficient knowledge of the German language - age-appropriate normal hearing in the frequency range 125 - 8000 Hz

Exclusion criteria

Exclusion criteria: - Hearing loss in the audiogram: i.e. the hearing thresholds in the better ear are higher than the 10th percentile of the gender- and age-specific hearing thresholds in ISO 7029 (2017) - Wearing a hearing aid - Hearing disorders (tinnitus with severity > 2, sudden hearing loss within the last 10 years) - any other condition which, in the opinion of the doctors conducting the test, makes the subject unsuitable - any medication with an influence on the test parameters or consumption of stimulants and drugs with an influence on the test parameters, e.g. drug consumption, increased alcohol consumption and nicotine consumption that does not allow abstinence for at least 10 hours - persons without legal capacity and persons with limited legal capacity - do not speak German

Design outcomes

Primary

Measure	Time frame
Annoyance due to Air Taxi fly-overs. Ratings are compared between a positive, neutral and negative framing.	—

Secondary

Measure	Time frame
Further explorative endpoints are the stated noise ratings for unpleasantness and the auditory impression of the overflight noise described by means of a semantic differential. In accordance with the secondary hypotheses (see above), the noise ratings are compared exploratively for different air taxi configurations, psychoacoustic indicators and settings.	—
