Eligibility
Inclusion criteria
Inclusion criteria: - Signed declarations of consent for data protection (for subject selection and for conducting the study), the subject contract and the subject consent form must be available - 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 |
|---|---|
| The primary endpoint is the assessment of the annoyance resulting from aircraft noise and specifically the comparison of the annoyance between the noise to be expected during the take-off and approach of an SST-Airliner and a subsonic conventional A320 commercial aircraft. | — |
Secondary
| Measure | Time frame |
|---|---|
| Further exploratory endpoints are the reported annoyance caused by the noise of the SST business jet as well as the unpleasantness, threateningness and familiarity of the flight noise of all aircraft types. In accordance with the secondary hypotheses (see above), the noise ratings are compared exploratively for different flight procedures (standard vs. PLR) and for different auralization methods (configurations A to D). | — |
