Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Percentage of correctly understood words in the Freiburg speech test in quiet and under noise conditions (measured at signal-to-noise ratios of +5 dB and +10 dB at 65 dB SPL, or 80 dB SPL if necessary). The evaluation is stratified by age group (20–40, 40–60, 60–80, >80 years) and degree of hearing loss (according to WHO criteria: normal hearing, mild, moderate, severe hearing loss). This endpoint serves to quantitatively assess speech comprehension under noisy conditions depending on age and hearing status and enables a direct answer to the primary question. | — |
Secondary
| Measure | Time frame |
|---|---|
| Sentence comprehension threshold (SRT) in the Oldenburg Sentence Test (OLSA) under noise conditions, also differentiated by age and hearing groups. Comparison of the results of the Freiburg Speech Test and the OLSA to evaluate the diagnostic significance of both methods with regard to speech comprehension in noise. Analysis of the relationship between audiometrically determined hearing threshold (tone audiogram) and functional speech comprehension in noise, to identify potential discrepancies (e.g., in older people with normal hearing). Descriptive recording of age-related changes in speech comprehension, independent of pure hearing loss. | — |
