| Measure | Description | Time Frame |
|---|---|---|
| Evaluation whether the novel noise reduction algorithm (NR3) provides different SRTs in noisy situation with speech from front compared to the current implemented "standard noise reduction" (NR1; Comparator) | SRTs are measured with the OLSA test. | 4 weeks |
| Evaluation of subjectively different sound quality attributes/dimensions of the novel noise reduction algorithms versus standard noise reduction (Comparator) |
