Design outcomes
Primary
| Measure | Time frame |
|---|---|
| •Speech intellegibility with CI and contralateral CROS device versus CI and unaided contralateral side •OLSa measurment in dB in noise •unilateral CI recipients | — |
Secondary
| Measure | Time frame |
|---|---|
| •Comparison of different device configurations (CI only, CI + CROS, CI + HA, CI + CI) in terms of differences in speech intelligibility in quiet •Comparison of different device configurations (CI only, CI + CROS, CI + HA, CI + CI) as well as different microphone options (omni, UltraZoom, StereoZoom) in terms of differences in speech intelligibility in stationary speech shaped noise •Comparison of different device configurations (CI only, CI + CROS, CI + HA, CI + CI) in terms of differences in localization abilities. | — |
