Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in the ability of spatial sound localization, measured using a standardized localization experiment in a half-circle loudspeaker array, assessing the three different configurations (own hearing aid [HA] + own speech processor [SP], new HA + new SP, new HA + new SP optimally matched). | — |
Secondary
| Measure | Time frame |
|---|---|
| Change in speech understanding, measured using the German Matrix Test in background noise, assessing the three different configurations. Subjective evaluation of the different configurations in terms of listening comfort and sound quality using a questionnaire. | — |
