Design outcomes

Primary

MeasureTime frame
Improvement of subjectively perceived hearing performance in everyday listening situations recorded by the SSQ questionnaire (Speech, Spatial and Qualities of Hearing Scale, Gatehouse and Noble, 2004, Short German Version: Kiessling et al., 2011) with the experimental bimodal provision in comparison to the conventional bimodal provision. Assessment of subjective hearing performance with the SSQ is performed at the start of the study, repeatedly during the study, and at the end of the study.

Secondary

MeasureTime frame
Improvement of speech intelligibility in noise as assessed with the Oldenburg sentence test (Wagener et al., 1999) between start and end of the study. Speech intelligibility is measured with the conventional bimodal provision at onset of the study and with the experimental bimodal provision at the end of the study.
