Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study parameter is the degree of bimodal benefit. This is the benefit of wearing a CI in combination with a contralateral hearing aid (bimodal listening) in comparison to only wearing a unilateral CI. Speech understanding in difficult listening situations is still a main challenge for hearing impaired and CI patients in daily life. Therefore speech understanding in noise is considered to be the primary outcome of bimodal benefit. - In part (A) the degree of bimodal benefit will be subjectively assessed using two daily-life disability questionnaires (SSQ and AVETA). - In part (B) the benefit of bimodal listening will be objectively measured on speech understanding in quiet (CNC-score), spatial speech understanding in noise (SSPINtest), listening effort (VAS-test) and the ability to localize sounds (localization test).

Secondary
| Measure | Time frame |
|---|---|
| - In part (A) the secondary parameters are the qualitative experiences of CI-patients with or without a contralateral hearing aid, namely in the field of hearing aid use (bimodal questionnaire) and sound quality (sound quality questionnaire). Part (A) will also measure quality of life in this group of bimodal and unilateral CI-patients by the use of a hearing specific questionnaire (HHQ) and a general health questionnaire (HUI 3). - Part (B) of the study focuses on the identification of more objective-technical factors influencing the degree of bimodal success. Expected contributors to bimodal benefit are residual hearing, device fitting, loudness, spectral-, temporal information and cognition. Therefore multiple secondary parameters will be measured in these fields. See also: Research protocol: 7.1 Study parameters/endpoints | — |
