Tinnitus is a symptom defined as a perceived sound in the absence of an external source. Its prevalence is reported to be about 10%-15% of the general population and currently there is no cure for tinnitus. Recent research showed that changes in neuronal activity might underlie tinnitus pathology. Several recent studies, which are in general case-reports, show that tinnitus complaints may be reduced by restoring peripheral auditory neural activity by means of intracochlear electrical stimulation
Conditions
Interventions
This study consists of two parts in which every part investigates a single research question. First the effect of electrical stimulation level (current level) on trinnitus intensity will be investigat

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study variable is the intensity of the experienced tinnitus. Because tinnitus is a subjective phenomenon, its intensity is identified by means of VAS. | — |
Secondary
| Measure | Time frame |
|---|---|
| A secondary study endpoint of the present study is the experienced stimulus intensity, its intensity is identified by means of visual analogue scales (VAS). | — |
