About this trial
The aim of this clinical study is to investigate how the fitting of an EAS (electrical acoustic stimulation) based on electrocochleography (ECochG) thresholds compares to fitting based on pure tone audiogram thresholds in terms of speech intelligibility in quiet and noise. The personal feedback from the study participants regarding the question of better fitting and the resulting sound quality should also be included in the analysis.
Eligibility criteria
Qualifiers
Patients aged between 18-85 years.
Cochlear Implant (CI) candidates with measurable post-operative low-frequency residual hearing (125Hz <65dB, 250Hz <65dB, 500Hz <65dB).
Only patients with MED-EL EAS.
Written informed consent must be obtained prior to study start.
Disqualifiers
Patients with cognitive impairments who, as a result, lack the capacity to make decisions.
Uncooperative patients regarding pure tone audiometry thresholds measurements.
Morbus Menière or intracochlear/ vestibular schwannoma
Trial design
Treatments tested in this trial
- The objective fitting method of the EAS based on the thresholds of electrocochleography is the intervention of our study.
- The subjective adjustment of an EAS based on thresholds from the pure tone audiogram.
