Speech Perception Performance With Gap-interleaved Stimulation Paradigms
Effect of Gap-interleaved Stimulation Paradigms in Speech Perception Performance of Experienced Cochlear Implant Recipients: a Single-centre, Randomised Controlled Single-blinded Study
研究概览
详细说明
Auditory gaps can be induced in standard CI users by temporarily deactivating one to three electrodes. These gaps can be configured to have different gap durations.
The different variations of auditory stimulation with gaps will be presented to study participants via a standard MED-EL audio processor (Opus 2) bearing conformity marking. The programming of the processor will be performed using standard clinical hardware and software interfaces. These include the hardware interfaces "MAX interface box" and the "Diagnostic Interface Box" (DIB II) as well as the "MAESTRO" fitting software. After programming the respective configurations to the audio test-processor, a clinical word recognition test (Fournier) and a clinical consonant recognition test will be presented to the participants in a sound-shielded chamber using a free-field loudspeaker system.
