Evaluate the performance of directional microphone systems in binaural (bimodal or bilateral) cochlear implant users
Primary research questions:1. Does tinnitusspecific- behavioural exposure-treatment (T-BET) decrease tinnitus-related fear, tinnitus-severity and enhance recovery, when compared to a masking-therapy with use of personalised on-ear masking-devices,…
The objective of the study is to answer the following questions:a) Does the PLS-strategy improve pitch- and speech-perception?b) How does the number of harmonics in consecutive channels influence frequency discrimination, in speech coding strategies…
To measure the gap detection threshold in CI users and (NH control subjects) considering the effect with speech-like stimuli using direct stimulation or CI device.
1.To assess if multiple sequentially steered pulses can reach appropriate loudness while main-taining a single percept in cochlear implant subjects2.To compare loudness growth of sequentially steered pulse trains with those of conventional monopolar…
Comparison of hearing preservation and outcome of two fundamentally different cochlear implants designs (LW or PM) and the two most used surgical approaches (RW or CO). Secondly, asses the structure preservation (i.e., scalar position) of each…
To evaluate a new imaging based natural mapping strategy for CI fitting to optimize patient-related outcomes. Compared to conventional clinical fitting, it is proposed that this new method will improve speech understanding and sound perception in…
This traditional feasibility study intends to inform a future pivotal trial in the following two ways. Firstly, it aims to evaluate the potential of neural health metrics triggered by FMS, to predict the implant recipient*s auditory performance -…
The primary objective of this study is to compare the migration rates of the two fixation techniques (bony bed vs. subperiosteal pocket), and assess the feasibility of the techniques, thereby assuring the stability of the implant with the least…
Main objective of this study is to characterize the possible benefits of the new Phonak Marvel CI-CROS device on speech understanding in noise, including its implemented beamformers (UltraZoom and StereoZoom) using different noise setups.
The main objective is to assess the perceived sound quality of different speech and music excerpts that are modified using the dereverberation algorithm by CI users. To this end a suitable graphical user interface (GUI), the MuSHRA, will be…
