Evaluate the performance of directional microphone systems in binaural (bimodal or bilateral) cochlear implant users
1. To determine the benefit of a CI in the functionally deaf ear of patients with asymmetrical hearing loss with moderate to severe hearing loss in their best ear in terms of speech performance (in quiet and noise) and localization 2. To determine…
There are four main objectives in this research project, belonging to two different parts of the study. Part 1 comprises objectives 1 and 2:1. Determine the electrode discrimination abilities of prelingually deafened adult CI users in order to…
This research project has 2 main goals and can therefore be divided into 2 parts: - The aim of part (A) is to qualitatively and quantitatively assess the daily-life experiences of CI-patients who do or do not wear a contralateral hearing aid.…

The aim of this study is to determine the effects of hearing-aid noise reduction on the perception of normal hearing listener, in terms of intelligibility, listening effort, noise annoyance, speech naturalness and overall preference. Secondly, the…
The aim of this study is to determine the association between pre- and post-operative residual hearing in cochlear implant patients and the intracochear electrode position.
The basic safety of the surgical procedure and the DACS actuator as well as the basic efficacy of the DACS were already shown in the DACS Chronic Clinical Trial (see protocol). The safety of the C-DACS ID receiver/stimulator, which replaces the…
The ENT clinic in Groningen has developed a new speech coding strategy: phase-lock speech (PLS) coding. This strategy distinguishes from existing strategies by the explicit coding of acoustic fine-structure. In normal hearing subjects, the…
to evaluate the effect of hearing aid fitting as a treatment for tinnitus in patients with mild hearing losses and to determine factors that are critical to this effect.
Post-market clinical follow-up of a magnetic bone conduction implant (Cochlear Baha® Attract System)
This post-market clinical follow-up investigation aims to evaluate the usability and the mid- to long-term performance of the Baha Attract System in terms of hearing outcomes and safety. The objective is to compare the hearing performance with the…
There are 2 main limbs to this study:1. Create a benchmark, in which we will assess the three most commonly used Dutch speech-in-noise tests, namely the LIST, Matrix, DIN and Plomp for their associated LE in noise. This is necessary as pupillometry…
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…
Determine speech understanding in noise with the AB*s bimodal BF directional hearing technology.
The main objectives of this study will be to demonstrate that the Sentio system improves hearing on the implanted ear and provides patients with improved speech recognition on the implanted ear. In addition, adverse events related to the Sentio…
The main objective of this study is to conduct a double-blind randomized control trial to assess the efficacy of 3 different amplification schemes of hearing aids in tinnitus patients. The schemes will be adjusted to the individual*s tinnitus…
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…
The main objective of this study is to determine the most precise method for automatic threshold detection of eCAP measurements. Secondary, the correlation between the eCAP thresholds and behavioural thresholds will be examined (the accuracy of the…
