The effect of pulse rate on temporal resolution and speech intelligibility in cochlear implant users
To determine the (in)direct effect of CI pulse rate on speech intelligibility by means of (1) a standard test for temporal resolution: amplitude modulation detection (AMD) at two different modulation frequencies, (2) speech intelligibility tests (…
The objectives of this study are to evaluate the clinical outcome of a cochlear implant (CI) over standard health care therapy with either BAHA or CROSS in patients with SSD and to examine the cost efficiency of cochlear implantation in these…
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…
Hypothesis: PLS will improve speech understanding in noise in comparison to HiRes, an exisiting state-of-the-art speech coding strategy. The objective is to test this hypothesis. A secondary hypothesis is that PLS improves pitch perception. A…
In this research, psychofysical tests will be used to explore in which way the signal processing in CI and hearing aid can be optimized to fully exploit both input modalities in speech understanding, and in sound localization..
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.
To evaluate the efficacy of various masking strategies in cochlear implants as a treatment for tinnitus in patients with profound hearing loss.
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…
Evaluation of the effect of treatment with the Meniett in patients with unstable Menière*s disease.
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…
