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…
To further optimize 7.0 Tesla MRI techniques and to develop new MRI techniques that will enable state-of-the-art clinical and cognitive research leading to improved patient care. Whereas some applications of 7.0 Tesla MRI already show improvements…
The primary goal of our study is to map and characterize anatomically and functionally the subcortical structures of the auditory pathway in patients with tinnitus and compare them to controls. To this end, we will use 7 T MRI scanner and measure…
To compare the effect of IT dexamethasone versus IT gentamicin on number and severity vertigo attacks.To compare the effects of IT dexamethasone with IT gentamicin on hearing function, functional level scale and aural fullness.
Primary Objective: in what way, if any, do children with cochlear implants process prosody differently from each other and from normally hearing children?Secondary Objective(s): 1) is there a processing difference between linguistic and emotional…
The objective of this study is to examine the vestibular system in three dimensions. To achieve this goal three experiments are performed. The EyeSeeCam video-oculography is validated with the scleral search coils (international golden standard).…
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…
(this text is taken from the protocol, see protocol for the detailed version)The main objective of the study is to gain insight in the underlying mechanism of tinnitus suppression. This objective will be achieved by comparing the suppressive effect…
To objectify the effect of the VLS-system during daily use regarding postural stability and quality of life.
The main objective of the present study is to investigate the optimal stimulation pattern for tinnitus suppression in a structured way. Our study will focus on two parameters: stimulus level and anatomical stimulation site inside the cochlea.
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..
To evaluate the efficacy of various masking strategies in cochlear implants as a treatment for tinnitus in patients with profound hearing loss.
to measure neural activity of the central nervous system in tinnitus related brain areas in cochlear implant recipients with chronic tinnitus and to determine the relation between this neural activity and the subjective tinnitus experience of…
To gain information about the characteristics of the oVEMP response in patients with BRIC type 1
Evaluation of the effect of treatment with the Meniett in patients with unstable Menière*s disease.
The objective of the study is to determine if a 3D motion platform (to measure vestibular function) and accelerometry and a insole pressure system (to measure balance) can be used in future research on patients with vestibular lesions. For this, we…
To study the effectiveness of low-frequency rTMS in patients with chronic tinnitus.
The objective of he study is to develop and evaluate a dynamic visual acuity test, with an added value over the conventional static visual acuity test. We hope that this test can eventually be used as a (military) selection tool and as a test that…
Clinical evaluation of the effectiveness and safety of the BrainPort Balance Device in the rehabilitation of patients with unilateral vestibular disorders with different etiology. The effectiveness of the device will be compared to natural…
