The objective is to improve the understanding of intracochlear electrocochleography for objective measurement of residual hearing. ECochG responses obtained postoperatively in patients with different aetiologies will be evaluated in concordance…
Our main objective is to assess the effects of hearing impairment on the subjective and physiological stress responses experienced during acoustically and socially challenging real-life settings and relate these to features acquired during…
The impact of communication possibilities on psychosocial difficulties in children with hearing loss
The primary objective of this study is to determine the effect of specific communicative abilities (speech recognition in noise; vocal emotion recognition and emotion expression) in children with hearing loss on their psychological (emotional and…
To examine whether compromised cochlear microphonic (CM) response during cochlear implant surgery results in poorer acoustic hearing preservation compared to preserved CM.
The main objective of the fMRI experiment is to examine differences in the amount of visually evoked activation of the auditory cortex between hearing and deafened adults and between pre- and postlingually deafened adults. The main objective of the…
With a simple set of clinical tests we want to measure speech recognition performance in a group of normal hearing (NH) individuals and in a group of individuals with a specific hearing impairment. The purpose is to determine if and to what extent…
Validate and improve the new experimental algorithm.
A future project will focus on a new platform for at-home monitoring and testing of cochlear implants, developed by one of the manufacturers of cochlear implants, Advanced Bionics (AB). Their Research Application allows for clinicians to read out…
Validating toddler and preschool hearing screening by means of a tablet.
Primary objective: To assess the level of agreement between the following tests:- The minimal frequency difference necessary to evoke an ACC in normal hearing adults and adults with SNHL (ACC threshold).- The just noticeable frequency differences…
The purpose of this study is to investigate the individual characteristics of loudness perception in typical candidates for bilateral hearing aids. Data on spectral loudness summation and binaural loudness summation and their mutual interactions as…
The primary goal of this study is to evaluate the effect of varying stimulation parameters (inter-phase gap, phase duration, en inter-pulse interval) on the nerve and brainstem response and to correlate this to speech perception performance with the…
The use of multiple programs programmed on the CI processor will be compared to the automatic scene analyser (SCAN). The possibilities of performing speech intelligibility tests at home will be examined and implemented in a webbased environment, and…
We measure the speech understanding of children in different acoustic conditions and on different performance levels: the speech recognition threshold (i.e. just intelligible), and a comfortable intelligibility level. We do this because we want to…
This is an exploratory validation study in a small group of subjects receiving a CI to verify if ECoG measurements with AB*s novel ECoG system are useful as an intra-operative tool for soft surgical techniques to spare residual hearing. This trial…
Firstly, comparison of DTI outcome variables between the auditory nerve of a deaf ear with that of a normal ear. Secondly, in patients who receive a CI, DTI measures will be compared to measures derived from electrically evoked compound action…
Main objective: To map the natural course of the visual and hearing deterioration in Usher Syndrome type 2 for upcoming genetic therapy studies.Secondary Objective 1): To determine a. the necessary type of (combined) examinations, b. the sample size…
