The primary objective is to investigate the influence of auditory and non-auditory factors on speech recognition abilities in quiet and in noise in CI users. For this reason we will study the effects of linguistic skills and working memory capacity…
The study objectives are to measure the impact of swimming in chlorinated water on the upper and lower airways of children with and without *doctors diagnosed asthma* by means of the following methods: 1.Tympanometry after otoscopy 2.Airway…
To investigate which surgical technique (with or without vein graft interposition) is most (cost-)effective in patients with otosclerosis in terms of the average postoperative air-bone gap (ABG) closure, individual air and bone conduction thresholds…
First, to measure the influence of the speech coding strategy on frequency discrimination in a free field test. Second, to quantify the influence of the number of harmonics on frequency discrimination in cochlear implant users and in normally…
To gain information about the characteristics of the oVEMP-response in patients with otosclerosis and to objectify the complaints of dizziness pre- and postoperatively through a dizziness questionnaire.
The main objective of this study is to determine a pointprevalence of otitis externa. Further, we want to determine the presence of risk factors and to obtain information about how otitis externa is presented by people with an intellectual…
Social and emotional functioning of hearing impaired children, in the agegroup between 9 and 15 years old.
The present study intends to perform functional magnetic resonance imaging (fMRI) in order to obtain further insight in effects of selective attention on sensory processing. This study aims to compare subjects with normal hearing to patients that…
To assess the effect of bilateral cochlear implantation compared to the standard unilateral cochlear implantation in children with severe to profound hearing loss.
To evaluate the efficacy of various masking strategies in cochlear implants as a treatment for tinnitus in patients with profound hearing loss.
Primary: To find out which areas in the brain play a part in the maintenance of tinnitus, and what the roles of those areas are. This will be done using BOLD response fMRI imaging.Secondary: 1. To find out which areas in the brain play a part in the…
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…
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…

This project examines their relative contribution using pupil dilatation and concentration cortisol and alpha amylase in saliva as objective measures of mental effort and questionnaires. Young and elderly normally hearing and hearing impaired…
The primary objective of this study is to examine the role of linguistic skills in speech understanding. To reach this objective, we will first identify those features of the Dutch language which are affected by congenital hearing impairment.
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.
