The main objective is to identify the source of the *musician effect*, particularly for speech perception. The underlying processes involved and individual differences in different groups of participants in speech and music perception, both in quiet…
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…
To report the natural history of retinal degeneration in patients with biallelic mutations in the USH2A gene; to identify sensitive structural and functional outcome measures to use for future multicenter clinical trials in USH2A-related retinal…
To determine the prevalence of BPPV in the elderly patients with an increased risk of fallsSecondary ObjectivesTo compare the outcomes within BPPV patients before and after successful treatment with a canalith repositioning manoeuvre (CRM):* The…
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…
The main objective is to improve the existing techniques for measuring the tinnitus pitch in patients, by exploring both the frequency dependence of the residual inhibition and the contrast gain control effect in the auditory system. Behavioral…
Study the long term effects of frequent exposure to high sound levels on hearing status in orchestral musicians. To assess the hearing condition, several clinically available tests will be used, but for the assessment of diplacusis a new test is…
Primary Objective: To investigate, in a series of studies, what effect the elements of CBT for tinnitus have on tinnitus distress. Study 1: The objective of study 1 is to examine the effects of audiological assessment, psychological assessment and a…
To examine whether compromised cochlear microphonic (CM) response during cochlear implant surgery results in poorer acoustic hearing preservation compared to preserved CM.
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…
The primary aim of this study is to develop ecologically valid listening tests with realistic social consequences of speech understanding difficulties in which physiological outcome measures are applied. Specifically, we aim to develop a speech…
