The objectives are to evaluate the degree of bilateral benefit gained from having a second implant with respect to speech perception, spatial hearing, and listening effort.
The main goal of the study is to characterize the perception of vocal characteristics through a cochlear implant. It will span a number of aspects: psychophysical characterisation, its relation to speaker discrimination, its relation to single voice…
The primary objective of this study is to demonstrate that free field word recognition scores in quiet and noise with CI *ON* are significantly better than the best aided pre-implant scores in the ear to be implanted (contralateral ear plugged)…
Primary Objective: Investigate whether early valganciclovir treatment of children with SNHL of * 20 dB, unilateral or bilateral, and a confirmed congenital CMV infection can prevent deterioration of the hearing loss at follow-up (age 18 * 22 months…
The aim of this study is to validate known, and identify novel allelic variants which may play a role in the risk of cisplatin-induced ototoxicity in a substantial international cohort of children diagnosed with cancer.
The purpose of this study is to investigate the prevalence of hearing impairment amongst dentists who are working in the Netherlands.
The first sub-project (part 1) aims to identify and characterize realistic dynamic scenarios in which speech communication takes place. In the second sub-project (part 2) we will investigate speech recognition performance in those realistic dynamic…
The general goal of our study is to unravel the anatomical and functional correlates of tinnitus in the human brain using structural and functional magnetic resonance imaging (MRI). We will use a high-field (7 T) MRI scanner and obtain a) detailed…
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 (…
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…
The purpose of this study is the validity and applicability of an objective internet screening test appropriate for the detection of occupational noise-induced hearing loss, that can be performed in a remote setting (at home or at work).
The proposed studies will investigate the effect of auditory attention on speech comprehension, its relation to listening effort, and the effect of hearing loss on these processes.
1. To implant a functional vestibular prosthesis using the ampullar *V*-approach, as developed in our own clinic.2. To investigate protocols for adjusting the vestibular implant (VI) to required settings, regarding:-- Modulation sensitivity--…
Aim1. To investigate the long-term effects of early detection and intervention of hearing loss on the development of children with congenital bilateral hearing impairment. 2. To define factors in early childhood that are able to predict…
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…
The current study employs functional magnetic resonance imaging (fMRI) to investigate the relation between peripheral hearing loss, tinnitus and cortical reorganization. In particular, it aims to map the topographic representation of sound frequency…
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).…
To measure detection thresholds, loudness, and melody perception in CI recipients in order to assess extent of nerve degeneration between good and poor performers with respect to speech perception.
