Evaluate the performance of directional microphone systems in binaural (bimodal or bilateral) cochlear implant users
To investigate hearing improvement following day-case stapes surgery compared to in-patient stapes surgery and the effect of both methods on quality of life, cost-effectiveness and complication rates (mainly tinnitus and vertigo).
To investigate the cost-effectiveness of day-case cochlear implantation compared to inpatient cochlear implantation and the effect of both methods on quality of life.
Primairy objective:To compare the incidence of inflammation between the test group (MIPS technique using an Oticon Medical Ponto abutment and implant) and control group ( Hultcrantz technique using an Oticon Medical Ponto abutment and implant) after…
Primary research questions:1. Does tinnitusspecific- behavioural exposure-treatment (T-BET) decrease tinnitus-related fear, tinnitus-severity and enhance recovery, when compared to a masking-therapy with use of personalised on-ear masking-devices,…
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.
This research will explore how fast phonemic restoration of degraded speech can be learned. This will be done by training and testing normal-hearing listeners in several sessions with interrupted speech. We will also train a group of normal-hearing…
The objective of this study is to develop and test a DSL-protocol which will focus on proper use of hearing-aids, and will also provide patients (and their significant others) with specific skills to improve the use of the senses and communication.…
To evaluate the effectiveness of bilateral implantation over unilateral implantation in children with severe-to-profound sensorineural hearing loss. Furthermore with this study we will investigate whether simultaneous bilateral implantation is…
The objective of the study is to answer the following questions:a) Does the PLS-strategy improve pitch- and speech-perception?b) How does the number of harmonics in consecutive channels influence frequency discrimination, in speech coding strategies…
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…
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…
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 1 year follow-up.…
(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 measure the gap detection threshold in CI users and (NH control subjects) considering the effect with speech-like stimuli using direct stimulation or CI device.
The primary objective of this study is to evaluate the effectiveness of two differently sized pistons used in primary stapedotomy for otosclerosis in terms of hearing improvement, complication rate and general and disease-specific quality of life.
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..
Primary objectives are to measure how phonemic restoration changes as a function of 1. the inherent bottom-up cues that come from the speech signal (spectral information, pitch contours, fundamental frequency, temporal envelope, etc), and 2. the…
Evaluation of the effect of treatment with the Meniett in patients with unstable Menière*s disease.
Primary Objective: To show superiority of the novel fixtures compared to standard fixtures regarding stability of the implants measured as ISQ values.Secondary Objectives: 1. To compare the long time survival of the standard fixtures and abutments…
