Digital Signal Processing Algorithms for Noise Reduction, Dynamic Range Compression, and Feedback Cancellation in Hearing Aids KU Leuven
contain signal processing algorithms for noise reduction, feedback
suppression,... Most hearing aid users have hearing aids at both ears
in a so-called bilateral configuration, which means the hearing aids
The independent processing of the bilateral configuration destroys the
so-called binaural cues (the time and level ...
Current clinical practice requires active cooperation of the patient to individually fit a hearing device. The most important parameters for this fitting process are related to loudness. The aim of this PhD was to find neural correlates of loudness using 40-Hz auditory steady-state responses. These responses are auditory evoked potentials that can be measured fully objectively, non-invasively, and frequency-specifically in the ...
The healthy human auditory system is able to attend to a particular speaker of interest in a multi-speaker scenario. Current hearing aids, however, cannot sufficiently mimic this ability, possibly leading to far-reaching consequences for hearing impaired people, such as social isolation. For effective noise suppression and correct speaker amplification, it is crucial to detect which speaker of multiple speakers should be attended to. By ...
Hearing-aid users often make statements such as ‘I can hear you, but I can’t understand you!’ These statements indicate that the listener has a near-normal ability to detect sounds (I can hear you) but is suffering from degradation in the acuity of their hearing (I can’t understand you!). Fitting a modern hearing aid involves adjusting the device based on feedback; either via the user indicating the quietest sound they can detect at different ...
ACT now!: Auditory Cognitive Testing to optimize hearing aid benefit Ghent University
The goal of the current research proposal is to optimize hearing aid benefit taking into account the interaction between auditory periphery and more high-order cognitive functioning. It is focused on first, hearing outcome measures leading to insights with regard to speech understanding and listening effort, and second, the fitting and users of hearing aids leading to evidence-based
