Digital Signal Processing Algorithms for Noise Reduction, Dynamic Range Compression, and Feedback Cancellation in Hearing Aids KU Leuven
Signal processing algorithms for binaural 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
work independently.
The independent processing of the bilateral configuration destroys the
so-called binaural cues (the time and level ...

EEG-based Auditory Attention Decoding for neuro-steered hearing aids to improve speech understanding KU Leuven
People with hearing impairment often have difficulties understanding
speech in noisy environments, leading to social isolation and
generally decreased quality of life. Hearing aids and cochlear
implants partly solve this problem through signal processing
algorithms that enhance the target speaker and suppress other noise
sources. However, in a scenario where multiple speakers talk
simultaneously, a fundamental ...
Adapting cochlear implants and hearing aids to individual brains. KU Leuven
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 ...
Deep learning for EEG and audio processing in neuro-steered hearing aids KU Leuven
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 ...
Sound processing for cochlear implants and hearing aids KU Leuven
In collaboration with a specialized company, research is carried out on the sound effect for combined cochlear implants and also looks at the acoustic stimulation
ACT now!: Auditory Cognitive Testing to optimize hearing aid benefit Ghent University
The goal of the this research 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
recommendations.
Unified, individualised, and self−adapting sound processing for combined cochlear implant and hearing aid Stimulation. KU Leuven
Cochlear implants can restore the hearing of the deaf by electrically stimulating the auditory nerve. They are often combined with a hearing aid in the non−implanted ear. This is called bimodal stimulation. Speech perception in a noisy environment and sound source localisation is still poor with these devices. They are manually fitted to individual patients by an audiologist in a fairly rudimentary and time consuming way. We will improve this ...
