Source Separation for Feedback Cancellation in Hearing Aids
This thesis addresses the problem of feedback cancellation in hearing aids using source separation techniques. Feedback oscillation (when a hearing aid whistles) is a major issue with hearing aids. It limits the maximum gain that can be achieved. The biggest barrier in solving this problem is the bias in feedback cancellation. A great number of algorithms are proposed during the last two decade...
متن کاملImproved prediction error filters for adaptive feedback cancellation in hearing aids
Acoustic feedback is a well-known problem in hearing aids, caused by the undesired acoustic coupling between the hearing aid loudspeaker and microphone. Acoustic feedback produces annoying howling sounds and limits the maximum achievable hearing aid amplification. This paper is focused on adaptive feedback cancellation (AFC) where the goal is to adaptively model the acoustic feedback path and e...
متن کاملCombination of Adaptive Feedback Cancellation and Binaural Adaptive Filtering in Hearing Aids
We study a system combining adaptive feedback cancellation and adaptive filtering connecting inputs from both ears for signal enhancement in hearing aids. For the first time, such a binaural system is analyzed in terms of system stability, convergence of the algorithms, and possible interaction effects. As major outcomes of this study, a new stability condition adapted to the considered binaura...
متن کاملAuditory Perception and Verbal Intelligibility in Children with Cochlear Implant, Hearing Aids and Normal Hearing
Objective: The aim of the present research was to compare the auditory perception and verbal intelligibility in children with cochlear implant, hearing aids and normal hearing. Methods: 60 children aged 5-7 years were divided to three groups and each group contained 20 children. The first and second groups were selected ordinarily from children with cochlear implant and hearing aids by conve...
متن کاملBand-limited feedback cancellation with a modified filtered-X LMS algorithm for hearing aids
Commonly used wideband adaptive feedback cancellation techniques do not provide satisfactory performance for reducing feedback oscillation in hearing aids. In this paper, a band-limited adaptive feedback cancellation algorithm using normalized filtered-X LMS techniques is proposed that provides good cancellation efficiency, convergence behavior and better output sound quality for speech signals...
