Band-limited feedback cancellation with a modified filtered-X LMS algorithm for hearing aids
نویسندگان
چکیده
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, when compared to the wideband approach. Convergence analysis and computer simulations illustrate the advantages of the proposed approach. 2002 Elsevier Science B.V. All rights reserved.

Analysis of Adaptive Filters in Feedback Cancellation for Sinusoidal Signals
Analysis of coupling effects in adaptive filters is presented for feedback cancellation systems in hearing aids. As the incoming signal, a sum of sinusoids in white noise is assumed in this paper. In the proposed scheme two LMS-type adaptive filters are used. The one is set for identifying the impulse response of the feedback path. The other is associated with frequency estimation. We propose a...
متن کاملMultichannel active noise control algorithms using inverse filters
1.0 Introduction For active noise control (ANC) systems, a common approach is to use adaptive FIR filters trained with the filtered-x LMS algorithm [1], for both feedforward systems and Internal Model Control (IMC) feedback systems, in monochannel or multichannel systems. Variations of the algorithm sometimes called the modified filtered-x LMS algorithm have been published [2], which can achiev...
متن کاملIntegrated feedback and noise reduction algorithm in digital hearing aids via oscillation detection
In this paper, an integrated feedback and noise reduction scheme in hearing aids is developed. The technique presented is based on the adaptive feedback cancellation (AFC) and general sidelobe canceller (GSC) with a band-limited adaptation method to better the convergence behavior of both AFC and GSC. The band pass pre-filter is applied to AFC and the band stop pre-filter is applied to GSC to i...
متن کاملGenetic algorithm for Echo cancelling
In this paper, echo cancellation is done using genetic algorithm (GA). The genetic algorithm is implemented by two kinds of crossovers; heuristic and microbial. A new procedure is proposed to estimate the coefficients of adaptive filters used in echo cancellation with combination of the GA with Least-Mean-Square (LMS) method. The results are compared for various values of LMS step size and diff...
متن کاملAdaptive feedback cancelling in subbands for hearing aids
In this paper a hearing aid concept with recruitment of loudness compensation and acoustic feedback cancellation is presented. Special consideration is given to the acoustic feedback canceler which uses only the available (e.g. speech) input signal for adaptation. In principle, the feedback canceler is adapted to the feedback path in the transform domain using a power-normalized least mean squa...
