Hearing aid application of feedback cancellation algorithm in frequency domain  

Jarng, Soon-Suck (Dept. of Electronics Engineering, Faculty of Electronics and Information Engineering)
Abstract
In this paper, the realization of a hearing aid adaptively cancelling feedback noise was considered. Conventional least mean square method in time domain was transformed into frequency domain in order to minimize computational burden. The adaptive filter algorithm was evaluated by Matlab (Matrix laboratory), and it was confirmed by CSR 8675 Bluetooth DSP IC (Digital Signal Processor Integrated Circuit) chip firmware realization. Some remote control features by a smart phone was added to the smart hearing aid for user interface easiness.
