Title

ACOUSTIC FEEDBACK SUPPRESSION IN BINAURAL HEARING AIDS

Pages

  207-214

Abstract

 Background and Aim: The hearing loss and ACOUSTIC FEEDBACK signal in the binaural HEARING AIDS may annoy users, make speech reorgani-zation difficult, and affect the sound quality. This paper presents a new method for ACOUSTIC FEEDBACK suppression in binaural HEARING AIDS, based on the combination of binaural informa-tion and blind SOURCE SEPARATION. This method can enhance sound from the specific direction of the user and cancels ACOUSTIC FEEDBACK signal so that the user can hear clearly.Methods: In the proposed method, the binaural information (interaural time differences (ITDs) and interaural level differences (ILDs)) was generated using COMPUTATIONAL AUDITORY SCENE ANALYSIS (CASA). In addition, we used underde-termined blind SOURCE SEPARATION (BSS) for the automatic classification of the time-frequency (T-F) units of the speech mixture spectrogram. The system performance was evaluated using 32 acoustic English speech mixtures. The sound quality was assessed using 19 normal-hearing listeners of both genders.Results: The system achieved a good ACOUSTIC FEEDBACK suppression performance by giving a higher signal to noise ratio and 18.07 dB on average for the signal-to-feedback ratio. In addition, the sound after processing had a high quality according to the subjective assessment.Conclusion: Our system allowed the user to increase the gain of the hearing aid without affecting the sound quality.
