Real-time implementation of hearing aid with combined noise and acoustic feedback reduction based on smartphone

Abstract

The demonstration presents a real-time mockup of smartphone- based hearing aid with combined noise and acoustic feedback reduction. The designed reduction algorithm is based on spectral weighting approach which makes it very robust to rapid changes in feedback path either caused by displacement of the speaker/microphone or room acoustics. The aim of the demonstration is to show potential of the implemented solution especially for devices with unfixed speaker and microphone setup.
