Latest Patents

One of Hsiang-Feg Chi's latest patents is the "Band-limited adaptive feedback canceller for hearing aids." This innovative method enhances the adaptive cancellation of acoustic feedback in hearing aids and other audio amplification devices. The feedback cancellation is confined to a frequency band that includes all unstable frequencies. By restricting the bandwidth of the feedback cancellation signal, the distortion caused by the adaptive filter is minimized, affecting only the unstable feedback regions. A relatively simple signal processing algorithm is employed to achieve highly effective results with minimal signal distortion.
