Latest Patents

Hsiang Feg Chi holds a patent for a "Band-limited adaptive feedback canceller for hearing aids." This invention presents an improved method for adaptively cancelling acoustic feedback in hearing aids and other audio amplification devices. The feedback cancellation is limited to a frequency band that encompasses 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.
