Control of feedback in hearing aids - A robust filter design approach Academic Article uri icon

abstract

  • A bound on the variability of the feedback path is employed in the design of fixed FIR hearing aid filters that are robust to the specified variability, thus avoiding instability and howling in everyday use. A design example is presented for a linear gain hearing aid filter with a given maximal mismatch of the feedback cancellation filter.
