The fundamental challenges facing our world is around five percentage of world’s population is suffered from hearing issues. A person with hearing issues faces difficulties to hear in unfavourable listening environment. Mostly analog and digital hearing aids solves these problems. Digital hearing aids performance is good than that of analog. That is digital noise reduction techniques gives better result than analog. Mainly adaptive filter and wiener filter algorithms are used as noise reduction algorithms. In this work, compare both adaptive and Wiener filter algorithms in static and dynamic noise environments and introduce a new algorithm, i.e., better in dynamic environment. |
