Iir filters in hearing aids
Web1 sep. 2015 · Hearing aids require a bank of filters to suitably adjust the gain characteristics in the required band of frequency. Digital filter banks decompose the input signal into different frequency regions. This facilitates to give appropriate gain to specific frequencies. As a result efficient designs for digital hearing aid can be achieved. Web28 jun. 2024 · The main aim of the hearing aid is to decrease the noise signal from the desired sound signal. An algorithm is needed for avoiding the effects of noise. Several …
