Iir filters in hearing aids
WebHearing instruments employ filter bank systems (FBS) to subdivide the microphone signal into subband signals. To reduce overall computation, decimation is applied, which inevitably induces disturbance. First, these effects are analysed in detail. Then, we postulate application specific FBS requirements in view of extensive subband signal amplification. … Web22 uur geleden · April 13, 2024 expert reaction to observational study looking at hearing aid use and risk of dementia .
