Development and IC implementation of signal processing algorithms for a digital noise reduction hearing aid
The overall objectives of this research project pertain to the prevalent and serious problem of poor speech intelligibility experienced by hearing instrument (hearing aid) users in everyday noisy environments due to the poor signal-to-noise ratio (SNR, typically 13 dB SNR) of speech in such envir...
