ORL Department of Neurosciences Katholieke Universiteit Leuven O N Herestraat 49 bus 721 3000 Leuven Belgium Email Digital signal processing for hearing aids was initiated as a topic of research in the mid-late 1980s. However it was not until 1995 that the technology matured to a level where small-size and low-power consumption allowed the market introduction of hearing aids with full digital signal processing capabilities. Today 83 of hearing aids sold worldwide are digital. Advanced packaging technologies enable hearing aids that fit completely in the ear canal and the introduction of truly programmable platforms has allowed the development of advanced digital signal processing algorithms that provide the hearing-impaired user a natural sound picture with increased speech intelligibility and comfort. Modern cochlear implant systems are capable of far more advanced processing than before. Whereas cochlear implants adopted digital technology prior to hearing aids it is only until very recently that they have integrated some specialized algorithms such as adaptive noise reduction. A cochlear implant needs in addition a speech processing strategy that converts the acoustical signal into electrical signals to be applied to the electrodes placed in the cochlea. The design of such sound .
