With a cochlear implant deaf people are able to recognize speech and acoustic signals. Problems occur in adverse conditions, e.g. in reverberant and/or noisy environments. Experiments were carried out to improve the intelligibility of noisy speech using a modified spectral subtraction technique. This was realized as a kind of preprocessing by applying the resynthesized speech signal to the cochlea implant system. Intelligibility tests were done in collaboration with the clinical hospital in Aachen.
