A multi-band environment-adaptive approach to noise suppression for cochlear implants
Forough Saki, Taher S. Mirzahasanloo, Nasser Kehtarnavaz · 2014
This paper presents an improved environment-adaptive noise suppression solution for the cochlear implants speech processing pipeline. This improvement is achieved by using a multi-band data-driven approach in place of a previously developed single-band data-driven approach. Seven commonly encountered noisy environments of street, car, restaurant, mall, bus, pub and train are considered to quantify the improvement. The results obtained indicate about 10% improvement in speech quality measures.
