Digital Signal Processing for Hearing Instruments

  1. Content type: Research Article

    In contemporary cochlear implant systems, the audio signal is decomposed into different frequency bands, each assigned to one electrode. Thus, pitch perception is limited by the number of physical electrodes i...
