Electro-Tactile Stimulation Enhances Cochlear Implant Speech Recognition in Noise

Abstract For cochlear implant users, combined electro-acoustic stimulation (EAS) significantly improves the performance. However, there are many more users who do not have any functional residual acoustic hearing at low frequencies. Because tactile sensation also operates in the same low frequencies...
