Abstract
An electric acoustic stimulation (EAS) hearing system includes a signal processor for processing an acoustic signal input to generate: i. an electrical communications signal representative of an upper electrical range of acoustic frequencies, and ii. an acoustic communications signal representative of a lower acoustic range of acoustic frequencies, the acoustic range including: (1) a lower subrange of acoustic frequencies perceivable by the patient with amplification, and (2) an upper subrange of acoustic frequencies not perceivable by the patient, wherein the signal processor uses frequency transposition to include the upper subrange in the lower subrange. An implanted electrical stimulation subsystem receives the electrical communications signal and delivers a corresponding electrical stimulation signal to auditory neural tissue of an implanted patient. An external acoustic stimulation subsystem receives the acoustic communications signal and delivers a corresponding amplified acoustic stimulation signal to the ear canal of the patient.
