Abstract
A hearing signal processor processes an input sound signal and generates an electrical communications signal for an upper range of sound frequencies, and an acoustic communications signal for a lower range of sound frequencies. An implanted electrical stimulation subsystem includes an electrode array with one or more electrode contacts in an acoustically perceivable cochlear region retaining residual natural hearing. The electrical stimulation subsystem receives the electrical communications signal and delivers corresponding electrical stimulation signals to the electrode contacts for electrical stimulation of adjacent neural tissue. An external acoustic stimulation subsystem receives the acoustic communications signal and delivers corresponding amplified acoustic stimulation signals to the ear canal of the patient. The upper range and the lower range overlap and the electrical stimulation signals and the amplified acoustic stimulation signals are coordinated for simultaneous delivery to the acoustically perceivable cochlear region.
