10. •  Sound waves enter through the microphone. •  The sound processor converts the sound into a distinctive digital code. •  The electrically coded signal is transmitted across the skin through the headpiece to the internal portion of the device. •  The internal device delivers the sound to the electrodes. •  The electrodes stimulate the hearing nerve. •  The hearing nerve sends the signal to the brain for processing. How Does a Cochlear Implant Work?
11. •  Hearing Aids— acoustically amplify speech. •  Cochlear Implants— convert speech information into electrical signals. How is a Cochlear Implant Different From a Hearing Aid? • Hearing Aids—rely on the responsiveness of healthy, inner ear sensory cells. •  Cochlear Implants— bypass the inner ear sensory cells and stimulate the hearing nerve directly.

16. 1-channel 2-channel 4-channel 8-channel 16-channel Original Implant simulations by Arthur Boothroyd, based on the work of Robert Shannon. Total bandwidth is 0 to 6000 Hz, and channel boundaries are logarithmically spaced. All within-channel frequency resolution is removed. The amplitude envelope in each band is preserved but it is imposed on a band of noise. This band covers the same frequency range as the band of speech from which the envelope was extracted. This is not “what speech sounds like to an implant user”. The simulation does, however, give an impression of the intelligibility of speech with the kind of dramatic reduction of spectral information produced by a cochlear implant. For best effect, begin with 1-channel and progress toward the original.
