  • Cochlear implant pitch intensity
    Patent number: 7979135
    Abstract: A system and method are described for generating electrode stimulation signals for an implanted electrode array having multiple stimulation electrodes. An acoustic audio signal is processed to determine associated pitch characteristics and frequency component information. From the pitch characteristics and the frequency component information, electrode stimulation signals are determined which have intensity levels that reflect the pitch characteristics. Then audio nerve tissue is stimulated by applying the electrode stimulation signals to the electrodes in the implanted electrode array.
    Type: Grant
    Filed: July 3, 2008
    Date of Patent: July 12, 2011
    Assignee: MED-EL Elektromedizinische Geraete GmbH
    Inventors: Christoph Arnoldner, Jafar Sasan Hamzavi
