Welcome to the Cochlear Implant (CI) Theory Site  




It's hosted by Mike Marzalek, a retired Hewlett Packard/Agilent engineer, and Adjunct professor

at Arizona State University.


I have a CI and have been using it to work on a next generation CI speech & music strategy.




Here you will find:

        How to optimize your CI performance CI_Optimize

        My biography & and background

        Information about my speech processor & work

        Overview of Hearing Loss, Hearing Aids, and Cochlear Implants

        Downloads like a CI calibrator & a virtual piano that I developed to help me MAP my CI

        Two CT images showing my electrode placement: First and Second.




I hope you enjoy it!
