According to this article at the University of Texas at Dallas News Center, the university's Cochlear Implant Lab has developed technology to do just that. Pending FDA approval, ten American healthcare and research facilities will begin to use it. The program will allow cochlear implant users to modify their settings depending on their environment - for example, in a loud restaurant or at a sports arena. They can even record sounds they are having difficulty with for later analysis at the lab.
Here is a video about the technology. Unfortunately, it is not captioned. It does illustrate the way the technology interacts with the phone and the cochlear implant.
