Both my former hearing aid audi and current CI audi have a doctorate in Audiology. My former CI audi had a Master's, but went on to earn her doctorate last year. That being said, what I think is more important than one's degree is the relationship you have with your audi. Even though my former CI audi only had a Master's at the time I worked with her, it didn't mean she was any less effective or helpful than my current CI audi.
