I'm a second year AuD student at Ohio University, and my perspective is that audiology is more than hearing, it definitely also involves balance testing, measuring brainwaves on folks who can't talk to you, and other stuff. If you're into that, hearing aids, etc. you might give an AuD a try. It's a big time and money commitment if you're not passionate about it-I have no regrets and love what I do, but your mileage may vary.
