Thanks for your answer. I don't consider myself an outgoing person, but I believe when having my own clients, I can easily feel comfortable and "myself". (I was a swimming instructor for a few years, and was really fine when I was with the kids, teaching.) The SLPs I did shadowing with were all extraverted, so it mare me wonder if I would have the right personality for that job.
After thinking about the shadowing done with an audiologist, I realized that most of it is either providing the test to people without hearing lost or selling hearing aids. But the part which interests me in audiology is the rehabilitation. But from what I saw, there aren't a lot of job offer for this field.
