Hi! I'm not an audiologist yet, hoping to start Fall 2015. Yes, audiologists do deal with balance and hearing issues, not all deal with balance, it just depends on where you work at. There is a wide range of jobs available to audiologists in the US.
Average starting salaries for audiologists range from 50k-60k. I do think that salary, on its own, is certainly enough to live comfortably on, depending on where you live. I live in the midwest, so 55k means more here than in a bigger area like California where cost of living is much higher (salaries are there also, but still). If my husband and I both made that much, I do think that would be MORE than enough to live comfortably.
However, a truth is that audiology programs cost a LOT OF MONEY. Average, students can sometimes expect to take out around 100K in loans, which is a lot considering low-end starting salaries are 50k. The money is decent, but you really do need to have a passion for the field. There are many other programs that are cheaper that have similar or greater pay, such as SLP, Physician's assistant, etc. Also, try and find a school that will offer in-state tuition or try your best to get a graduate assistantship to work in school, as that can dramatically bring down costs. Knowing this, I'm still going full steam ahead to work as an audiologist and I feel that the money will be good enough for me 🙂 Again, not an audiologist yet but feel free to ask any more questions and I can try and help out if I can!
