I was already well-established in my career when my hearing and balance problems began. In fact, I was 38 years old and in the middle of my PhD program. So, I didn't have your same problem. However, what I would recommend you do is to try out some of the stethescopes for people with hearing impairments to find the one that works best for you. It will probably cost a lot of money, but it may be worth it. Also, be sure to speak up and let people such as your teachers, classmates, and colleagues know if you are having trouble hearing. Patient safety is always more important than your ego or your professional insecurities. Don't let any insecurities on your part prevent you from getting the assessment data you need.

Good luck to you!
