I just started a CAN school this past weekend. I am 100% deaf in my one ear and have a hearing lose of 50-60% in the other ear. I told my two teachers about it and asked if I could please use my electronic stethoscope with Ambient Noise Reduction. She told me that I could not use because I would not be able to use it when I take boards. The school gave us nice stethoscopes to have, so I used it and can somewhat hear out of it. I then had to use the Dual Head Teaching stethoscope in skills lab and could not hear ANY thing out of it. Does anyone know what I can do? Any help is needed as I take boards in six weeks. Thanks:)
