Good luck boomer2 and bhoward422.
bhoward422, if your C&P exam for hearing is like the one I had, the exam will be conducted where you are in a sound proof booth wearing a headset on your ears and the examiner will be outside of the booth pressing a button which sends tone sounds of different frequencies to your headset. You will press a button whenever you hear a tone. The examiner will test one ear at a time. While in the soundproof booth, the examiner will also administer a speech discrimination test where the examiner will say different words and you repeat the words back to the examiner.
Prior to my exam, the examiner conducted an interview with me and asked about my noise exposure in the military and after the military. She asked about civilian recreational (hunting, music concerts, etc.) or occupational (civilian work) noise exposure. She also asked if I had any ringing in my ears. I responded "yes" and she asked if the ringing noise was constant and I responded "yes." She also asked how long I had the ringing in my ears and I responded "since I was in the military." The examiner also asked what my military occupational specialty (MOS) was in the military and I responded "field artillery." Your responses are important.
I was awarded 10% for hearing loss and 10% for tinnitus.
