This sounds like a horrible experience, i'm guessing that you might have had the same reaction, in the same time frame if you had been exposed to extremely loud sound at a rock concert or in combat or even trap shooting. Something was ready to pop. Tinnitus and hearing loss are the two most frequently diagnosed disabilities in veterans returning from combat zones. Sudden hearing loss has been experienced in other situations too. It happened to a friend of mine during a long distance flight. I strongly recommend that you connect with HLAA (The Hearing Loss Assn. of America). It's a terrific support group full of people with a variety of hearing loss experiences. It helps to be able to talk with others who understand what you're experiencing. Glad you are reaching out here in this discussion group. I wish you well.
