I had lots of ear infections as a kid, and in my teens developed a habit for popping my ears by plugging my nose and blowing. I am pretty sure that is how I ended up with Tinnitus (a constant ringing in the ears)... Its really a pain for me because I am most sensitive to sensory overload based on sound.
However, I don't believe that my hearing is significantly impaired. Last hearing test I took I did fine, and I used to do my own audio engineering (just wasn't good with noise reduction :p)
