No need to be sorry. In fact, back then I didn’t very understant. Someone, a 10 years old kid, put a airsoft in my right ear (without bullet fortunatly) and bang! I went deaf at this ear for three days. We went to the doctor and he said that my ear was traumatize and that it would be finish in two years. I started to notice some things. Water running was making my left ear drumming as well as my teacher who had to talk in a micro. Also, sometimes I was stopping to ear and was left with a high pitched sound. I know now that it was fleeting tinnitus (the drumming still persist) but yeah. 7 years later it became chronic tinnitus but I don’t know if it would had change many. Maybe I would still have tinnitus even without the trauma.
