Hi, I was at a skeet shooting range six days ago, and I was wearing inadequate 17 decibel custom earplugs. I was standing about 5 meters away from someone shooting a shotgun. I only heard one shot, then left. I know 17 dB reduction is not enough, but does standing 5 meters away reduce some sound? After I left, I heard no ringing or anything, but my own voice sounded weird, like during a cold? My hearing was noticeably less sensitive, however, and I'm really worried that it screwed them up permanently. It's been six days, and there has been little improvement in my hearing. When it's quiet, I hear a very faint ringing in my right ear that sometimes dissapeares, as well as some faint white noise. I went to an ENT today and he prescribed me Merilson Eisai. Will it help? Should I take it? It's more for vertigo, but apparently it can improve blood circulation to the inner ear. Any help is strongly appreciated.
