I cannot remember not having tinnitus...low cricket chirping. For the longest time, I really thought I was really hearing crickets, and kind of enjoyed it...sitting on the back porch. It became part of me, and although I hear it all the time, it does not bother me. While I was in recovery from surgery, I got the static sounds like you, and thought if this was going to continue like this, it would drive me crazy. It went away in about two days and now I'm back to the crickets. You can only hope it is part of the recovery, and it will go away soon. If it does not go away, and since it is brand new to you, it will be hard to live with for a while. If I am around noise...tv, radio, back ground noise, I don't hear those crickets, but dead silence brings them out. Turn on some music and see if that helps mask the sound. Good luck to you.
