I've been reading quite a number of posts from other people on this forum. One thing I notice is that people who have T on one side, myself included, have it in the right ear. For me myself, before T started, I've always talked on the phone using my right ear. I've read up somewhere that our left ear picks up more of the lower frequency sounds, which include our voices. This is something I came up with, but i have no scientific proof of. It is interesting though, thinking about it.
