As one of the many things I dwell on about T, that fact it cycles drives me nuts. I saw anew audiologist recently and I did like him, plus he told he had T for 2 years and now he no longer hears it so I was prepared to listen to him. But he says it is impossible for T to change from day to day. Mine honestly changes minute by minute some days. But it has a pattern, one day is louder to start and goes up all day, the next is very quiet to start and only develops to very high hiss, then the cycle repeats. The audiologist says it me doing it, but I had two breaks away recently where life was noisy chaos, sleep disruption and it seemed to alter but once back home within a day it had slipped back to its old routine. Does anybody else have a clear pattern?
