I'd like if I may to discuss the issue of hearing new tinnitus tones that
suddenly appear. I've had t for 15 years now. It's always been the hissy
type and despite the fact that it fluctuates in volume, the actual tinnitus
sound itself never varies and consequently I've largely become accustomed to
it. A couple of days ago I started to hear a pure tone as well as my normal
hiss. On my guitar it's pitched at a 'B' note and it's fairly constant. Very
annoying actually and this is much harder to deal with. Today it's just the
same, but oddly the noise seems to fluctuate and certain things make it
louder like being around computers. This is quite sad as my job means I'm
round computers all day.

My question really is, have any of you guys experienced actual changes in
your tinnitus sound? Have the changes been permanent and if not, how long
have they lasted?? Has there been a trigger that caused the change??

Thanks for your help

Dave
