Is it normal for tinnitus to have the same sounds that come and go ?

So I get the same sounds that come and go alot. Sometimes it's a howling wind storm with wine glass humming or tuning forks in the distance and sometimes its bells and chimes and cricket noises. The worst sounds I get are piercing high pitch whistles that feel like they are hurting my brain and very loud booming truck engine noise or the loud ooooo ooooo wavering noise will often transform into a booming truck engine but the truck noise and loud whistle hasnt happened often except 2 days ago. I guess I'm worried these will all become my sounds some day and turn into my baseline. I get like the same soundtracks of tinnitus so one week it could a tuning fork wind storm, the next week cricket and bell sounds then the week after it's high pitch whistles. These all come in different volumes but the low frequency tinnitus is often the loudest that vibrates my head. I use to have a very faint whistle sound before all this 5 months ago.
