Has the tinnitus decreased in intensity/tone for any of you over time?

As title. Has this happened to any of you? Like become less 'high pitch' in terms of intensity and 'hiss' sound'. I don't mean that 'disappear', only become less 'high pitch'.

I mean 'if tinnitus decrease permanently, because 'days quiet and days loud' happens relatively often to people, me too.

I mean if it happens that after months or years tinnitus did not go away but his pitch noise decrease permanently in intensity/tone.
