Do You Know Any Good (Non-Tonal) Tinnitus Matching Sites?

There's plenty of good sites for tonal T which I can match my tones to, but I also have tone a that I can't place, it's not a pure tone, but it's not like a standard hiss or white noise or the likes either.

It's "almost" a pure tone, but it's not.

I try to focus on it to try to match it to something but I can't think of anything or find anything that is like it.

In my mind, it makes me think of a radiator, even though it doesn't sound like one, which is weird! Maybe I have some subconscious memory of a broken radiator making a similar noise before.

Does anyone know of any good tone generator sites where non-tonal T can be matched? Thanks all!
