Happy anniversary to !
I understand your feeling. The untreated sound in some vbs can be painful to listen too due to excessive fundamental tone or excessive sizzling sounds, very tiring to listen, these can easily trigger tinnitus. I'm prone to 600hz to 2khz these frequency sound offended to me.I don’t have much of a technical opinion on it but I can offer my own experience I am deaf in my right ear with very limited hearing abilities (like none) but with Cevios old engine noise it used to flare my tinnitus terribly for a few days after like around 10 mins of listening to cevio covers where it wasn’t edited out lol, also had the issue less so with every other vocal synth but not as bad e.e I think it’s more so a frequencies thing for me? Like I can’t recall anything aside from a metallic twang in my good ear but my bad one tries to shut down :x
