If they were able to, the author wouldn't have written this article, or would've added it at least.

Tinnitus is a challenging problem because there can be physical causes (like hearing damage from loud music) but there's also a brain component. Certain diseases like MS, concussions, or some types of brain diseases can cause it even if your hearing organs are perfectly fine.

It's possible the author has had damaged hearing from a very young age but based on the wide variety of sounds they're describing, I'm guessing there's more going on than just ear issues. It's possible that these noises are just strange hallucinations of the auditory cortex, like someone hearing voices or sounds that aren't there but expressed less concretely.

As anecdata: an acquaintance of mine was cured of his tinnitus when he got therapy and made life changes to benefit his mental health. It turned out stress and other such problems were causing his hearing issues all along!

As far as I know, there is no known cure to tinnitus as bad as this article describes. In some cases the problematic symptoms can be reduced (people sleeping with a fan on or some white noise generator running to reduce the ringing of the ears is a common example) but the symptoms often come back soon after turning off the noise.
