Hi there. I´m new here. I will soon introduce myself with a post in the welcome forum, but before that, I wanted to reply to this topic or else I will forget.
You claim yo have some sort of PTSD triggering by high pitched sounds, and also by noisy PCs that don´t let you concentrate. So, my question is: would it be possible that you also suffer from mild hyperacusis? I just ask because I have both conditions, which are probably related.
Most people are not even familiarized with condition, even the term. If that´s your case, there are tons of info in internet - not all accurate (it´s a very sneaky condition, just like eystrain). You can see if any of this rings a bell: https://hyperacusis.net/what-is-hyperacusis/4-types-of-sound-sensitivity/
