There was an article published awhile back that seemed to indicate the noises people heard (and still here) are due to tinatus and speculated they were poisoned with one of the many prescription medications that can cause tinatus. I can’t remember if they had any clinical testing but it seems a lot more plausible than some kind of sonic attack. As someone who recently started suffering from mild tinatus I can assure you it’s a very bizarre sensation. If I didn’t know better I’d assume I was the victim of some kind of attack on my hearing as well.
