While it is possible that this whole incident was due to some sort of shared hysteria, I don't think one can elevate that to the most plausible explanation for a few reasons: 1. This has a national security and counterintelligence aspect to it. For that reason, there may be evidence that proves the source and nature of the attack(s) that is classified. 2. This article keeps going back to 'it's impossible for an acoustic device to cause brain damage'. This assertion is coming from a guy who doesn't seem to be an expert on that particular subject. And just because he is not aware of such a thing, doesn't mean "it's impossible'. 3. A lot of focus is on the very specific language of an 'acoustic attack' but the incident could have been caused by microwave radiation. Indeed in the 60's US intelligence has uncovered Russian listening devices that were activated remotely with microwaves. Back then, they could find no definitive link to any cognitive degradation but who knows what technology may be in play today. http://foreignpolicy.com/2017/08/25/the-secret-history-of-diplomats-and-invisible-weapons-russia-cuba/ http://foreignpolicy.com/2017/08/25/the-secret-history-of-di... There was another story about a similar incident involving 2 NSA employees who were deployed to a clandestine location who experienced nervous system disease afterwards. https://www.washingtonpost.com/local/was-a-spys-parkinsons-disease-caused-by-a-secret-microwave-weapon-attack/2017/11/26/d5d530e0-c3f5-11e7-afe9-4f60b5a6c4a0_story.html?utm_term=.7ab6e079f8ea https://www.washingtonpost.com/local/was-a-spys-parkinsons-d... Maybe these were all imagined incidents or something else is at play but I wouldn't dismiss it as hysteria out of hand, given what is publicly known.
