Havana Syndrome could be caused by pulsed energy devices – US expert report

A US intelligence report by a panel of expert scientists has named pulsed electromagnetic energy and ultrasound as plausible causes for the mystery Havana Syndrome symptoms suffered by US diplomats and spies in recent years.

The report found that a group of cases could not be explained by health or environmental factors or by psychosomatic illness. It also said that devices exist with “modest energy requirements” which were concealable and could produce the observed symptoms and be effective over hundreds of meters or through walls.

The panel, established last year by the director of national security, Avril Haines, and the CIA director, William Burns, said the investigation was not tasked to identify a culprit, but in a statement accompanying the report, Haines and Burns said it would help sharpen the search for the origins of they mysterious ailments.

“We will stay at it, with continued rigor, for however long it takes,” they said.

    Both audio and radio frequency spectrum analysers are readily available, and have been for at least 30 years.

    3 inches of wire makes a good aerial for high power microwaves. A tin-foil hat makes quite a good Faraday cage.

    An app in your iPhone could probably sense acoustic stuff well beyond what your ears would sense. If not,
    a cheap piezo tweeter connected to an Arduino would be enough to indicate suspicious acoustic activity.

    If they can't find it, either they are not looking, or its not there.
