"What no one disputes is that, beginning in late 2016 and continuing until August 2017, a total of 24 US diplomatic personnel stationed in Havana, Cuba, experienced audible or sensory phenomena emanating from a distinct direction. When they moved, the sensation disappeared or lessened. Some described pressure-like or vibratory stimuli akin to air “baffling” inside a moving car when a single window is partially rolled down. The stimuli lasted for as little as 20 seconds to as long as 30 minutes.
"The diplomats experienced the stimuli in their homes or hotel rooms, although family members and other hotel guests remained unaffected. Immediately or in the days and weeks after, the subjects reported an array of neurological impairments, including disorders of balance, sleep, vision, hearing or cognition. Headaches were also frequently reported." [1]
