“And it’s not impossible that infrasound could explain some of what diplomats thought they heard.

Cuba mystery: What theories US investigators are pursuing
WASHINGTON — There must be an answer.
Whatever is harming U.S. diplomats in Havana, it’s eluded the doctors, scientists and intelligence analysts scouring for answers. Investigators have chased many theories, including a sonic attack, electromagnetic weapon or flawed spying device.
Each explanation seems to fit parts of what’s happened, conflicting with others.
