Video: How do sound waves cause brain damage to US diplomats?

US and Canadian diplomats in Havana, Cuba, are diagnosed with brain injury due to sound weapons attacks on where they live.

Sound waves cause diplomats to lose their hearing and vomit to balance disorders.

Some diplomats have to end their working time in Cuba early due to attacks beginning in mid-November 2016 and ending this spring, according to CNN. Diplomats exhibit many symptoms from hearing loss and vomiting to balance disorders. The cause is said to be due to sound weapons operating outside the threshold of human hearing located in or out of the diplomatic residence in Havana.
