US State department in China reports ‘abnormal' sound like diplomats heard in Cuba

The State Department has said a US government employee in China reported “subtle...but abnormal” ear pressure, possibly pointing to a similar situation experienced by American diplomats in Cuba. The agency emailed a notice to all US citizens in China about the employee at the consulate in Guangzhou who said there were “subtle and vague, but abnormal, sensations of sound and pressure”. It advised Americans to contact medical professionals if they experience any “unusual auditory or sensory of phenomena accompanied by unusual sounds or piercing noises”.
