A worker in US Embassy in China experienced 'abnormal' sounds and Brain Damage

amxcoder writes: A US citizen working at a US consulate located in Guangzhou, China has reported experiencing "abnormal" sounds (and pressures) for the past several months, starting in late 2017 until Apiril of 2018. Upon medical evaluation, the worker has been diagnosed with mild traumatic brain injury symptoms. The US Embassy is conducting an investigation into the issue, and is issuing warnings to all US citizens in China. The symptoms and several other similarities has drawn comparison to a similar event last year in a different US Embassy in Cuba. Officials can not link the two events together at this point, but the US State Department is working with Chinese authorities to investigate the issue further.
