Cuba sonic attacks

Who is behind these attacks and why?   And what is the technology involved, what is the nature of the weapon(s)? Is there a way to counter it? [and from another] https://www.theguardian.com/world/2017/sep/14/mystery-of-sonic-weapon-attacks-at-us-embassy-in-cuba-deepens Soon came the hearing loss, and the speech problems, symptoms both similar and altogether different from others among at least 21 US victims in an astonishing international mystery still unfolding in Cuba. At least some of the incidents were confined to specific rooms or even parts of rooms with laser-like specificity, baffling US officials who say the facts and the physics don’t add up. The diagnosis of mild brain injury, considered unlikely to result from sound, has confounded the FBI, the state department and US intelligence agencies involved in the investigation. Some victims now have problems concentrating or recalling specific words. Aside from their homes, officials said Americans were attacked in at least one hotel. The cases vary deeply: different symptoms, different recollections of what happened. Some felt vibrations, and heard sounds – loud ringing or a high-pitch chirping similar to crickets or cicadas. Others heard the grinding noise. Some victims awoke with ringing in their ears and fumbled for their alarm clocks, only to discover the ringing stopped when they moved away from their beds. The attacks seemed to come at night. Several victims reported they came in minute-long bursts. Other symptoms have included brain swelling, dizziness, nausea, severe headaches, balance problems and tinnitus, or prolonged ringing in the ears. [and from another] http://www.cbc.ca/news/politics/cuba-sonic-sound-attacks-canadian-diplomats-1.4289996 Some reported the sounds and sensations could only be felt in certain parts of the house, and that they could walk in and out of the affected area, feeling the effects shut off as they moved away from it, and resume as they moved back in. [and from another] http://hosted.ap.org/dynamic/stories/C/CB_CUBA_ATTACKS_CASTROS_DENIAL?SITE=AP&SECTION=HOME&TEMPLATE=DEFAULT&CTIME=2017-09-15-12-29-50U.S. diplomats started reporting last November. Fidel Castro died on Nov. 25. State Department had to withdraw its assurance the attacks had long ceased. There had been another incident, on Aug. 21. [and from another] https://en.wikipedia.org/wiki/Microwave_burn Sensory nerves are particularly sensitive to microwave damage. Cases of persistent neuritis and compression neuropathy were reported after significant microwave exposures. A neuropathy due to peripheral nerve lesion, without visible external burns, can occur when the nerve is subjected to microwaves of sufficient power density. The damage mechanism is believed to be thermal. Radiofrequency waves and ultrasound can be used for temporary blocking of peripheral nerves during neurosurgical operations.  Dielectric heating (diathermy) is used in medicine; the frequencies used typically lie in the ultrasonic, shortwave, and microwave ranges. [and from another] https://en.wikipedia.org/wiki/Health_effects_from_noise#Infrasound_.28low-frequency_sound.29 Infrasound, sometimes referred to as low-frequency sound, is sound that is lower in frequency than 20 Hz (hertz) or cycles per second, the “normal” limit of human hearing. [and from another] http://elementmountain.com/den-post/elf-detailed-affects-upon-humans/ What exactly are the affects of ELF on the body. Extra Low Frequency also emits from household appliances, electricity lines in homes as well as major AC transmission lines and generating stations. Complaints are: memory blanking, ringing in the ears, sight issues, forgetfulness, confusion. 

Clearly a targeted attack from a portable weapon, in fact multiple weapons triangulated to focus on a pinpoint target. Low level sound waves are normally silent to humans, just as a high pitched dog whistle cannot be heard by humans. These weapons used sound on the low side but were still perceived by many of the victims. Concussive damage to the brain and inner ear did not occur – injury resulting from a blow to the head or extremely loud noise where bleeding or broken bones result. The weapons used in Cuba used ELF, Extra-Low Frequency technology, readily available from the US military who have experimented with ELF as a communication device. 

The Cuba weapon included more than sound. A microwave component was included that would destroy brain matter and nerves. Mircrowave is used in the medical field to temporarily stun nerves to reduce pain during surgery and in the veterinarian field to kill the brains of lab animals. Thus, these devices are also readily available. That these attacks emerged just after Castro died identifies the perpetrators as resentful over US and Canadian intrusion into Cuban affairs. This is not an attack by a country, but older revolutionaries, who are seeking to counter any attempts to take over their country. “Viva Revolucion Cubana”.
