‘Sonic attacks’ in Havana may have been crickets chirping

In August, American and Canadian diplomats working in Havana reported hearing sounds that were believed to be a mysterious sonic weapon.

Doctors termed the sounds ‘directional acoustic phenomena’, and even noticed brain changes in those hearing it.

But Cuban scientists insist that a sonic weapon was not to blame.

Instead, they suggest that the sound was produced by the stress of listening to ‘noisy crickets’ in Havana.

WERE CRICKETS TO BLAME? 

Researchers recorded evening sounds around the US and Canadian embassy residences, according to Science

The recordings revealed that the biggest noisemakers were insects. 

In particular, the researchers found that the Jamaican field cricket chirps at a frequency matching the sound on the recordings, which topped out at 74.6 decibels.   

But doctors still don’t know how victims ended up with the white matter changes, nor how exactly those changes might relate to their symptoms. 

A report issued by a board of Cuban scientists suggests that crickets are the unlikely culprits of the brain-changing sounds. 

While US officials did not provide sound recordings to the scientists, Carlos Barcelo Perez, an environmental physicist at the National Institute of Hygiene, Epidemiology and Microbiology, recorded evening sounds around the residences, according to Science

The recordings revealed that the biggest noisemakers were insects. 

In particular, he found that the Jamaican field cricket chirps at a frequency matching the sound on the recordings, which topped out at 74.6 decibels.   

It follows news yesterday that medical experts have discovered changes in the brains of US and Canadian diplomats, which fuelled growing scepticism that some kind of sonic weapon was involved.

Medical testing revealed the embassy workers developed changes to the white matter tracts. 

These regions act like information highways between brain cells letting different parts of the brain communicate. 

Speaking to DailyMail.com, Dr Joel Moskowitz, a community health professor at the University of California, Berkeley, said: ‘This makes me think the victims may have developed electromagnetic hypersensitivity (EHS) from exposure to electromagnetic fields in the embassy.

BRAIN CHANGES 

Yesterday, medical experts discovered changes in the brains of US and Canadian diplomats, which fuelled growing scepticism that some kind of sonic weapon was involved. 

Medical testing revealed the embassy workers developed changes to the white matter tracts, which acts like information highways between brain cells letting different parts of the brain communicate. 

Doctors still don’t know how victims ended up with the white matter changes, nor how exactly those changes might relate to their symptoms. 

‘This happened during the Cold War to personnel stationed in the US embassy in Moscow when the Soviets were bombarding the embassy with microwaves to monitor oral communications in the ambassador’s office.’

Loud, mysterious sounds followed by hearing loss and ear-ringing had led investigators to suspect ‘sonic attacks.’ 

But the new report suggests that the ‘sonic attacks’ were really just crickets. 

Doctors still don’t know how victims ended up with the white matter changes, nor how exactly those changes might relate to their symptoms.

The Cuban scientists also evaluated other possible causes of the brain changes, such as permethrin – an aerial fumigant used to kill mosquitoes that is known to cause nausea, headaches and shortness of breath.

But the Cuban team found no evidence of excessive use of the fumigant. 

Antonio Paz Cordovéz, president of the Cuban Society of Otorhinolaryngology, said: ‘We have devoted months to this work, but we have not found any evidence that could substantiate [the US] claims.’  

The FBI is now planning its own investigation, to confirm whether or not crickets were causing the sounds.
