Robin O. Cleveland, engineer, professor of engineering at the University of Oxford:
“It is difficult to believe that people suffered brain damage because the sound would have to go directly to the brain tissue and following the same principle of the ultrasound equipment if there is air between the body and the sound, it can not pass through it”.
Seth Horowitz, neurologist, specialist in neurosciences and author of the book “The universal sense. How hearing modifies the mind “
“There is no acoustic phenomenon in the world that can cause the symptoms that have been described.” He explained that “no known equipment that is inaudible and undetectable could have the properties attributed to these sonic weapons”
“As long as there is no other evidence related to these weapons, this incident should be considered something of no interest and other possible explanations for these medical problems should be taken into account.”

“The ultrasound can not travel a long distance … the farther the sound recedes, the weaker it becomes (…) A smaller emitter placed closer, maybe on someone’s pillow, could do the trick … I think those people He has something that hurts them, but it could be in the environment. “
Jay Salpicar: neurologist, Director of the Neurobehavioral Program at Children’s National Medical Center in Washington with 24 years of experience.
“Stress is the main cause of conversion disorder, understood as neurological symptoms that are not related to any known neurological condition and that produces symptoms such as weakness, paralysis and loss of vision or hearing.”
Collen G. Le Prell: audiologist, professor and director of the audiology program at the University of Texas at Dallas. She is one of the leading researchers in the area of prevention of hearing loss. She is the elected president of the National Association for the Conservation of Hearing. He earned his master’s degree in Minnesota and his doctorate in Michigan.
“The community of audiologists wonders what could be the cause of the symptoms described, because nobody has a good explanation for it” and added that “the sudden onset of hearing loss without their being an audible source, is very unusual.”
Andrew Oxenham, psychologist of the Laboratory of Perception and Auditory Cognition of the University of Minnesota. BuzzFeed News published an article referring to the supposed acoustic attacks, where this expert expressed:
“I can not explain in any way that the disease and the hearing loss are related to a sound” … there is no way for an acoustic device to cause hearing damage using inaudible sounds.
“You can not stimulate the inner ear in a way that could cause harm … the only way it could happen is through distortion, which would then make the sound clearly audible, as well as very loud”. Regarding infrasound, he said: “the size of the speakers needed to generate an infrasound like that would be difficult to hide”.
