Welcome to the Online Forum about the Alleged Acoustic Attacks

The Cuban Expert Committee, which has studied the alleged acoustic attacks on US diplomats in Havana, participates in the online forum entitled: Scientific exchange on the alleged acoustic attacks in Havana.

The main objective is to share information and opinions with the international scientific community or other interested actors. That is why the debate will focus on the exchange on the following questions:

1. Can the described symptoms be a consequence of sonic agents?
2. Other diseases could have caused such symptoms?
3. Is there a probability of psycho-social origin causes?

To participate share your opinion in the comment section. If you want you can also answer our Poll.

    I am Dr. Nelson Gomez, neurologist, member of the expert committe related with the acoustic attacks. In my opiniion the symptoms described in the clinical report sent by state deparment of United state can not be explained for only one cause. The cerebral concussion is not posibble, there is not evidence of craneal trauma and loss of consciousness. I would like to interchange with other neurologist this opinion

  2. Dr. Manuel J. Villar, II Degree ENT specialist and Head & Neck Surgeon

    On a private e-mail, Dr. Michael Teixido – otolaryngologist in Willmington, Delaware – told me that he considers that sonic attacks are plausible and that such technology is accessible and cheap…

    Yes. It is true that sonic weapons exit: sonic, ultrasonic and infrasonic. Nevertheless, to damage a person the waves would have to have high energy intensity and be only a few meters away from the target. If not, the sound would be listen in the surroundings. This never happened. It was selective; within rooms with wall, curtains, and glass windows. That is why, the waves coming from the outside would not cause damage. Is it possible that the devices were within the room? Who could have put it in such place, which are very well protected by the Americans themselves?

    Dr. Teixido, your links do not explain the events.

  3. MI OPINION COMO ESPECIALISTA EN OTORRINOLARINGOLOGIA CON EXPERIENCIA DE VEINTE ANOS EJERCIENDO LA ESPECIALIDAD ME PARECE DIFICIL DE EXPLICAR QUE PUEDA EXISTIR UN DANO AUDITIVO TAN ESPECIFICAMENTE DIRIGIDO HACIA UN GRUPO DE PERSONAS. NO HE VISTO LOS ESTUDIOS CLINICOS DE LAS PERSONAS SUPUESTAMENTE AFECTADAS POR LOQUE NO TENGO UNA EVIDENCIA REAL DE QUE EXISTA UNA AFECTACION. POR OTRA PARTE ME GUSTARIA COMENTAR QUE HE SIDO HUESPED DEL HOTEL NACIONAL, DONDE MI ESTANCIA HA SIDO EXCELENTE, NO HE SIDO TESTIGO DE NINGUNA SITUACION RARA O ANORMAL DURANTE MI ESTADIA EN EL HOTEL.

  4. I did no find rippleys that AP reported. I saw a pitch around 7 kHz, overlapped to a wide band noise perhaps connected to urban background noise at night with cricket songs. There are two shapes of the background sound structure. one of them looks flat, reflects far sound sources (traffic, human steps, weak voices, animals), the other one, local sources dominated by cricket songs. Target sound (those of the so called noise attacks) shows also two behaviors: nearly flat spectrum with high frequency pitch overlapped and, wide band spectrum without pitch. It is something seldom that, some exposed people says they hear nothing out of natural sounds but suffered health impairments related to aural non usual episodes, according press reports abroad. I wonder in such cases, what kind of noise source we are talking about. If we think on infra and ultrasound, health impact repòrted needs exposure to very high intensity event. Other important issue is that no neighbor said that was exposed to a noise attack. So, selectivity of affected people should be considered. This way, I guess sound weapon should be like the ray gun of Flash Gordon. Something like a lasser gun for explaining such high selectivity. We are approaching science fiction. Then, it could be fine to call Mulder and Scully to assist research.

  5. # FalseAcusticAttacks will be used by US Government to sustain its retrograde policy against Cuba and also to justify any kind of action, even military measures. If we take a look to social media and some Internet web sites, it’s easy to see how the incident is being manipulated by their press and the White house itself.
    I think they are preparing the scenario to execute those measure and hostile actions now and in the nearly future. I consider this campaign against my country as an aggression from the American government.
    Cubans are the real victims in this story; we have been always under the attack of several USA Governments for more than 50 years, including the biological ones. Today, a group of renowned terrorists live and conspire against my country in North American territory.
    For that reason, from the Cuban Radio we will continue denouncing the true intentions of #Trump and company. Long Live to the Cuban Revolution! #WeAreAllFidel in #Cuba

    One correction, if I may. I do not believe that deafness or hearing damage “must” be a consequence of high intensity noise exposure. There are many other causes of hearing loss, including ototoxic chemicals or medicines. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4693596/

    Hi, Dr. Pompei. I am glad for being in touch with you. I was talking about noise as cause of the several health impairments. I do not reject other possible causes for the wide range of symptoms and signs reported. Sound level of the noise attacks never goes beyond 80 dB(AF). Sometimes spectra is flat like noise urban background performed with far sources. There is some kind of similarity to white noise at low and medium frequencies. Sometimes a pitch appears at 8 kHz in octave band and on 6300 and 8000 Hz in third octave. Continuous spectrum shows a 7 kHz pitch with bandwidth of 3 kHz superposed to background. Background urban noise has two typical shapes, one of them reflecting cosmopolitan far sources, another reflecting local sources like cricket songs. An important similitude appears between target and background noise with cricket songs. It appears a nearly flat spectrum with a high frequency pitch. Some target sounds shows no high frequency pitch. I remember that some exposed people said that they hear nothing out of rule but suffered consequences.
    Let´s keep talking about this in https://supuestosataques.redciencia.cu/en/2017/11/15/scientific-exchange-on-the-alleged-acoustic-attacks-in-havana/

    Saludos soy otorrino y en estos momentos me encuentro cumpliendo misión en Gabon y quisiera dar mi opinión personal al respecto, realmente existen muchas causas o factores predisponentes a padecer algún tipo de sordera, podría poner dos ejemplos comunes en este país es muy frecuente la sordera neurosensorial en cualquiera de sus clasificaciones, sobre todo en niños que después de sufrir un paludismo grave o complicado con cierto daño neurológico acuden a nuestra consulta con síntomas y signos de sordera, eso en el mejor de los casos; también podría mencionar otro criterio que es valido para todos los países y pienso prudente hablar del estrés siendo éste uno de los causantes y desencadenante de diversas enfermedades y porqué no de una sordera si todos sabemos que el estrés es la manera que tiene de nuestro organismo de responder y defenderse ante cualquier tipo de cambio físico o emocional mediante la liberación de sustancias químicas para corregir el daño que pueda causar el estrés.

    Podríamos decir que algo de estrés puede ser una buena ayuda por la cantidad de hormonas que se liberan, especialmente cuando estás en una situación peligrosa o de placer, pero una gran cantidad de estrés puede causar daños en la salud desde cardiovasculares, neurológicos, entre otros y podríamos incluir daños en la capacidad auditiva.
    Es decir en breves palabras es muy difícil explicar que un daño auditivo tenga una misma causa directa para un grupo selectivo de personas, si conocemos que estas personas interactúan de forma directa con otras personas que no han sufrido dicho supuesto daño, es importante conocer a un enfermo en su ambiente bio-psico-socia para poder intentar hablar o dar un posible diagnóstico.
    Quiero terminar citando algo: Según la Organización Mundial de la Salud, la pérdida de audición se está convirtiendo rápidamente en una de las discapacidades más comunes en el mundo. Aunque muchos tipos de pérdida de audición no se pueden prevenir, reducir los niveles de estrés puede ser beneficioso para la  salud auditiva.

  8. It isn hard to believe that other physical stressors could produce this wide range of symptoms of health impairments. Climate should be no ethiology because those houses of diplomats were provided with air conditioners devices which reduce heat load of tropical climate and, variety of reactions does not match with direct climate effect . Non ionizing radiation is connected to some acute effects related to heat exchange and physiological disturbance based on electric currents induced in human inner organs. Chronic effects such as Infant Leukemia remain under discussion. Ionizing radiation is related more to chronic effects such as radiological syndrome and stochastic reaction such as cancer disease. It would be necessary consider alternative hyphotesis.

  9. Hola soy enfermera miembro de la brigada medica cubana en haiti considero que esto no es mas que una excusa para seguir desacreditando a nuestro pais no es posible que de existir una forma de atentar contra el sistema auditivo solo afecte a un grupo determinado de personas
