American Teens Hear Strange High-Pitched Sound at Havana Airport

Zonic devises

On December 31, 2017, an American father in his 40’s and his son and daughter, ages 15 and 14, were at Havana’s Jose Marti International Airport. Around 2:00 p.m. they were waiting to board their return Delta flight to Atlanta.

The teens asked their father what was making the annoying high-pitched noise. The father, however, heard nothing and asked them if they could tell the direction of this noise. They could and tracked the sound to a green box on a wall near the ceiling of the departure area. The teens also said the device gradually changed the pitch to where it was inaudible and then it gradually came back to the pitch where they could hear it.

Here are the father’s photographs of that device in the upper right of the airport wall and of a closeup of the device showing a label with the words “toscano” and “Zoonic” and images of an insect, reptile, rodent and bird.

A quick Internet search revealed that it is an “ultrasound animal repeller” that “makes the stay of birds, reptiles, and rodents uncomfortable” by emitting “vibrations of high frequency (ultrasounds), alternating between ranges for different animals, so that they will never nest.”

In addition, the device’s Installation and Operating Instructions (in English) state that it has a “micro-switch with two positions, HIGH and LOW. . . . Normally better results are obtained in LOW (frequency) position, but may be bothered [bothersome?] for persons. It is recommended [to] use this position when usually not working [with] any person[s] around.”

The device’s manufacturer apparently is Toscano , which describes itself as an “electronics development & manufacturing” firm in Sevilla, Spain.

By all indications, this device is not manufactured with the intent to cause harm to humans. Some, but not all, of its sounds are audible and annoying to some people, but not others. The audibility of the device is not constant given that it gradually changes pitch to go beyond the hearing range and then it gradually comes back to the range.

This report raises many questions pertaining to the medical problems experienced by some U.S. and Canadian diplomats in Havana that by some accounts are caused by sonic sounds [1] These questions include the following:

  • How many of the devices have been sold to persons in Cuba?
  • What persons in Cuba bought the devices?
  • Where have they been installed in Cuba?
  • Who installed them?
  • Who maintains them?
  • Have any of these devices been installed in or near the U.S. or Canadian embassies or their diplomats’ residences or Hotel Nacional or Hotel Capri?
  • How difficult would it be for a single device to be obtained by an individual or entity in order to harass American/Canadian diplomats?
  • Are the devices in need of calibration and recalibration?
  • If they are not susceptible to malfunction, then why are they audible to only some people and not others?
  • Are the devices capable of producing health problems? (Either in their normal state or altered?)
  • Did the U.S., Canadian or Cuban government notice these devices in their investigations? If so, what did they conclude?

In the fall of 2016, a series of U.S. diplomats began suffering unexplained losses of hearing and memory problems. After months of investigation, U.S. officials concluded that the diplomats had been attacked with an advanced sonic weapon that operated outside the range of audible sound and had been deployed either inside or outside their residences and in at least one hotel.

TRAVEL TO CUBA WARNINGS

Get travel vaccines and medicines because there is a risk of these diseases in Cuba.
TyphoidYou can get typhoid through contaminated food or water in Cuba. CDC recommends this vaccine for most travelers, especially if you are staying with friends or relatives, visiting smaller cities or rural areas, or if you are an adventurous eater.
Hepatitis ACDC recommends this vaccine because you can get hepatitis A through contaminated food or water in Cuba, regardless of where you are eating or staying.
Ask your doctor what vaccines and medicines you need based on where you are going, how long you are staying, what you will be doing, and if you are traveling from a country other than the US.
RabiesRabies can be found in dogs, bats, and other mammals in Cuba, so CDC recommends this vaccine for the following groups:

  • Travelers involved in outdoor and other activities (such as camping, hiking, biking, adventure travel, and caving) that put them at risk for animal bites.
  • People who will be working with or around animals (such as veterinarians, wildlife professionals, and researchers).
  • People who are taking long trips or moving to Cuba
  • Children, because they tend to play with animals, might not report bites, and are more likely to have animal bites on their head and neck.
Hepatitis BYou can get hepatitis B through sexual contact, contaminated needles, and blood products, so CDC recommends this vaccine if you might have sex with a new partner, get a tattoo or piercing, or have any medical procedures.

Note: Zika is a risk in Cuba. Zika infection during pregnancy can cause serious birth defects. Therefore, pregnant women should not travel to Cuba. Partners of pregnant women and couples planning pregnancy should know the possible risks to pregnancy and take preventive steps
