Terrifying tiger needle
Text created by automatic translator Elia and has not been subsequently revised by translators. Elia Elhuyar
Animals, and many times people, are trapped by the fear and laziness of the tiger. Scientists investigating bioacoustics have clarified why, apparently, when making the needle, it emits sound waves that are below the 18 heroes and although their victims do not hear, they perceive the effect, which is immobile. Humans, for example, are able to hear the waves emitted between 20 and 2,000 hertz; whales, elephants, rhinos and tigers can produce below. The next phase of the research will be to know if, in addition to generating low-frequency sounds, they have listening capacity.
