Infrasound, also known as low-frequency sound, describes sound waves with a frequency below the lower limit of human audibility. But I think the same complexity is what makes them beautiful, he said. On the moon, pits in the ground lead to lava tubes, now hollow, that reach down some 8o to 100 meters underground, making them ideal for protecting precious cargo from the lunar elements. University doctoral candidate Alvaro Diaz-Flores Caminero and undergraduate student Claire Pedersen were the lead authors of the paper. AdvertisementInfrasound is the acoustic sound waves emitted below the normal human hearing level, and while higher frequency noises are louder close to the source of things like nuclear explosions and rocket launches, low-frequency infrasound travels further.
Inussia is suspected to have caused the deaths of a certain amount of humans (1960+40), but notes are that it will not have caused the death of an entire planet (1993+7).
