What is the infraredound?

Infrasound is a sound with too low frequency to be detected by humans. They range from about 17 to 16 Hertz, limits of human hearing, up to 0.001 Hertz. The sound wave, which is 1 Hertz, has a period of one second. The range of human audibility is around 20 to 20,000 Hz, while women are able to hear slightly higher frequencies, which is the ability that reduces with age. Infrasound can be considered slow, periodic thunder - is generated by large processes such as avalanches, volcanoes, tornadoes, ocean waves, earthquakes and meteors. It can be generated by large chemical or nuclear explosions. Because it is one of the symptoms of nuclear testing, the infraredound is continuously monitored worldwide by a comprehensive organization of a nuclear test agreement. It is assumed that ambieultrazvuk nt, sound too high to be detected by humans can be the cause of some ghost news. It can even cause people to hallucine gray characters. In the experiments reported up to 1/5 subjects suchfeelings when they were exposed to ultrasound in a laboratory environment. At the right frequency, the infraredound can cause human organs to vibrate, causing pain. For this reason, it was the goal of weapons research and various prototypes were made and tested.

Infrasound is at the right frequency to cause confusion on fragile objects such as glass windows and homemade trinkets. With sufficient energy, it can even collapse the walls. If the great asteroid affect the Earth or oceans, the infra -rassed wave would move from the ground zero at the speed of sound, causing damage to everything in its path. The characteristic frequency of the sound produced by surfing the ocean is 17 cycles per second, which is just a shy infrashdate, so it is audible to people.

Infrasound is based on many natural processes. Waterfalls, Antarctic ice and even tigers emit an infraredound that can be felt on miles daLeko. The infrashound can be easily picked up with acoustic tools. One day there may be cyber implants that allow people to scan infrared.
