Atmospheric and Cosmic Infrasound Detection Techniques.

Abstract eng:
By using the current infrasonic techniques and technologies, it is possible to effectively and efficiently detect signals generated by meteors, bolides and other sources. The geolocalization of the explosion source is the result of the intersection of infrasonic signals generated by the bolide obtained in more than one infrasonic station. It is also possible to relate the periods of such signals with the energy source of the fireball. Auroras are other phenomena mat are detected by infrasonic arrays. The recently discovered infrasonic waves are those generated in the depths of sidereal space and they are the lowest-frequency sounds ever found in the universe. It has been developed an early-universe sound simulation software using the data obtained by the scientists of the Wilkinson Microwave Anisotropy Probe, WMAP. Moreover, the Laser Interferometer Space Antenna, LISA, space mission, may be able to detect very low frequency gravitational acoustic waves produced in the space.
