cruising for burgers Posted April 3, 2013 Report Share Posted April 3, 2013 Quote Infrasonic waves from the meteor that broke up over Russia's Ural mountains last week were the largest ever recorded by the CTBTO's International Monitoring System. Infrasound is low frequency sound with a range of less than 10 Hz. The blast was detected by 17 infrasound stations in the CTBTO's network, which tracks atomic blasts across the planet. Listen to the audio files of the infrasound recording after it has been filtered and the signal accelerated. Read more:http://www.ctbto.org/press-centre/pre... The recording was sped up 135 times, in reality it lasted 25 minutes! The sound files were produced by CTBTO's infrasound guru Pierrick Mialle. For those interested in getting really techie, Pierrick says the sound file he produced lasts 14 seconds (which corresponds to 31.5 minutes at real "speed"). When you listen you can hear the meteorite detection for about 8 seconds (or 18 minutes at real "speed"). Pierrick modified the speed but also changed the frequency content -- so that you can better hear the signal against any background noise. To get a more precise duration of the signal that was recorded by the Kazakh infrasound station than you hear in the animation, Pierrick used specialized software and voilà - we have 25 minutes. Pierrick is part of a team of dedicated scientists in the CTBTO's International Data Centre -- who spend their days monitoring the world for nuclear tests. Between 17 and 21 June scientist from all over the world will be meeting in Vienna to promote the wider scientific application of data that are used for test-ban verification.
