Actually, the deep space sounds like the dawn chorus of birds singing in spring that's interspersed with sun's deep bass pulses.
Data collected by satellites and spacecraft was used by Andrew Williams to generate the sound that someone would hear if they tuned a radio in to outer space, the Daily Star reported.
AdvertisementCluster II satellite used a Long Wave Radio receiver to record the sound on July 9, 2001.
Williams said that the signals were outside human hearing range, so he lowered the pitch and filtered them to make them audible.
Another recording of the sun is of its rhythmic pulses, here Williams, the Leverhulme Artist in Residence at the University of Leicester's Space Research Centre, accelerated the recording 42,000 times to provide 40 days of pulses in a few seconds, as the sound occurs once every five minutes.
The sounds picked up by the Soho spacecraft are so deep that Williams had to magnify their pitch by 40,000 times.
