The Sound of a Black Hole - 10 Hours - Black Screen

Nasa released the first image of a black hole on April 10, 2019. This might leave you wondering, do black holes have a sound? It is often stated that there is no sound in deep space. This is true because sound requires a medium (like water or air) to vibrate through where it can then be interpreted by the human ear. Black holes, however, do create sound. In galaxy clusters a black hole will suck superheated gasses towards it, a portion of the gasses though are pushed away from the black hole in wave which creates vibrations (sounds) through the medium of the gasses. Images of the propagation of waves were detected by Nasa via x-ray and were then translated into data and then audio waveforms.

The frequencies were originally in Bb 57 octaves below middle C on a piano. The x-rays were originally recorded over a period of 53 hours. The data translated to audio was later sped up to the range of human hearing. Interestingly black holes of different sizes all generate the same Bb resonance.

This recording takes Nasa's audio clip (which had compressed days into seconds) and slows it down to be closer to the actual sound of the black hole. Please note this sound has very low components and may be difficult to hear on mobile devices. For a more audible version on these devices try adding to the mixer and adjusting pitch.
