The sound was originally captured in the Perseus Galaxy. It was done by the Chandra X-ray Observatory, which is already known for "sonifications" or reproductions of galactic data into sounds.  

Now, humans can hear the sound of the black hole forever.  

Since 2003, the Perseus Galaxy has been known to have a noise-making black hole at its centre. At the time of discovery of this black hole, scientists had observed it for 53 hours.

According to the observatory, the "copious amounts of gas" in this galaxy act like a medium needed for sound waves to travel on. It also somehow proves that space isn't a complete vacuum.    

This noise was around 57 to 58 octaves lower than middle C and at about a B flat.  

To make it hearable for humans, the note was scaled upwards around 144 quadrillion and 288 quadrillion times by the scientists at the observatory.
