Black Hole Sounds Terrible, Reveal Sound Clips By NASA
Have you ever wondered about black hole sound? Maybe no, as we are surmounted with hundreds of theories suggesting a conception that there exist no sound waves in space, especially in black holes. However, a recent exploration made by NASA astronauts presents an entirely different picture.
Recently, NASA shared an audio clip of sound waves presenting how do black holes actually sound like. In its post, the agency added a caption, “The misconception that there exists no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we’ve picked up actual sound. Here it’s amplified, and mixed with other data, to hear a black hole!“

The space agency prepared the sound clip by amplifying and mixing the vibrations that astronomers extracted from the black hole at the centre of the Perseus galaxy cluster.
With its clip, NASA clarified that it was not “intentionally made ominous, but the sound added with the visuals is amplified a lot, while other sounds added into it are interpreted from light data“.
The agency stated, “One of the motivations to create such data sonification is the desire to share the science with more people”.
Views Of Space Experts On Black Hole Sound
According to space scientists, the black hole at the centre of the Perseus galaxy has been associated with sound since 2003. At that time, astronomers discovered that pressure waves emitted from the black hole caused ripples in the cluster’s hot gas. After learning these parameters, the space agency translated the emerging pressure waves into a note, NASA explained in May while releasing the sound clip.
In addition to the above-mentioned facts, the space agency stated that the sound waves emerging from black holes are too low for humans to hear, as these waves are of 57 octaves value level. As this value lies below middle C, humans cannot hear those waves.
How Do Space Agency Produced Sound Waves?
The space agency produced the sound waves by resynthesizing them into the range of human hearing capabilities. For this, they scaled multiple octaves above their original pitch with the extracted vibrations. In addition to sound waves, the agency shared similar notes by translating astronomical data into sound.
