The scaling up of the sound signals means that what we are hearing is actually 144 quadrillion and 288 quadrillion times higher than the signals' original frequencies.įor scale, a quadrillion (a million billion) is 1,000,000,000,000,000 - that's 15 zeros. The radar-like scan around the image allows us to hear waves emitted in different directions.The signals were resynthesised into the range of human hearing by scaling them up by 57 and 58 octaves above their actual pitch.The sound waves were extracted outwards, from the centre of the cluster.Since MacOS does not provide a native way for users to get the internal/system audio, a third party solution (BlackHole) is required. The black hole at the center of Perseus has been associated with sound since 2003 when astronomers discovered that pressure waves emitted from the black hole caused ripples in the cluster’s hot gas that could be translated into a note, NASA explained in May when it first released the audio. It is developed by Devin Roth / Existential Audio, and is commonly used to route audio to different applications. In 2003 astrophysicists working with NASA’s orbiting Chandra X-ray Observatory. Here's the gist of how the sonification was put together, according to NASA: BlackHole is a modern, open source virtual audio driver for MacOS. In space you can’t hear a black hole scream, but apparently you can hear it sing. NASA says the sonification of the Perseus galaxy cluster is unlike any other done before because it uses the actual sound waves discovered by its Chandra X-ray Observatory space telescope. It was designed to improve sound quality in domestic. ( NASA/CXC/IoA/A.Fabian et al.) How the sound of a black hole was created Clayton Shaw of Spatial Computer: Our Black Hole is an active acoustic pressure reduction device. “In some ways, this sonification is unlike any other done before… because it revisits the actual sound waves discovered in data from NASA’s Chandra X-ray Observatory.Sound waves around the black hole in the Perseus galaxy are thought to have been produced by 'explosive events'. “Astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note - one that humans cannot hear some 57 octaves below middle C,” they said in a statement. The agency described it then as a result of pressure waves sent out by the black hole, saying it was a whopping 57 octaves below middle C, which means scientists had to raise the frequency quadrillions of times to make it audible. The sound itself comes from Nasa’s Chandra X-ray Observatory, and was actually released in May. space agency tweeted what it called a remixed sonification of the black hole at the center of a galaxy cluster known as Perseus, which lies about 240 million light-years away from Earth. “This sounds just like my stomach at 6.30pm when the early evening shows have wrapped. New bjork sounds amazing - Thiago Guimarães August 22, 2022Īnd one section of the internet felt it sounded more like bodily functions than anything else. The black hole at the center of Perseus has been associated with sound since 2003 when astronomers discovered that pressure waves emitted from the black hole caused ripples in the cluster’s hot gas that could be translated into a note, NASA explained in May when it first released the audio. ExistentialAudio / BlackHole Public Notifications Fork 464 Star 11k 2 channel vs 16 channel 290 Unanswered BruceAC asked this question in Q&A BruceAC on As a new user of Blackhole, I am curious regarding all the differences between 2 and 16 channel other than the number of channels.
