In astronomy, the use of sound instead of light is breaking down barriers to participation and providing insight into the Universe.
. Sonification describes the conversion of data into digital audio files, which allows them to be heard, as well as read and seen. The researchers featured inshow that sound representations can help scientists to better identify patterns or signals in large astronomical data setsThe work demonstrates that efforts to boost inclusivity and accessibility can have wider benefits.
In August, NASA tweeted about the sound of the black hole at the centre of the Perseus galaxy cluster; the attached file has since been played more than 17 million times. In the same month, Arcand and others converted some of the first images from the James Webb Space Telescope into sound. They worked under the guidance of people who are blind and visually impaired to map the intensity and colours of light in the headline-grabbing pictures into audio.
Scientists in other fields have also experimented with data sonification. Biophysicists have used it to help students understand protein folding. Aspects of proteins are matched to sound parameters such as loudness and pitch, which are then combined into an audio representation of the complex folding process.
