INTRO: We often think of astronomy as a visual science with beautiful images of the universe. However, astronomers use a wide range of analysis tools beyond images to understand nature at a deeper level.
Data sonification is the process of converting data into sound. It has powerful applications in research, education and outreach, and also enables blind and visually impaired communities to understand plots, images and other data.
Its use as a tool in science is still in its early stages – but astronomy groups are leading the way.
In a paper published in Nature Astronomy, my colleagues and I discuss the current state of data sonification in astronomy and other fields, provide an overview of 100 sound-based projects and explore its future directions.
Imagine this scene: you’re at a crowded party that’s quite noisy. You don’t know anyone and they’re all speaking a language you can’t understand – not good. Then you hear bits of a conversation in a far corner in your language. You focus on it and head over to introduce yourself.
While you may have never experienced such a party, the thought of hearing a recognisable voice or language in a noisy room is familiar. The ability of the human ear and brain to filter out undesired sounds and retrieve desired sounds is called the “cocktail party effect”.
Similarly, science is always pushing the boundaries of what can be detected, which often requires extracting very faint signals from noisy data. In astronomy we often push to find the faintest, farthest or most fleeting of signals. Data sonification helps us to push these boundaries further... (MORE - details)
