The Takeaway
Everything is in constant motion at the atomic scale, but we usually only see this as data. By converting these vibrations (phonons) into audio, this project allows people to listen to a crystal's 'song' to identify its mechanical and thermal properties.
From the abstract
Solid materials may appear static, but at the atomic scale they are in constant vibrational motion. These vibrations, described by phonons, govern many key material properties, including structural stability, mechanical strength, optical behaviour, and thermal transport. Understanding phonon physics is therefore central to the rational design of materials with targeted functionalities.Singing Materials is a research project that explores how sonification can be applied to this domain.
