The broad practice of turning the intrinsic properties or dynamic behaviors of materials—their stress under load, thermal expansion, nanoscale vibrations, or degradation over time—into sound. This allows engineers to "listen for failure" in bridges or airplane wings, or for artists to create installations where a sculpture's sound changes as it rusts or bends.
Sonification of Materials Example: To test a new carbon fiber alloy, engineers attach sensors and sonify the material's stress during load tests. A clean, harmonic sound indicates even stress distribution. The sudden emergence of a grinding, dissonant frequency directly signals the onset of a micro-fracture long before it's visible, providing an acoustic early-warning system.
