Definition
C1Materials Science
(technical)The generation of sound waves due to rapid internal changes in a material, such as cracking or deformation.
Example
- Acoustic emission is often monitored to detect early signs of structural failure in bridges.
C1Non-Destructive Testing
(technical)A technique that detects and analyzes sound waves produced by stress changes in materials to monitor their integrity.
Example
- Engineers use acoustic emission to ensure the safety of aircraft components.
