Acoustic diagnostics of femtosecond laser filamentation [PDF]
The promising application of femtosecond laser filamentation in atmospheric remote sensing brings imperative demand for diagnosing the spatiotemporal dynamics of filamentation. Acoustic emission (AE) during filamentation opens a door to give the insight into the dynamic evolution of filaments in air.

Plastic strain accommodation and acoustic emission during melting of embedded particles [PDF]
Melting point phenomena of micron-sized indium particles embedded in an aluminum matrix were studied by means of acoustic emission. The acoustic energy measured during melting increased with indium content. Acoustic emission during the melting transformation suggests a dislocation generation mechanism to accommodate the 2.5% volume strain required for ...

Acoustic Emission (AE) is an NDE technique that measures the elastic energy released in the form of acoustic waves in materials that undergo irreversible structure changes (e.g., plastic deformation, cracking, rupture). The emitted acoustic waves are captured by sensors attached to the material’s surface.

Enhanced sources of acoustic power surrounding AR11429 [PDF]
Multi-frequency power maps of the local acoustic oscillations show acoustic enhancements (\acoustic-power halos") at high frequencies surrounding large active region. Computational seismic holography reveals a high-frequency \acoustic-emission halo", or \seismic glory" surrounding large active regions.
