Acoustic techniques are experimental or analytical methods that exploit the generation, propagation, and detection of sound or ultrasound waves to probe material, structural, or environmental properties. They encompass approaches such as acoustic emission monitoring, ultrasonic testing, impedance and resonance measurements, and acoustic spectroscopy. These techniques rely on wave–matter interactions (reflection, refraction, scattering, absorption) to infer parameters including elastic moduli, defect distributions, phase composition, flow characteristics, or biological tissue structure. Acoustic methods are widely used for nondestructive evaluation, in situ monitoring, and real-time sensing, often offering high sensitivity to microstructural changes and the ability to operate in opaque or complex media.
