Definition of acoustic impedance in English:

acoustic impedance

noun

Physics

The ratio of the pressure over an imaginary surface in a sound wave to the rate of particle flow across the surface.
〔物理〕声阻抗
Example sentencesExamples
- These invariably cause seismic waveform scattering and degeneration as a result of factors such as surface geometry and acoustic impedance contrasts through the lavas.
- Dipping energy of the strength portrayed by the ILP lines must represent parallel layers of contrasting acoustic impedance.
- The harmless waves are aimed at the part to be examined, and reflections are detected from tissue components in proportion to their acoustic impedance.
- From the acquired measurements of sound speed and acoustic impedance, the important physical properties of in situ density and adiabatic compressibility could be calculated.
- Signal processing procedures have been developed that estimate acoustic impedance and compressional wave attenuation with depth beneath the sea floor.
