Electroacoustic phenomena arise when ultrasound propagates through a fluid containing ions. The associated particle motion generates electric signals because ions have electric charge. This coupling between ultrasound and electric field is called electroacoustic phenomena. Fluid might be a simple Newtonian liquid, or complex heterogeneous dispersion, emulsion or even a porous body. There are several different electroacoustic effects depending on the nature of the fluid.
- Ion Vibration Current/Potential (IVI), an electric signal that arises when an acoustic wave propagates through a homogeneous fluid.
- Streaming Vibration Current/Potential (SVI), an electric signal that arises when an acoustic wave propagates through a porous body in which the pores are filled with fluid.
- Colloid Vibration Current /Potential (CVI), an electric signal that arises when ultrasound propagates through a heterogeneous fluid, such as a dispersion or emulsion.
- Electric Sonic Amplitude (ESA), the inverse of CVI effect, in which an acoustic field arises when an electric field propagates through a heterogeneous fluids.

Famous quotes containing the word phenomena:
“Many of the phenomena of Winter are suggestive of an inexpressible tenderness and fragile delicacy. We are accustomed to hear this king described as a rude and boisterous tyrant; but with the gentleness of a lover he adorns the tresses of Summer.”
—Henry David Thoreau (18171862)
