WebAn acoustic wave is a type of mechanical wave where pressure variation propagates through a material. For example, the speaker of a radio has a membrane that responds to an electrical signal by moving back and forth. WebAcoustic radiation force (ARF) is a physical phenomenon resulting from the interaction of an acoustic wave with an obstacle placed along its path. Generally, the force exerted on the obstacle is evaluated by integrating the acoustic radiation pressure (due to the presence of the sonic wave) over its time-varying surface.
