3. (Med.) The act of tapping or striking the surface of the body in order to learn the condition of the parts beneath by the sound emitted or the sensation imparted to the fingers. Percussion is said to be immediate if the blow is directly upon the body; if some intervening substance, as a pleximeter, is, used, it is called mediate.
