Brownian Movement/Motion

First demonstrated by Dr. Robert Brown (about 1827), the random, rapid, vibratory movement of tiny particles in a fluid such as water or air caused by collisions between them and molecules of the fluid. Brownian movement is known to be a significant contributor to the self-noise of microphones due to the action of moving particles against the diaphragm.
