*Foley is a term used to describe the all of the “natural” sound effects which contribute to our sense of
reality in motion pictures. These effects are created in a special sound stage in sync with the action of
the film. The process was named after Jack Foley who invented the system of adding the sound of
footsteps to early talking motion pictures in order to enhance their believability.
