A sound baffle is used to muffle noise and echos and reduce their magnitude. Sound baffles are frequently used in wall and ceiling panels of buildings to dissipate the sound compression waves and the amount of sound reflection and reverberation.

In 1973, Mrs. Elwood (Pearl P.) Randolph, a school bus driver in Virginia, won a new school bus in nationwide contest held by Wayne Corporation soliciting new safety ideas for her suggestion that sound baffles be installed in the ceiling panels of school buses. In 1981, they were first made mandatory by the state of California.
