“Star Wars introduced a new way for using the five screen speakers [in theaters]. By pushing left and right sound channels to the farthest out speakers the pair just inside those was made available. Lucas' mixers then placed low frequency effects in those speakers, and named it the 'baby boom' channel. Human ears can hear frequencies up to around 20,000 hertz, and down to around 20 Hertz for very low sounds.
