Abstract
Sound is uniformly distributed in a confined space such as the passenger in of an aircraft by connecting an acoustic drive member to an entire wall panel or to an entire ceiling panel of the cabin structure whereby such panels act as the membrane of a loudspeaker. By properly spacing the membrane panels the entire cabin space is filled with sound in stereophonic fashion, whereby the seating arrangement becomes independent of the loudspeaker locations and vice versa.
