Sound radiating arrangement and method of providing the same

Abstract

The invention relates to a sound wall comprising in total M elements comprising a front face (F), where the sound wall () has a lateral extension along an x-axis and a vertical extension along a y-axis, where the sound wall () comprises N elements (), where N≤M, which N elements in the front face (F) of each respective of these N elements are provided with a sound radiating unit, such as one or more loudspeaker units, configured to radiate sound energy from the respective front face and into the surroundings, such that a sound field can be created in front of the sound wall; where the sound wall is provided with signal providing means configured to provide the sound radiating units with a signal that is a combination of input signals, such as the left and right channel signals S(t), S(t) of a stereophonic signal. In embodiments of the invention, the sound wall () further comprises A elements (), where A≤M−N, which A elements () are provided with sound absorbing means associated with the front face (F), whereby the sound wall () can be used to reduce the reverberation time of a room or other enclosure, in which the sound wall () is provided and/or H elements (), where H≤M−N−A, which H elements () comprises hardware components configured to control and provide signals to the sound radiating units in said N elements (). The invention also relates to a method for controlling a sound field in front of the sound wall.
