Abstract: The sound reproduction includes generating from a customized audio signal an acoustically isolated sound field at a position dependent on a sound field position control signal; providing a listening position signal representing a position of a listener and a listener identification signal representing the identity of the listener; and processing the listening position signal, the listener identification signal, and an audio signal. The sound reproduction further includes controlling, via the sound field position control signal, the position of the sound field dependent on the listening position signal so that the position of the sound field is at the position of the listener; and processing the audio signal according to an audio setting dependent on the identity of the listener to provide the customized audio signal.

Abstract: An exemplary sound reproducing, noise reducing method and system include supplying to a corresponding loudspeaker a useful signal that represents sound to be reproduced and an anti-noise signal that, when reproduced by the corresponding loudspeaker, reduces noise in the vicinity of the corresponding microphone. The method and system further include receiving audio input signals and processing the audio input signals to provide the useful signals so that the useful signals provide a more realistic sound impression for a listener wearing the helmet than the audio input signals.

Abstract: A plurality of speakers are arranged within a listening space. An audio processor is configured to generate a plurality of sound zones within the listening space using the plurality of speakers. The audio processor is programmed to create zone audio signals to generate at least one bright zone in the plurality of sound zones, perform individual delay compensation to the zone audio signals to add additional delay to a subset of the plurality of speakers, the additional delay defined to adjust acoustical output from the subset of the plurality of speakers to match an amount of delay of a most-delayed speaker of the plurality of speakers to the plurality of sound zones, and transmit the zone audio signals to reproduce the at least one bright zone by the plurality of speakers.

Abstract: Disclosed is a loudspeaker array with a multiplicity of array loudspeakers. The multiplicity of array loudspeakers is mounted in a surface of a rigid hemisphere that encloses an acoustic volume. The array loudspeakers are regularly or quasi-regularly distributed over the surface of the rigid hemisphere, and a loudspeaker arrangement includes such an array.

Abstract: At least two closely spaced identical or similar loudspeaker assemblies in a horizontal linear array, each loudspeaker assembly comprising at least two identical or similar loudspeakers pointing in different directions so that the loudspeaker assemblies have adjustable, controllable or steerable directivity characteristics. For example, a control module may drive, adjust, control, or steer the loudspeaker assemblies so that at least one acoustic wave field is generated at least at one listening position.
