A device comprising: at least four omni-directional microphone elements, a loudspeaker, and a housing, wherein the housing is configured to support the microphone elements around a circle or an ellipse in a first, horizontal orientation and the loudspeaker in a orientation such that the circle or ellipse is concentric to the loudspeaker axis and/or sound radiation axis of the loudspeaker, wherein the microphone elements are arranged (i) such that appropriate phase characteristics and delay characteristics achieve a first zone of insensitivity in a first vertical direction over an audible range of frequencies and a second zone of sensitivity in a second horizontal direction over the audible range of frequencies; and (ii) such that the microphones are arranged relative to the loudspeaker so that the audio from the loudspeaker is also cancelled in the zone of insensitivity by the microphone elements, wherein an elevation response between the first zone and the second zone approximate cosine elevation angle, characterized in that the relative phases of a first one of the microphone elements and a third one of the microphone elements are arranged at approximately 0 and 180 degrees and the relative phases of a second one of the microphone elements and a fourth one of the microphone elements are also set to approximately 0 and 180 degrees, such that the second zone of sensitivity may be rotated in the horizontal direction to a desired angle by combining a proportion of the signal from the first microphone element and the third microphone element proportional to the cosine of the desired angle and a proportion of the second microphone element and the fourth microphone element proportional to the sine to create a steerable figure eight second zone of sensitivity. at least four omni-directional microphone elements, a loudspeaker, and a housing, wherein the housing is configured to support the microphone elements around a circle or an ellipse in a first, horizontal orientation and the loudspeaker in a orientation such that the circle or ellipse is concentric to the loudspeaker axis and/or sound radiation axis of the loudspeaker, wherein the microphone elements are arranged (i) such that appropriate phase characteristics and delay characteristics achieve a first zone of insensitivity in a first vertical direction over an audible range of frequencies and a second zone of sensitivity in a second horizontal direction over the audible range of frequencies; and (ii) such that the microphones are arranged relative to the loudspeaker so that the audio from the loudspeaker is also cancelled in the zone of insensitivity by the microphone elements, wherein an elevation response between the first zone and the second zone approximate cosine elevation angle, characterized in that the relative phases of a first one of the microphone elements and a third one of the microphone elements are arranged at approximately 0 and 180 degrees and the relative phases of a second one of the microphone elements and a fourth one of the microphone elements are also set to approximately 0 and 180 degrees, such that the second zone of sensitivity may be rotated in the horizontal direction to a desired angle by combining a proportion of the signal from the first microphone element and the third microphone element proportional to the cosine of the desired angle and a proportion of the second microphone element and the fourth microphone element proportional to the sine to create a steerable figure eight second zone of sensitivity.
