摘要： A method and apparatus for capturing audio including a ceiling mountable second-order differential microphone module. The module including a solid planar baffle having a generally centered aperture, at least one mounting foot to suspend the solid planar baffle approximately parallel with a rear reflecting plane and to space the solid planar baffle at a predetermined distance below the rear reflecting plane, a differential microphone sealably coupled to the planar baffle with a first side of the differential microphone acoustically exposed to an area above the planar baffle and a second side of the differential microphone acoustically exposed to an area below the planar baffle, and a mounting means for mounting the solid rear reflecting panel to the room ceiling.
