Schematic top view of the microphone array. Each black box represents one omnidirectional microphone. There are four sets of four microphones. Within each set, four microphones are arranged in the front-back direction as two pairs of microphones. The microphones within a pair are spaced 10 mm apart. The medial two microphones in a set (separating the front-back pairs) are spaced 15 mm apart. Finally, each set is spaced horizontally 66.67 mm apart, yielding a total array length of 200 mm.
