The proposed higher order designs have similar inter sensor spacings as traditional first and second order differential arrays. The Jacobi-Anger expansion is used to exploitKeywords: Directional microphones; Higher order; Inter-sensor spacing; Jacobi-anger expansion; Microphone arrays; Microphone signals; Second orders; Design; Sensors; Microphones; acoustics; article; equipment design; instrumentation; noise; signal processing; sound201010.1121/1.34023412016-02-24
