This paper presents some simple microphone arrays for communication in harsh noisy environments and for speakers using face masks. These arrays have better frequency responses than those developed in previous work, keeping gain match and the same uniform microphone spacing as in the past1 This paper also discusses the effects of microphone spacing and gain mismatch on array characteristics, the angular variations of source attenuation properties of these arrays and their robustnesses in respect to angular variation.
