Optimization of the diffuse field performance of a miniature highly directional array microphone.
The focus of this development effort has been the design of a small highly directional array microphone. Such a design is valuable for applications where the directivity of 1st order microphones is too low and the physical size of traditional shotgun or parabolic microphones prohibits their use. Application examples include hearing aids, automotive mobile phones, and interview situations with less visibility of the microphones.
