C6.3 - Measurement Error and Statistics of Pairing Microphones for Directional Arrays in Hearing Aids

D. M. Warren & Ch. B. King
Directional acoustic sensing in hearing aids has been demonstrated to be an effective means of improving the understanding of speech in background noise. Directionality in hearing aids may be implemented as a pair of omnidirectional microphones, digitally processed to form a directional response. It is highly desirable in hearing aid design for the device to be small and unseen when worn, so the distance between the mircophones must be short, between approximately 8mm and 16mm....
