A microphone assembly includes a housing including at least one first tube in communication with at least one first cavity, at least one second tube in communication with at least one second cavity, one third tube in communication with at least one third cavity, and at least one microphone element separating the first, second and third cavities, wherein sound waves are received in the first, second, and third tubes and directed into the cavities and received by the microphone element. A method for converting sound waves into an electrical signal includes receiving the sound waves through at least three tube openings and directing the received sound waves along tube pathways into at least a first, second, and third cavity to a microphone separating the first, second, and third cavity. The method further includes converting the received sound waves into an electrical signal with the microphone. |
