Directional microphones are best noted for their noise reduction properties in communication systems. Close-talking differential microphones are particularly useful when the noise environment disturbs the ability to communicate without error, such as in public and cellular telephony, aircraft communications, etc. These differential microphones work best when they are spaced within 1 cm from the lips of the talker where the sound field has a large gradient. For a plane-wave sound field, the… CONTINUE READING
