Microphone Array and Array Microphones
A microphone array is any number of microphones operating in tandem. There are many applications:
- Systems for extracting voice input from ambient noise (notably telephones, speech recognition systems, hearing aids)
- Surround sound and related technologies
- Locating objects by sound: acoustic source localization, e.g., military use to locate the source(s) of artillery fire. Aircraft location and tracking.
- High fidelity original recordings
- 3D spatial beamforming for localized acoustic detection of subcutaneous sounds
Typically, an array is made up of omnidirectional microphones distributed about the perimeter of a space, linked to a computer that records and interprets the results into a coherent form.

Famous quotes containing the words microphones and/or array:
“The present century has not dealt kindly with the farmer. His legends are all but obsolete, and his beliefs have been pared away by the professors at colleges of agriculture. Even the farm- bred bards who twang guitars before radio microphones prefer Im Headin for the Last Roundup to Turkey in the Straw or Father Put the Cows Away.”
—For the State of Kansas, U.S. public relief program (1935-1943)
“Any one who knows what the worth of family affection is among the lower classes, and who has seen the array of little portraits stuck over a labourers fireplace ... will perhaps feel with me that in counteracting the tendencies, social and industrial, which every day are sapping the healthier family affections, the sixpenny photograph is doing more for the poor than all the philanthropists in the world.”
—Macmillans Magazine (London, September 1871)
