Microphone array
From Wikipedia, the free encyclopedia
A microphone array is a set of multiple microphones operating in tandem. This is shown to have 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
- High fidelity original recordings
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.
There are some implementation of microphones arrays that are really big. At the Massachusetts Institute of Technology, an array of 1020 microphones [1] has been built.
