Acoustic Microphone Array Geometry Calibration
Today, we are often surrounded by devices with one or more microphones, such as smartphones, laptops, hearing aids, and wireless microphones. If they are part of an acoustic sensor network, their distribution in the environment can be beneficially exploited for various speech processing tasks. Applications like speaker localization, speaker tracking require the knowledge of the geo- metric configuration of the sensors. It is also benefital for severals methods of speech enhance- ment by beamforming. Therefore, acoustic microphone geometry calibration has recently become a very active field of research [5].
