Microphone Array Shape Calibration in Diffuse Noise Fields
Iain A. McCowan, Mike Lincoln, Ivan Himawan · IEEE Transactions on Audio Speech and Language Processing · 2008
This correspondence presents a microphone array shape calibration procedure for diffuse noise environments. The procedure estimates intermicrophone distances by fitting the measured noise coherence with its theoretical model and then estimates the array geometry using classical multidimensional scaling. The technique is validated on noise recordings from two office environments.
