The normal methods used are the delay-and-sum beam-forming and spherical harmonics beam-forming. These methods give a bad low frequency resolution and since much noise generated in a car is of low frequency these methods are not optimal. Here the mapping is done by solving an inverse problem with a transfer matrix between the volume velocity of the sources and the measured pressures at the microphone array. The problem is very ill-posed and therefore regularization have to be applied when the transfer matrix is inverted in order to give good results.<\/p>\n<p><strong>Bio<\/strong><br \/>\nSidsel Marie N\u00f8rholm got a Master Degree in Sound and Acoustic Technology at the Technical University of Denmark in August 2012.
