Abstract

This study examines the estimation of the surface impedance of an absorber with microphone arrays. Two array geometries are compared - a rigid spherical array and a double layer planar array. The impedance is estimated via reconstructing the sound field (pressure and particle velocity) on the absorber's surface, using a plane wave expansion. The comparison is carried out by studying the numerical properties of the two arrays as well as through experimental tests.
