Claim One:
1. A method for estimating the position of N sound-emitting transducers, such as loudspeakers, where N≧2, where the method comprises the following steps: determining the individual distances d ij , or quantities uniquely defining these distances, such as the individual propagation times t ij , between any given sound-emitting transducer (T i ) and each of the remaining sound-emitting transducers (T j ); based on said individual distances d ij between any given sound-emitting transducer (T i ) and each of the remaining sound-emitting transducers (T j ), i.e. based on a distance matrix M comprising the individual distances d ij or based on said other quantities, such as said t ij , estimating the relative co-ordinates (x i ′, y i ′, z i ′) of each of said sound-emitting transducers (T 1 , T 2 ,. .. T N ) by means of a multidimensional scaling (MDS) technique or algorithm; where the method furthermore comprises error identification and correction steps for execution when a stress value provided by said MDS algorithm exceeds a given maximum value; wherein said distance matrix M comprising the individual distances d ij or a matrix comprising said other quantities, such as said t ij , is subdivided into sub-matrixes, where the MDS algorithm is applied on each of said sub-matrixes, thereby providing stress values for each of these sub-matrixes, such that the or those sub-matrix(es) resulting in stress value(s) outside a given tolerance region are determined to comprise at least one pair of transducers, the distance between which is erroneous.
