The purpose of the present paper is to measure the transfer matrix of acoustical, reciprocal elements of wave guides by using two microphones and several terminal tubes, by mean of the least mean square method. We apply this method for the case of a lateral chimney. The results are satisfactory, but the accuracy is not large enough to determine the anti symmetrical field in the chimney.
