摘要

The theoretical basis for the identification procedure for the installation element has been shown in part I. This method is based of the generalized Helmholtz model. The identification procedure has to determine, on the basis of the experiment, four independent transmission matrix elements. In this part the use of worked-up method is shown. The method may be used when the object is mounted in the installation, as well as on the specially designed stand outside the installation. On the stand outside the installation the acoustic speaker have been used as a source of pressure pulsation wave. The basic frequency for the identification experiment should be the same as the basic frequency in the installation, or a "white noise" can be used.
