✦ Synopsis

The computer-aided method for determining the directional characteristics of a loudspeaker system is presented. Considerations were carried out for the three-way loudspeaker system assuming the transition of both the structure of crossover networks and location of loudspeakers in the front panel of the enclosure. The directional characteristics of respective loudspeakers were determined on the basis of measurement data. The calculations of directional characteristics for some specific frequencies from the cut-off region of crossover networks were performed. A comparison of directional characteristics obtained in calculations and measurements was carried out and an angle between the direction of maximal radiation and the symmetry axis of the loudspeaker system has been used as a criterion of compatibility of results.

1 Introduction

An electrical signal fed to the input of a loudspeaker system, having been changed to an acoustic signal, reaches an observation point in the radiation area of the system. During the process the signal is transmitted by crossover 179

An idealized mathematical model of adaptive-system behavior, using conventional economic decision-theory assumptions, is stated. The data-processing capacity of this model is analyzed, revealing that it would be rapidly overwhelmed by even moderate complexity. To circumvent this difficulty, a practi
