dc.description.abstract-translatedThe paper deals with numerical modeling of acoustic field produced by a commercial loudspeaker. The goal is to obtain the directional characteristics of the device. The continuous mathematical model is derived from the physical laws and is considered for the ideal fluids with properties of a perfect continuum. The model of the loudspeaker in the axial symmetry (2D) is described by the Helmholtz differential equation for harmonic acoustic field and for the correct solution the appropriate boundary conditions and material properties are also defined. The data obtained during the measurement must be used to implement the model. In our case, there was the fundamental knowledge of the velocity of the diaphragm oscillation for the selected frequencies.en
