The main goal of this research study was to measure and visualize sound field intensity distribution in and without presence of the human head model. Measurements were performed in the anechoic chamber with the 5 cm grid. Experimental setup consisted of a multitone generator, two loudspeakers, human head model, intensimetric probe, the Cartesian robot applied for precise positioning of the acoustic sensor, and an analyzer. Based on the collected data a sound field visualization was created in the form of colored maps and arrows illustrating pressure and intensity vectors at a given point in the presence of the artificial head, as well as without this obstacle plus the difference resulted from the both mentioned conditions occurrence. A thorough analysis of the results obtained and conclusions follows the experiments presented in the paper.
