Abstract

Measurements and visualization of sound intensity around a human head are presented in this paper. The sound intensity field was obtained by means of a Cartesian robot that was applied to precise positioning of the acoustic vector sensor. Measurements were performed in the free field using a head and torso simulator and a configuration of either one, two, or four loudspeakers. The acoustic vector sensor was positioned around the head with 5 cm step. Sound intensity was measured in 277 points. During every step the three orthogonal sound intensity components were calculated. Tonal signals for frequencies: 250, 500, 1000, 2000, 4000, and 8000 Hz were applied. Obtained results were used to prepare visualizations of sound intensity distribution around the human head.
