Measurements and Visualization of Sound Intensity Around the Human Head in Free Field Using Acoustic Vector Sensor

Abstract

This paper presents measurements and visualization of sound intensity around the human head simulator in a free field. A Cartesian robot, applied for precise positioning of the acoustic vector sensor, was used to measure sound intensity. Measurements were performed in a free field using a head and torso simulator and the setup consisting of four different loudspeaker configurations. The acoustic vector sensor was positioned around the head with a 5-cm step. Sound intensity was measured in 277 points. For every step, three orthogonal sound intensity components were calculated. Pure tones of frequencies: 250, 1000, and 4000 Hz were applied to analyze the acoustic field. Obtained results were used to provide visualizations of sound intensity distribution around the human head. The tool developed for this purpose utilized three-dimensional sound intensity measurements and visualization techniques.
