Figure 22. — We placed two monochromatic sound sources at the center of an anechoic chamber and placed our SoundCompass in eight different positions within this chamber (a). The polar graphs generated at each position (b) were used as the input in our data fusion algorithm to obtain a probability map (c). The localization errors for Sound Source 1 and Sound Source 2 were 10 cm and 2.2 cm, respectively. (a) Anechoic chamber setup: two sound sources and one SoundCompass in eight different positions; (b) the resulting polar graphs are displayed here with respect to their positions; (c) the generated probability map located the two sound sources with an accuracy of 10 cm and 2.2 cm.
