Listening test scores of spatial attributes of the planar and spherical arrays for speech and noise bursts source signals. The signals presented are a high-quality reference HOA-based reproduction of order 32, Ambisonics of order N=1, BFBR with D=4, BFBR with D=12, and BFBR with D=73. The boxes show the interquartile range (IQR), for the 25 to 75 percentiles, and the median (red lines). 1.5×IQR (whiskers), and 95% confidence levels (notches). Outliers are marked by “+” [52]
