Fig. 8From: Loudness stability of binaural sound with spherical harmonic representation of sparse head-related transfer functionsBox plot of scores showing truncation and sparsity conditions at different SH orders, for loudness stability evaluation. Each box represents a different \((Q,\widetilde {N})\) condition. The box bounds the IQR divided by the median, and Tukey-style whiskers extend to a maximum of 1.5 × IQR beyond the box. The notches refer to a 95% confidence interval. a Test #3: \(\widetilde {N} = 10\). b Test #4: \(\widetilde {N} = 4\). c Test #5: \(\widetilde {N} = 2\)Back to article page
