Compared with KEMAR's measured HRTFs available in the CIPIC database, the mean spectral mismatch on a linear frequency scale up to 14 kHz was 2.3 dB; this was better than the 3.1 dB mismatch between KEMAR's left- and right-ear measured HRTFs. FDTD simulations were then run to clarify acoustic consequences of smoothing away facial features, morphing the head shape towards a sphere, and either exaggerating or reducing the degree of concavity/convexity in the folds and cavities of the pinna.
