Oversized pinna cues significantly improved localization accuracy only at wide reference angles.

Evidence

Since the difference between normal and enhanced cues was the essence of the research question, the cue-type effect was further explored by conducting two planned comparisons, N vs. T and N vs. W (across the two reference angles). These analyses showed a significant difference between N and W cues (mean MAA difference of around 10°, p = 0.0005) and a non-significant difference between N and T cues (mean MAA difference of around 5°, p = 0.06). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3120

• QUESTION: Worth chasing: does enhanced outer-ear detail help only where front-back or large-angle ambiguity dominates, suggesting the cues matter for resolving spatial ambiguity rather than improving acuity broadly?
