Sound localization is best for frontal sounds and at low and high frequencies

Evidence

In summary, we see similar results from Mills as we observed from Stevens and Newman: Sound localization is best when sounds are in front of the body. Further, sound localization abilities are very good at low and high frequencies. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1500
