Auditory distance localization error varies dramatically across studies.

Evidence

Zahorik et al. (2005) also summarized the directional blur in different studies. In some cases, the blur was only 5–25% of the source distance, while in some other studies the error range was up to 60% to the distance to the source. Higher errors are obtained especially with distant sources. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1532
