Editing Human echolocation (section)

==Overview==
Many blind individuals passively use natural environmental echoes to sense details about their environment (passive echolocation); however, others actively produce mouth clicks ([[palatal click]]) and are able to gauge information about their environment using the echoes from those clicks (active echolocation).<ref>{{Cite journal |url=http://www.psychologicalscience.org/index.php/publications/observer/2015/december-15/using-sound-to-get-around.html |title=Using Sound to Get Around |publisher=Association for Psychological Science |issue=10 |journal=APS Observer |volume=28 |access-date=2016-04-22 |date=2015-11-25 |last1=Thaler|first1=Lore}}</ref> Both passive and active echolocation help blind individuals sense their environments.

Those who can see their environments often do not readily perceive echoes from nearby objects, due to an echo suppression phenomenon brought on by the [[precedence effect]]. However, with training, sighted individuals with normal hearing can learn to avoid obstacles using only sound, showing that echolocation is a general human ability.<ref name=":1">{{Cite journal |last1=Wallmeier|first1=Ludwig |last2=Geßele|first2=Nikodemus |last3=Wiegrebe|first3=Lutz |date=2013-10-22 |title=Echolocation versus echo suppression in humans |journal=Proceedings of the Royal Society of London B: Biological Sciences |volume=280 |issue=1769 |pages=20131428 |doi=10.1098/rspb.2013.1428|issn=0962-8452|pmc=3768302|pmid=23986105}}</ref> John Levack Drever refers to echolocation in humans an example of panacusi loci,<ref>{{Cite book |last=Drever |first=John Levack |chapter=Aural diverse spatial perception: From paracusis to panacusis loci |date=2024-11-11 |title=The Routledge Companion to the Sound of Space |pages=164–179 |url=https://scholar.google.com/citations?view_op=view_citation&hl=en&user=YnfhoB4AAAAJ&sortby=pubdate&citation_for_view=YnfhoB4AAAAJ:g3aElNc5_aQC |access-date=2025-02-08 |publisher=Routledge}}</ref> spatial hearing that exceeds the prescribed normative mode.
