Editing Auditory illusion (section)

== Causes ==
Many auditory illusions, particularly of music and of speech, result from hearing sound patterns that are highly probable, even though they are heard incorrectly. This is due to the influence of our knowledge and experience of many sounds we have heard.<ref>{{cite book | last=Deutsch| first=D.| title=Musical Illusions and Phantom Words: How Music and Speech Unlock Mysteries of the Brain | year=2019  | url=https://global.oup.com/academic/product/musical-illusions-and-phantom-words-9780190206833| publisher=Oxford University Press| lccn=2018051786| author-link=Diana Deutsch|isbn=9780190206833 }}</ref> In order to prevent hearing echo created by perceiving multiple sounds coming from different spaces, the human auditory system relates the sounds as being from one source.<ref>{{Citation|last=Deutsch|first=Diana|title=Auditory Illusions|url=http://dx.doi.org/10.4135/9781412972000.n56|encyclopedia=Encyclopedia of Perception|year=2010|location=Thousand Oaks, CA|publisher=SAGE Publications, Inc.|doi=10.4135/9781412972000.n56|isbn=978-1-4129-4081-8|access-date=2020-11-08}}</ref> However, that does not prevent people from being fooled by auditory illusions. Sounds that are found in words are called embedded sounds, and these sounds are the cause of some auditory illusions. A person's perception of a word can be influenced by the way they see the speaker's mouth move, even if the sound they hear is unchanged.<ref>{{Cite web|url=https://www.hear.com/useful-knowledge/auditory-illusions/|title=Auditory Illusions: How your ears can be fooled|website=hear.com|language=en-US|access-date=2019-04-19}}</ref> For example, if someone is looking at two people saying "far" and "bar", the word they will hear will be determined by who they look at.<ref>{{Cite web|url=https://www.iflscience.com/brain/do-you-hear-what-i-hear-amazing-auditory-illusions-explained/|title=Do You Hear What I Hear?
