Auditory illusion

[2] Humans are fairly susceptible to illusions, despite an innate ability to process complex stimuli.

When someone is experiencing an auditory illusion, their brain is falsely interpreting its surroundings and distorting their perception of the world around them.

[7] Many auditory illusions, particularly of music and of speech, result from hearing sound patterns that are highly probable, even though they are heard incorrectly.

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.

[15] According to Purwins,[16] auditory illusions have been used effectively by the following: Beethoven (Leonore Overture), Berg (Wozzeck), Krenek (Spiritus Intelligentiae, Sanctus), Ligeti (Études), Violin Concerto, Double Concerto, for flute, oboe and orchestra), Honegger (Pacific 231), and Stahnke (Partota 12).
