Yanny or Laurel is an auditory illusion that became popular in May 2018, in which a short audio recording of speech can be heard as one of two words.[1] 53 percent of over 500,000 respondents to a Twitter poll reported hearing a man saying the word “Laurel”, while 47 percent of people reported hearing a voice saying the name “Yanny”.[2] Analysis of the sound frequencies has confirmed that both sets of sounds are present in the mixed recording,[3] but some users focus on the higher-frequency sounds in “Yanny” and cannot seem to hear the lower sounds of the word “Laurel”.
