"Yanny or Laurel" is an auditory illusion which became popular in May 2018, in which a short audio recording of speech can be heard as one of two names. 53 percent of over 500,000 respondents to a Twitter poll reported hearing a man saying the word "Laurel", while 47 percent reported hearing a voice saying the name "Yanny". Analysis of the sound frequencies has confirmed that both sets of sounds are present in the mixed recording, but some users focus on the higher frequency sounds in "Yanny" and cannot seem to hear the lower sounds of the word "Laurel". When the audio clip is slowed to lower frequencies, the word "Yanny" is heard by more listeners, while faster playback loudens "Laurel".
