VIRAL AUDIO DEBATES

Auditory Illusions are like magic tricks for your ears. They make you hear things that aren’t there or misinterpret sounds. Think of the famous “Yanny or Laurel” debate – two people hear completely different words from the same audio clip.

NOTE: 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. 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”. 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.”

According to colleague Dan Ariely PhD, our brains love patterns, sometimes too much, leading us to hear phantom sounds or misinterpret music lyrics. It’s a reminder that our senses are easily fooled, so don’t believe everything you hear.
