"Laurel" exists in the lower frequencies and "Yanny" exists in the higher frequencies.
The White House hasn't escaped the "Laurel/Yanny" debate after it posted a video of US President Donald Trump and staff weighing in on the social media storm.
'Definitely Laurel, ' Deputy Press Secretary Raj Shah agrees.
"When there is more energy towards the mid and higher frequencies, people tend to hear "Yanny". In a recent Twitter poll, 47% of people heard Yanny while 53% heard Laurel. Some hear the clip as "laurel", while others hear it as "yanny".
"Clearly you're getting your information from CNN because that's fake news - all I hear is Yanny", Sanders deadpans. All I hear is yanny.
The White House had some fun Thursday with the president's infamous Twitter flub - while rounding up West Wing opinion on an audio clip that has hijacked the Internet.
The video ends with a cameo by President Trump who delivers the punchline.
