TikTok audio illusion divides opinion when listeners hear ‘green needle’ or ‘brainstorm’

Viral audio clip that sounds like ‘green needle’ or ‘brainstorm’ leaves TikTok listeners astounded – so which one do you hear?

  • TikTok clips surprised listeners after hearing two words from the same audio
  • In images, people see one of two sentences, ‘brainstorm’ or ‘green needle’
  • It was posted on TikTok this week by Emily Sophie, believed to be from Wales

An audio clip that can be heard as two different words has amazed social media users.

The sound, which first went viral in 2018 and has now surfaced on TikTok, can be heard as the phrase ‘green needle’ or the word ‘brainstorm’.

The clip plays while both words flash on the screen. The one hearing the individual would change depending on which word is read on the screen and therefore thought about.

It was posted in one clamp by Emily Sophie, believed to be based in Wales earlier this week and has since been loved more than 112,000 times, and is also widely shared on Twitter.

The science behind it! How it is possible to switch between ‘green needle’ and ‘brainstorm’

While some listeners struggle to hear both words, many successfully pick up ‘green needle’ and then ‘brainstorm’.

Professor Valerie Hazan from University College London told it Huffington Post Last year, when the phenomenon first surfaced, people’s hearing and brain function may ‘hook up’ to different sounds.

She said, “The reason a person can see their perception switch without explanation can also mean that our ears and brains are riveted to the different acoustic pattern than they were holding.”

It has previously been confirmed that the audio actually says brainstorming.

Listeners said they were stunned by the trick, which asks them to think of one of the words before the audio seemingly changes to reflect their choice.

In her clip, Emily asks viewers to listen to the same audio twice, once reading a caption that reads ‘brainstorming’ and again looking at the word ‘green needle’.

“You only hear the word you read,” her third caption suggests.

Shocked by the illusion, one person wrote, “I’ve tried it a few times. Was blown away until I read the green needle but heard a brainstorm. So now I don’t know if I’m too smart for it or what. YOU?’

Another said, “I wonder how I interpret almost everything people say to me, do I just hear what I want to hear?”

A third person added, “You can also say” brain needle. ” This is confused. ‘

The clip even caught the attention of several well-known faces, including actor and comedian Ricky Gervais, who retweeted the footage alongside the caption, “It also works if you close your eyes and just think about the one you want to hear.”

Despite the widespread confusion, this is not the first time the audio trick has been shared online.

It appeared in a 2018 Reddit post, with that version featuring a toy that seemed to say one of two words when activated.

It was previously confirmed that the audio actually says brainstorming.

Professor Valerie Hazan, an expert in speech, hearing and phonetic science at University College London, told the Huffington Post last year that the reason behind the trick’s success is that our minds can ‘stick’ to the second perceived acoustic pattern.

“The reason a person can see their perception switch without explanation can also mean that our ears and brains are riveted to the different acoustic pattern than they were holding before,” she explained.
