Do You Hear ‘Brainstorm’ Or ‘Green Needle’?


Want a new mind blower. Hear you go!
Listen to the audio below and think of either “Brainstorm” Or “Green Needle.”
What do you hear?

Or even feel free to think of “Brain Needle” Or “Green Storm.”

The whole thing is supposed to function on the same principles as the Yanny and Laurel puzzler: A change in pitch and individuals’ sensitivities to certain pitches push them into one “camp” or another.

The word “brainstorm” is stronger in lower frequencies, and “green needle” is stronger in higher ones. It’s also important that the audio quality not be particularly crisp.

In this case, apparently, the selections are so closely balanced along the pitch line that a thought might be enough to nudge a listener one way or the other — as long as the brain is “primed” to think of the options.
