SOME people can hear a strange rumbling in their ears when they tighten their muscles.
A Twitter science enthusiast named Massimo went viral after tweeting about a muscle in your cleats that can make a “roaring” sound.
To create the sound coming out of your ear, you have to contract the muscle — but most people can’t.
Just squeeze your face really tight, including your eyes, and see if you can hear a low, thunder-like rumble.
Massimo wrote in February 2020: “A portion of the human population can voluntarily control the tensor tympani, a muscle in the ear.
“The contraction of this muscle creates vibrations and sounds. The noise is usually described as a rumbling sound.”
The phenomenon has been known since the 19th century.
The muscle in question, the tensor tympani, is thought to muffle loud sounds like the sound of one’s own chewing or the clap of thunder.
When contracted, the muscle changes the shape of the eardrum to dampen vibrations and protect the ear.
Some people can do this manually, creating a rumbling noise.
How to make the ‘roar’ sound
- Try tensing all your facial muscles and closing your eyes
- This action can also tighten a muscle in your inner ear and create a rumbling sound
- Only some people can do that, so if you can’t hear anything, you might be out of luck
- You can also replicate the sound by tensing another muscle near your ear
- For example, try clenching a fist and squeezing it tightly while holding it to your ear
“It sounds like a big thunderstorm to me,” one Twitter user wrote in response to Massimo’s post.
“Thunder forever rolls quietly across the sky, with only tiny bolts of lightning that don’t leave the clouds.”
Others expressed surprise that not everyone could make the strange noise.
“I can do it! woo! Didn’t know it was an unusual thing. I have to close my eyes though,” wrote one user.
Another said: “I didn’t know what that was but I always could. Cool, thanks for this post! I learned something new.”
Other people haven’t had quite as much luck producing the sound.
One tweeted, “I’m not one of those people and I feel like what it must be like for color blind people to be privy to the normochromatic discussion.”
The discussion brings back memories of “the dress” that sparked a worldwide online debate in 2015.
It was a photo posted online of a dress that some people saw as gold and white, while others saw it as black and blue.
The dispute became so famous that it has since been used by neuroscientists in the study of color perception.
