Mapping out the structure of the inner ear.

There are no two human beings who are exactly alike. One of the funny quirks of evolution is that some of us can do things with our bodies we think are routine, but are impossible for others.

Some people can wiggle their ears, others can't. Some can wiggle their nose like Samantha from "Bewitched" while others just look really silly when making an attempt.

Not everyone can lick their elbow but most wouldn't attempt to do so in public.


A Twitter user named Massimo dropped some knowledge about a skill that not everyone has and even fewer discuss: ear rumbling.

Those of us who can do it know exactly what it is, while it's a mystery to those who cannot.

People who can ear rumble have the ability to control the tensor tympani, a muscle within the ear. Contracting the muscle creates a rushing, rumbling sound that, if flexed enough, can drown out a significant amount of noise.

This can be useful when someone is saying something that you don't want to hear but don't want to be rude and cover your ears. It can come in real handy if someone is about to spoil your favorite TV show or if you live with someone who can't stop nagging.

Some people cannot voluntarily create the rumbling sound but hear it when they let out a large yawn.

There's a Reddit sub-forum just for ear rumblers with over 60,000 people. Here's how some of them get rumblin'.

"I just squeeze the muscle in my ears I guess," — melvinthefish

"When I flex and hold whatever I'm manipulating to do that, I get my rumble," — ttywzl

"I get a mild rumble just doing the usual flex, but i can make it a bit louder by bringing my top lip up to my nose," — Willmono7

"The best way I can describe it is I 'squint my ears,'" —SteeleIT

The muscle exists to mask-low frequency sounds so we can focus on those at a higher frequency. It also works to mute sounds we create ourselves such as eating potato chips or coughing. It's a way that helps us from becoming annoyed with our own bodies.

Unfortunately, the muscle has a rather slow reaction time so it cannot prevent us from hearing loud sudden noises like a gunshot or a book slamming on the ground.

Massimo's tweet caused quite a stir on the platform.

Although scientists have known about ear rumbling since at least the 1800s, there doesn't appear to have been too much research on the topic. We know that some can rumble and others cannot, but it's unclear how it breaks down percentage-wise or if it's more prevalent in certain groups.

The good news is that the word is starting to get out and people who've been rumbling all their lives suddenly don't feel so alone.

For Tom Williams, a chiropractor from Chicago, every day is bring your son to work day.

At his family-based practice, which he runs along with his wife, Lauren, Tom is used to having kids in the office. In fact, his new son, Oliver, was nearly born there — Lauren was staked out at the front desk when she first went into labor.

After some recovery at home, the couple wanted to get the business back up and running again, but as parents and entrepreneurs, it was a challenge. Tom loved helping take care of his wife and new son, but wanted to get back to taking care of his patients too.

So together, Tom and Lauren came up with a pretty cool idea.

A few days per week, Oliver comes to the office where he splits time at Mom's desk and strapped to Dad's chest.

Tom was photographed by a patient earlier this month wearing a contented Oliver while casually giving an exam, and people across the internet are absolutely loving it.

"Just seeing Dr. Tom, he's such a calm doctor and such a loving person and I thought he was going to take the baby off, but he said, 'Nope the baby's sleeping' and started adjusting all of us,'" the patient who first shared the story, Genia Rackos, told ABC News. "I think he shows a really good example of what work-life balance is. He wears his baby with pride and it stands for everything he's about."

"I wear him in the office because it’s a chance for me to strengthen our bond," Williams says. "I truly love wearing him and that’s why we do it all the time. "

Tom is quick to point out the emotional and biological benefits of baby-wearing. But there's something even bigger at play here.

It's not uncommon to see a waitress taking orders with a sleeping baby across her chest or a small bassinet tucked in the corner of a cubicle in some corporate office.

In fact, companies are slowly growing more and more comfortable letting parents bring their babies to work.

Here's the catch: Figuring out what to do with baby during the day usually winds up being the mom's problem. A survey done by Parenting.com found that moms often wind up doing the lion's share of caretaking.

But the tide is turning, with more and more dads feeling empowered to take on a larger, if not the starring, role in raising the next generation of babies.

Guys like Williams are leading the charge, proving what moms have known for years: You can be a great parent and be good at your job, but no one ever said it'd be easy.
