Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

This is Scientific American's 60-second science. I'm Christopher in Taliatta.

Certain concert venues, like Boston's Symphony Hall, are known to beautifully reflect the sounds of an orchestra.

And it turns out there's a similar process at play in your cochlea, deep inside your ear,

where a tiny, bony cavity houses the organ that allows you to hear.

It's like its own tiny little acoustics chamber, if you will.

So anything and everything you hear is going into your ear and then going into this little bony chamber.

Mike Gordon, a psychologist at William Patterson University in New Jersey.

But while studying this process, he also found there's

actually a lot of variability in the way people hear. Some frequencies can appear tens of

decibels louder or quieter than average based on the resonant properties of a person's skull.

We were shocked. My first version of the draft had exclamation points all over the place,

but we eventually removed those from the final copy.

First, Gordon's team gave 30 volunteers a hearing test, the standard type where different

frequencies of tones are played at varying loudness.

Then they did a bone conduction hearing test, where vibrations are transmitted directly onto

the skull from behind the ear.

Finally, they projected white noise like this
