The Language You’re Fluent in — but Forgot How to Hear | Louis VI | TED

00:08

We humans have stopped listening.

00:12

Wow, you all really listen to that.

00:14

(Laughter)

00:15

But it's true. There's a language out there

00:17

that we all know how to communicate really quite well,

00:19

but we’ve tuned out of.

00:21

One we’re innately fluent in, yet forgotten how to hear.

00:24

I truly believe the key to solving many of our crises as humans

00:28

is relearning to listen to this language.

00:30

What I'm talking about is the sounds of nature.

00:34

I want to take you all somewhere real quick, if that's alright.

00:37

I want you to close your eyes

00:39

and make a mental note of how you feel right now.

00:42

You can be happy from the week, stressed.

00:44

It is a Wednesday in the middle of the week.

00:46

Charmed already from my London accent

00:48

or annoyed by it.

00:49

Just be honest.

00:50

Now close your eyes and open your ears.

00:54

(Nature sounds)

01:12

Mmm...

01:14

How do you feel?

01:16

Different, right? A bit better, maybe slightly more relaxed.

01:20

I saw quite a few smiles playing across people's faces.

01:23

You were just transported to West Papua.

01:25

That beautiful melody was a hooded butcherbird,

01:28

which, believe it or not, is carnivorous.

01:30

Didn't think predators could sing like that, right?

01:32

(Laughter)

01:34

So what's happened?

01:36

Is it that you're all nature geeks like me?

01:40

Maybe.

01:42

But it's probably because we're all evolutionarily hardwired

01:45

to nature's sonic language.

01:48

See, we're so hardwired to it,

01:50

so much so, the birdsong, choruses of birdsong,

01:55

the percussion of insects, the symphony of amphibians

01:57

has all been shown scientifically

02:00

to trigger your parasympathetic nervous system,

02:02

aka make you feel relaxed.

02:04

You probably also noticed you were in a forest

02:06

and a tropical one at that.

02:09

It might seem obvious to mention,

02:10

but that was just from you using your ears.

02:13

Look at you flexing your fluency already.

02:16

It's possible the birdsong makes us feel relaxed

02:20

because it's been ...

02:23

a genuine signal from Mother Nature that there's no predators around.

02:27

But it can't be all relaxing.

02:29

(Lion roars)

02:33

Hearing this from an unseen lioness near you in the dark,

02:36

trust me, triggers a cascade of fear.

02:39

But one that's also practical and proportionate.

02:42

Eerie, unusual silence does the same thing.

02:45

It's no wonder that we're seeing a rise in anxiety in cities.

02:49

We may be unknowingly subjecting ourselves to an evolutionary stress.

02:55

See, nature sound does something to us.

02:57

It's often hard to put into words, true,

03:01

but our nervous system understands it like a remote control.

03:05

Blindfold on, I bet I could put any one of you in a biodiverse environment,

03:08

and you'd be able to tell me if it was dawn.

03:11

(Nature sounds)

03:17

The middle of the day.
