The Language You’re Fluent in — but Forgot How to Hear | Louis VI | TED
字幕 (313 片段)
We humans have stopped listening.
Wow, you all really listen to that.
(Laughter)
But it's true. There's a language out there
that we all know how to communicate really quite well,
but we’ve tuned out of.
One we’re innately fluent in, yet forgotten how to hear.
I truly believe the key to solving many of our crises as humans
is relearning to listen to this language.
What I'm talking about is the sounds of nature.
I want to take you all somewhere real quick, if that's alright.
I want you to close your eyes
and make a mental note of how you feel right now.
You can be happy from the week, stressed.
It is a Wednesday in the middle of the week.
Charmed already from my London accent
or annoyed by it.
Just be honest.
Now close your eyes and open your ears.
(Nature sounds)
Mmm...
How do you feel?
Different, right? A bit better, maybe slightly more relaxed.
I saw quite a few smiles playing across people's faces.
You were just transported to West Papua.
That beautiful melody was a hooded butcherbird,
which, believe it or not, is carnivorous.
Didn't think predators could sing like that, right?
(Laughter)
So what's happened?
Is it that you're all nature geeks like me?
Maybe.
But it's probably because we're all evolutionarily hardwired
to nature's sonic language.
See, we're so hardwired to it,
so much so, the birdsong, choruses of birdsong,
the percussion of insects, the symphony of amphibians
has all been shown scientifically
to trigger your parasympathetic nervous system,
aka make you feel relaxed.
You probably also noticed you were in a forest
and a tropical one at that.
It might seem obvious to mention,
but that was just from you using your ears.
Look at you flexing your fluency already.
It's possible the birdsong makes us feel relaxed
because it's been ...
a genuine signal from Mother Nature that there's no predators around.
But it can't be all relaxing.
(Lion roars)
Hearing this from an unseen lioness near you in the dark,
trust me, triggers a cascade of fear.
But one that's also practical and proportionate.
Eerie, unusual silence does the same thing.
It's no wonder that we're seeing a rise in anxiety in cities.
We may be unknowingly subjecting ourselves to an evolutionary stress.
See, nature sound does something to us.
It's often hard to put into words, true,
but our nervous system understands it like a remote control.
Blindfold on, I bet I could put any one of you in a biodiverse environment,
and you'd be able to tell me if it was dawn.
(Nature sounds)
The middle of the day.
