Seashore

overlapping chatter

It's not just unpleasant sounds like that that do it.

And so one of the tools that we can use to sample the oceans is acoustics, or sound waves.

Audio Waveform Monitor

Ultrasonic Bath

You can hear the sound of ocean.

I can pick it up, touch it.

We're moving, obviously, to the era of the tricorder.

(Video sound)

On the right hand side, you see an ultrasonic transducer.

Now, it's important to remember that you're only hearing the human audible parts of dolphin sounds, and dolphins make ultrasonic sounds, and we use special equipment in the water to collect these sounds.

I'd like you to have an ultrasound.

Light and sound travel in waves.

So the first one is in the brain.

And I will just rock it really hard here again.

The good news is that we're actually born smiling.

The sea can be heard from here.

And when you rock the chair, or when you sit on the chair, you can hear the sound.

Alright.

I'm going to use a device from a company called Mobisante.

Can you hear the noise of the waves on the beach?

So, let's fire it up and see what it does. So let's play a 550 herz frequency and watch what happens.

It's actually traveling in all directions, and the Rubens' tube's a little like bisecting those waves with a line, and the flame table's a little like bisecting those waves with a plane, and it can show a little more subtle complexity, which is why

(Laughter)

That's shown down here.

It's a color sensor that detects the color frequency in front of me (Frequency sounds) and sends this frequency to a chip installed at the back of my head, and I hear the color in front of me through the bone, through bone conduction.

We got tactical smart missiles, phasedplasma pulse rifles, RPGs, we got sonic electronic ballbreakers!

It's actually emitting ultrasound low level ultrasound that's about 100,000 vibrations per second.

And on the y axis is the loudness of average ambient noise in the deep ocean by frequency.

Nothing was to be heard except the sound of the waves.

I'm sick to death of this old cell phone.

The question was, where from?

What that means is they're both explosions in lay terms but a deflagration is where the wave, the shock wave travels at the speed of sound.

It is an amazing tool called astroseismology where we can detect sound waves in the atmospheres of stars.

And so in this example, a census scientist took out two ships.

Why is this important? Because this is so much more sensitive.

So I went in for an ultrasound.

With every crash of every wave, I hear something now.

like wind in the trees, water in a stream, waves at the ocean shore, movement of the Earth.

Now you are listening to a recording made by Chris Clark, 0.2 miles away from a humpback.

I wonder why it is that the sound of waves is so pleasant to the ear.

like clocks, electromagnetic waves, and even music.

And after the recombination, baryons, the visible material, falls into those potential wells.
