Seashore

The sound of the ocean.

The sound of the ocean.

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

Extace Waveform Display

Ultrasonic Bath

You can hear the sound of ocean.

The wind and and the waves... (whoosh)

I can pick it up, touch it.

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

(Video sound)

It's like an ultrasound.

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

I'll scream, Takemoto

I had r d work it up. Sends out a highfrequency pulse records the response time for mapping an environment.

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.

We've got some kind of RF interference with the the fathometer.

The frequencies are ultrasonic. Simple noise cancellation won't work.

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.

And a highfrequency generatorreceiver.

The sonographer said four months.

No, it's ultrasonic, so you wouldn't be able to hear it. The frequency's too high.

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.

And all the time there's the sound of the sea.

That frequency triggers the explosion.

(Laughter)

That's shown down here.

Prepare Agent Francis for the ultrasound.

Can't beat the sound of the waves, ah?

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

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!

Electroconductive gel for the ultrasound.
