Okay, so let's talk a little bit about ultrasound, the force of ultrasound.

From here to here is the wavelength of sound.

What about ultrasound?

Shree Bose Hi everyone. I'm Shree Bose.

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

Play with waves and vibrations

So I went in for an ultrasound.

This is much sharper than an ultrasound would be.

You know all about imaging, right, ultrasound imaging.

Because just that soil could make the acoustic difference.

So the ultrasonic transducer emits basically an ultrasonic beam that focuses inside the phantom.

Those waves have frequencies in infrasound domain, the sound actually nobody knows, domain.

Sometimes it's also because of the sonogram.

This is surf.

These have similar wave forms. They're both sustained instruments.

Radio could carry sound without wires.

And you're going to hear an undulation between the sound.

Evan Grant demonstrates the science and art of cymatics, a process for making soundwaves visible. Useful for analyzing complex sounds , it also makes complex and beautiful designs.

It's acoustic vibrations in the air, little waves of energy in the air that tickle our eardrum.

Well, the obvious way to measure the speed of sound is to bounce sound off something and look at the echo.

So the first sonication is at lower energy.

So she elected to undergo a focused ultrasound procedure in 2008.

So you can change the intensity, the frequency, the duration, the pulse shape of the ultrasound to create anything from an airbrush to a hammer.

By playing the string, the string vibrates and produces a sound wave.

We call this instance of injecting the energy, we call it sonication.

She's a veterinarian, so she's seen lots of ultrasounds.

One strategy is if your call's down here, and the noise is in this band, you could shift the frequency of your call out of the noise band and communicate better.

Maybe if I hit the side wall it will bounce around the room.

So this idea of harnessing focused ultrasound to treat lesions in the brain is not new at all.

This is an MR suite with a focused ultrasound system.

They were the first to be treated by focused ultrasound.

The impacts of marine acoustic technology on Antarctic organisms were given further examination.

The Committee will provide an update on marine acoustic technology in 2006.

So as Susan Boyle was saying that, 80,000 live audience sang together.

I made that up because I just wanted to put up a slide of the Mola mola fish.

Yeah, the wavy hair, the blue eyes it was really something.

Sputnik wasn't a technical loss, but it was a prestige loss.

We can detect sound waves in the atmospheres of sun like stars.

So anytime I talk, you'd see it on the screen.

Okay. On the other hand by placing your finger in a different position on the fingerboard it changes the string length, that changes the frequency of the sound wave.

Bear in mind this was an ultrasound, so it would have been moving images.

But ultrasound can be shaped to be anything in between, because it's a mechanical force.
