Elliptic's ultrasound technology uses sound waves and microphones to detect movement, similar to how radar detects objects.
Another line, the GE Profile, automatically streams water into containers of any size using sound waves.
However, the sound waves themselves become attenuated in different ways as they travel through different people.
This allows it to vibrate in sympathy with sound waves, like the diaphragm in a conventional microphone.
Electric currents could convey sound along a wire if they undulated in accordance with the sound waves.
It takes sound waves in the environment and transforms them into nerve impulses to the auditory nerve.
And second, they react more slowly than a small audience, because of the sheer physics of sound waves.

As the sound waves reverberate, the sensors register them and computers interpret the findings to determine promising drilling sites.
Seismic specialists like CGGVeritas and Schlumberger's WesternGeco are coming up with new ways to bounce sound waves off rocks.
Soil is a highly attenuating material, meaning that it is difficult for sound waves to travel far in it.
The Optigan, or optical organ, plays samples from a transparency with sound waves printed on it, like the grooves on a record.
The key to the R-series' superb sound reproduction is the precise control of the inevitable vibrations created by sound waves.

Spreading the area of air pressure over the jet staggers the sound waves and decreases the intensity of the boom.
Astroseismology is performed when scientists examine the sound waves generated beneath the surface of the star to determine its size.

Question the audiophile about the best brand of headphones and you first learn how sound waves are registered by our tympanic membranes.
Conventional loudspeakers spew a shotgun spray of sound waves in all directions.
Sound waves were also used to visualize the rising plumes of gas.

That allows bigger pores, which help to trap and disperse sound waves.

Since the esophagus passes close behind your heart, the transesophageal transducer can produce better images than can sound waves transmitted through your chest.
But researchers quickly found out that the mathematics behind bending these light waves, called transformation optics, could also be applied to sound waves.
In other words, the boundary between the supersonic and subsonic regions would do for sound waves what the event horizon does for light.
The exact size and placement of the holes on each sheet, and the spacing between the sheets, has a predictable effect on incoming sound waves.
That is because, like light waves, sound waves can be focused.
ECONOMIST: Thermal treatments of cancer are remarkably effective
They then compressed and decompressed the gas, which generated sound waves.
Preliminary reports ruled out that seismic sound waves created by oil exploration in that stretch of sea could have killed the birds, the environment ministry said.
Just as seismic waves moving through Earth provide information about our planet's insides, so sound waves travelling through a star carry information about its inner workings.
Set the company's iPhone-sized speaker on a desk, coffee table or even a surfboard and it transfers sound waves into that material -- creating an on-the-fly subwoofer.
As you can see from the picture I got a little bit of clipping, but I wanted the sound waves to be as loud as they could.

"Inside stars it's a very noisy environment, and that noise sets up sound waves that travel all the way through the star, " said Birmingham astrophysicist Prof Yvonne Elsworth.
BBC: Exoplanet Kepler 37b is tiniest yet - smaller than Mercury
Behind the deep aluminum accents, the unique curvature of the unit goes beyond aesthetics with non-parallel walls that prevent the cross-cancellation of sound waves and produces more natural sound.
