Sentences with phrase «sound pressure waves»

The researchers wanted to determine if the fish could sense sound pressure waves underwater, so they filled a long metal tube with water and placed a loudspeaker at one end.

Not exact matches

On the other hand, the fact that water is slightly compressible is what allows pressure waves, such as sound, to travel through, though this property has almost no effect on surface waves.
Waves of light or sound fired at an object tend to bounce off its surface like raindrops on an umbrella, collectively exerting a subtle nudge called radiation pressure that pushes the object away.
In the middle ear, pressure oscillations in the air are transferred via the tympanic membrane (eardrum) and one or three small bones (ossicles) to fluid movements in the inner ear, where the conversion of sound waves to nerve signals takes place.
There are four types of blast trauma injury: 1) primary injury caused directly by the pressure wave, which can travel through tissue at velocities close to that of sound in water, 2) secondary injury caused by objects put in motion by the blast, 3) tertiary injury caused by an individual thrown into motion by the blast and hitting surrounding objects, and 4) quaternary injury caused by burns, explosion - related injuries, illnesses and diseases not attributed to the other three blast trauma types.
This resulted in an ultrasonic pressure wave that can be detected as sound to give information about the cell's size and shape.
A sound wave is a pressure wave, so produces a force that can potentially counteract gravity.
Many of these technologies, including the marine vibrator — which conducts surveys using a steady pulse of low - pressure sound waves over a longer period — are «not that far away from industrial scale use,» Nowacek said.
When these laser pulses hit a blood vessel, for example, they cause a small increase in pressure that moves through the body like a sound wave and can be measured on the skin.
I built a work that exploits the phenomenon of sonoluminescence, in which extremely high pressure sound waves in liquids create tiny sources of electromagnetic energy.
Pressure from sound waves flexes and rotates the beam to create an electric signal that's processed to determine sound direction — the same way O. ochracea does.
That disturbance produces waves of high and low pressure traveling at about 760 miles per hour, which we experience as sound.
The NOAA team has set up several arrays of sensors, spaced hundreds of miles apart, that register slight variations in air pressure — a sign of a lengthy sound wave passing by.
If the sound is loud enough and at the right frequency, the pressure at the trough of the wave will be so low that the fluid will boil, producing microscopic bubbles.
When the high pressure front at the crest of the sound wave slams into these bubbles, they implode, and shock waves focus the energy of the implosion to a central region of atomic dimensions.
The change in pressure as the object outruns all the pressure and sound waves in front of it is heard on the ground as an explosion, or sonic boom.
Because sound waves have pressure, they can push very small objects, so a cell or nanoparticle will move with the sound wave until it reaches the location where there is no longer movement.
When opposing devices send out surface acoustic waves, they set up a grid of nodes where the sound pressure cancels out.
The pulses heated the nanoparticles, which disturbed the water around them, generating pressure, or sound, waves.
Sound waves and sonic booms are examples of pressure waves.
This is only briefly before the air expands due to latent heating to equalize the pressure (Pielke commented on these fast adjustment processes due to sound waves).
«Even the disturbances in the form of sound waves such as pressure waves in gases, liquids and solids may be harvested for powering nano - and micro devices of the future if these materials are processed and manufactured appropriately for this purpose,» Cagin said.
