When he left the Navy, Cassone began a 10-year experiment with sound waves
in his home garage, tweaking the frequency, time and exposure, Soriano said.

that was shaped into a pattern like the letter A, one foot past the acoustic metamaterial array.
The collaboration now includes some 1,000 astronomers from more than 50 institutions worldwide, and they're tackling a grand goal: measuring the faint imprint of cosmic sound waves
that reverberated throughout the universe during its first 380,000 years.
Dr Tom Hayward from the University of Sheffield and Professor John Cunningham from the University of Leeds have together come up with a completely new solution: passing sound waves
across the surface on which the wires are fixed.
It uses gentle mechanical force created by sound waves
to recover whole, unaltered cancer cells that can be used for further testing.
Potential licensees in the cell phone accessories industry are currently being targeted as candidates to eventually commercialize the Cross Sound Wave
on a worldwide basis.
So if gases can transmit sound waves
, couldn't an exploding spaceship make a noise that travels along with the gases emitted by the explosion?
In this method, nodularity is checked using an ultrasonic velocity measuring instrument, which measures velocity by sending and receiving sound waves
as they travel through a section of a casting.
In similar fashion, the speed of sound is also partly responsible for the rambling we hear, due to refraction-- the bending of sound waves
If, on the other hand, you want to create your own sound wave
, using your microphone, click on Create New and a Sound Object screen will appear (exhibit 2, below).
The transducer sends a pulsed sound wave
through a test sample that is submerged in water.

NDE instrument commissioned by the New Zealand company Carter Holt Harvey and developed by Industrial Research Limited in New Zealand is being used to measure log stiffness in the yard.
