The content discusses the fundamentals of acoustics, focusing on sound refraction, the anatomy of the ear, and how sound ...

The machine can send sound waves at frequencies above the range of human hearing through the water as it flows through a pipe. The researchers have been able to kill off 99 percent of organisms ...

Sound waves travel through different types of matter, including liquid water. Importantly, the movement of ocean water can greatly affect how sound waves travel from one point to another.

They then played 1,590Hz sound waves from the speaker array to glide the ball through a pre-planned path while microphones detected feedback known as a scattering matrix as it bounced off the ball.

Ultrasound waves are longitudinal waves just like sound waves, and they cannot pass through a vacuum. ... Calculate the depth of water if the speed of sound in water is 1 500 m/s. Answer.

Similar to an ocean wave, sound waves are created by vibrations or movement in a given medium. When the wave is in the ocean, the medium is the water. In the case of sound waves, the medium that ...

Acoustic–gravity waves (AGWs) are naturally occurring sound waves that move through water at the speed of sound at relatively low frequencies. AGWs form with tsunamis and create pressure disturbances ...

The small device is encased in a special material that produces an electric signal every time it's hit by sound waves vibrating through the water. Those vibrations, in essence, vibrate it as well.

In the researchers' system, therefore, a transmitter sends sound waves through water towards a piezoelectric sensor. The acoustic signals, when they hit the device, ...
