Looking up at the night sky, it may seem our cosmic neighborhood is packed full of planets, stars and galaxies. But ...

Sound waves are produced by movement. Animals have evolved organs to detect those sound waves in the air or water to perceive ...

This breakthrough sound wave director consists of a disk-shaped cavity with three equidistant ports for sending or receiving sound. When activated, sound from one port is only heard at a specific ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.

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 refers to sound waves with frequencies above the human hearing range, or above 20 kHz. These waves travel through the air like normal sound waves but are inaudible to people.
