Ears, on the other hand, act more like microphones, capturing sound through vibrations in the air. When someone speaks, sound waves hit the eardrums, vibrating and sending signals to the brain.

A new tool that assesses the level of danger posed by tsunamis in real-time has been made operational on a global scale.

A stellar concert is playing out in the night sky, and scientists are learning how to listen to it like never before. Deep ...

Mysterious radio signals detected emanating from Antarctica's ice have left particle physicists baffled. The pulses were ...

Sound waves can also steer objects inside organisms. Daniel Ahmed, an engineer at ETH Zurich in Switzerland, ... Thus, the device can distinguish a transmission signal from a return signal, ...

Sound waves can reflect off surfaces. We hear reflected sound as an echo. Hard, smooth surfaces are particularly good at reflecting sound. This is why large, empty rooms produce lots of echoes.

The researchers explain that as the sound waves travel in one direction, they naturally enable non-reciprocal behaviour for the optoacoustic interaction. In this way, OAM modes can be either strongly ...

Sound waves and sea creatures. ... Besides these love songs, toadfish also use acoustic signals to ward off competitors, socialize and establish territory.
