A team of researchers have developed "audible enclave" technology that creates pockets of sound that can be heard at a ...

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.

Electromagnetic waves are members of a family of waves with ... Analogue data must be converted to digital before a computer can use it. Sound can be transmitted as an analogue signal when you ...

Scientists have been unable to confirm the existence of time reflection due to the amount of energy required to create a temporal interface. Using an engineered metamaterial scientists in New York ...

Sound is a vibration that travels through air as a wave. These waves are created when an object moves back and forth, compressing and decompressing air molecules. The frequency of these vibrations ...
