The human ear detects sound. Sound waves enter the ear canal and cause the eardrum to vibrate. Three small bones transmit these vibrations to the cochlea. These bones transmit most efficiently ...

Experiments coupling light and sound reveal the surprising effect that measuring nothing can cool the vibrations of an object ...

The innovative sound display, which seamlessly translates auditory information into optical signals, addresses the challenges ...

In the future, this method could also be used in technical applications with electromagnetic waves. Water, light and sound waves usually propagate in the same way forward as in a backward direction.

Researchers at the University of Twente have solved a long-standing problem: trapping optically-generated sound waves in a ...

Thousands of marine species from microscopic zooplankton to the largest cetaceans rely on sound for survival and many have evolved unique oral and aural adaptations. Understanding them better could ...

So-called Rayleigh–Bloch waves can release enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency; above ...

Researchers at the University of Bayreuth have developed a method that makes objects on a magnetic field invisible within a ...

This particular snow was light and fluffy, a perfect sound absorber. When the ground is covered with fresh, dry, fluffy snow, sound waves are absorbed into all the air pockets in the snow ...

The process is very similar to ultrasound imaging, however the sound waves used are within normal hearing range, and they are used to identify objects rather than internal structures. This ...
