Written by Bernard D. Beitman M.D. and Ruslana Remennikova, MS. Since the beginning of human civilization, history has shown a correlation between sound and cognitive, mental, and physical wellness. 1 ...

Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

In recent years, there has been a lot of interest in coupling sound and light together. Admittedly, we’ve been doing this for a long time, but we’ve always been limited in terms of what we can do with ...

(Nanowerk News) An international team of researchers showed how a nonlinear elastic metasurface could convert a wave’s fundamental frequency to its second harmonic. Structural factors in metasurfaces, ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

The most important mechanical wave to our everyday lives is sound. So how exactly do we hear? What is the definition of sound? The Definition of Sound The first thing we should understand about sound ...

Hey all! So all my life I have heard that sound is a type of wave. This seemed to make sense to me. Recently I have come across some information that has me second guessing such tradition knowledge.

A hearing sensation arises when the elastic basilar membrane inside the cochlea vibrates. The basilar membrane is typically set into motion through airborne sound that displaces the middle ear and ...
