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.

Sound is all around us but do you know what is sound. It is a type of energy made up by the vibrations produced. It travels as a wave through a medium like liquid, solid or gas but it does not exist ...

Realistic sound rendering can directly impact the perceived realism of users of interactive media applications. An accurate acoustic response for a virtual environment is attuned according to the ...
