Simple Sound Processor presented here is an ultra-simple circuit module suitable for almost all basic electronics and microcontroller projects. For example, this module can be used as a front-end in ...

Sound is the vibrations of an object. It is transmitted in the form of waves with alternate increase and decrease in pressure. A vibrating object compresses the surrounding air molecules making them ...

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

Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

For more than 50 years, scientists have theorized that a special kind of reflection known as time reflections have existed in the realm of quantum mechanics. However, proving the existence of this ...
