Using high-frequency sound waves to make tunable optical filters, modulators and Q-switches is a well-established and convenient technological solution for many applications, reports Neil Savage.

Audible enclaves are small pockets of sound that are not disturbed by surrounding noise. They are produced by new ...

modulated sounds waves. The transmitter and receiver For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into his laptop. That outputs both the audio ...

The height of each wave cycle is directly associated to the volume of the sound being measured or emitted ... good or useful plugin iterations of modulation effect are either modelled on, or ...

Memory Wave is built on advanced soundwave technology that stimulates gamma brainwaves -the specific frequency range linked to learning, memory retention, and heightened awareness. These are the brain ...

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM ...
