Terahertz (THz) parametric oscillators are advanced devices that generate electromagnetic waves in the terahertz frequency range, which lies between microwave and infrared frequencies. These ...

These vibrations originate from the source and travel, ultimately, to your ear in the form of waves ... EQ, which has sliders for different frequencies. The other kind of EQ is a parametric ...

Parametric Array Loudspeakers (PALs): Loudspeakers that use ultrasonic waves to create audible sound through demodulation, allowing for highly directional sound projection. Demodulation ...
