Parametric loudspeakers use ultrasonic waves to create highly directional sound beams, allowing sound to be focused in a specific area without disturbing surrounding spaces. This technology exploits the non-linear interaction of ultrasonic waves in the air to demodulate audible sound, enabling applications in targeted audio delivery and noise pollution reduction.

Parametric Loudspeakers

Ultrasonic waves are sound waves with frequencies higher than the upper audible limit of human hearing, typically above 20 kHz, and are utilized in various applications such as medical imaging and industrial non-destructive testing. These waves can propagate through different media, allowing for their use in both diagnostic and therapeutic technologies.
