Ultrasonic Parametric Speakers by Audfly: Precision Sound

In an era where controlling sound is as critical as producing it, ultrasonic parametric speakers have emerged as the ultimate solution for delivering targeted audio. With patented innovations and a focus on real-world applications, Audfly leads the market in providing highly directional sound technology that redefines the possibilities of precision sound delivery.

1. Introduction: Redefining Precision Audio

Modern environments—from bustling airports to immersive museum exhibits—demand audio systems that can reach specific listeners without disturbing those nearby. Traditional loudspeakers scatter sound in all directions, making privacy, clarity, and efficiency a challenge. Ultrasonic parametric speakers solve this by focusing sound into a narrow beam, allowing audio to be directed with the precision of light. This technology is not only about sound—it’s about controlling the listening experience.

2. Understanding Ultrasonic Parametric Speaker Technology

At the heart of ultrasonic parametric speakers is the principle of modulated ultrasonic carriers. Audio signals are encoded onto ultrasonic waves (beyond human hearing), which travel in a narrow beam. When these waves interact with air molecules, they demodulate into audible sound precisely at the target area. This means people outside the beam hear little to nothing.

Directivity: Beam angles narrower than 15°, ideal for isolating sound zones.
Frequency Range: Enhanced low-frequency performance (down to 500Hz) for fuller sound.
Audio Isolation: Up to 10× better isolation compared to conventional speakers.

3. Key Advantages of Precision Sound Delivery

Ultrasonic parametric speakers are not just about innovation—they offer measurable benefits:

Deliver sound exactly where it’s needed.
Improve speech intelligibility in noisy spaces.
Protect privacy in environments like banks or hospitals.
Enhance immersive experiences in art and exhibitions.
Reduce noise pollution in public or shared spaces.

4. Applications Across Industries

The versatility of Audfly’s ultrasonic parametric speakers allows them to excel in diverse environments:

Museums & Galleries: Provide independent audio commentary for each exhibition area, without interfering with each other or disturbing visitors in other areas.
Retail & Advertising: Deliver targeted promotional messages to specific areas.
Transportation Hubs: Announce information to selected gates or terminals.
Corporate & Offices: Broadcast meeting reminders or security alerts to a defined zone.
Events & Exhibitions: Create focused, immersive audio for interactive installations.
