AI Acoustic Defense & Precision Dispersion - LRAS1515AI Intelligent Acoustic Hailing System Solution with AI Automatic Feedback Suppression

I. Solution Overview

● With the acceleration of urbanization, issues related to public safety, environmental protection, and urban management have become increasingly prominent. In particular, in sensitive areas such as industrial zones, military facilities, highways, and urban squares, there is often a need to disperse or evacuate people through special means. Traditional approaches, such as manual dispersal and police enforcement, are inefficient, costly, and slow to respond, making it difficult to accomplish the task quickly and effectively. As a result, high-intensity sound dispersal systems based on high-frequency acoustic waves have emerged as an innovative and viable solution.

Requirement Analysis

● Distance Limitation: Conventional speakers have a limited brocast range, making it difficult to hear clearly at a distance.

● Environmental Interference: In high-noise environments, such as storms, crowd noise, or machinery roar, voice intelligibility is insufficient.

● Poor Directivity: Sound spreads diffusely, preventing precise directional transmission and potentially causing disturbance or information leakage.

● Slow Deployment: Complex system setup and inconvenient power supply make rapid deployment under emergency conditions difficult.

II. LRAS1515AI Application Solution

The LRAS1515AI Acoustic Hailing System is a portable, multifunctional device that integrates high sound pressure and strong directivity for long-range acoustic command and dispersal. The system consists of the LRAS1515PII Acoustic Hailing Player, the LRAS1515S Active Long-Range Directional Acoustic Hailing Speaker, and the LRAS1515M Handheld Microphone. It is suitable for a variety of scenarios, including long-distance voice broadcasting, warning alerts, emergency command, and crowd dispersal.
