Background:
The campus broadcasting system, serving as core infrastructure for daily school management, teaching activities, and cultural dissemination, has long faced technical challenges in sound propagation control. Traditional systems rely on omnidirectional sound projection, causing undifferentiated sound wave dispersion and severe sound spillover issues. In playground scenarios, broadcast sound waves often extend beyond campus boundaries, creating persistent disturbances for surrounding communities. According to legal advisory data on noise pollution, school broadcast disturbances have become a primary source of urban noise complaints, particularly during morning exercises, breaks, and sports events, significantly impacting nearby residents.

Solution Overview:
The Quiet Playground Outdoor High-Power Directional Audio System - L200 Solution is an integrated directional acoustic system. Leveraging our proprietary controlled sound field technology, it concentrates sound energy within designated directions and spatial boundaries. This ensures clear and immersive audio within school grounds while instantly reducing external noise pollution. Compared to traditional systems, the L200 effectively confines sound within a 30-degree angular range in front of the device, beyond which volume rapidly attenuates to levels below environmental standards (typically under 55 dB).

Features:

• Highly Directional Sound: Precise directional audio propagation prevents public disturbance.

• Eco-Efficient Audio: Delivers clear sound within the main sound field with minimal distortion.

• Multi-Channel Synchronization: Enables coordinated multi-device operation without interference, featuring broadcast-grade system control.

• Weather-Resistant Design: Protects against rain, mold, sunlight, and corrosion, adapting to diverse natural environments.

• Easy Installation & Low Maintenance: Simple deployment, cost-effective upkeep, and effortless disassembly for adjustments.
