Overview
Located in the center of Beijing, Ritan High School shares its campus boundary with nearby residential communities. Daily outdoor activities such as PE classes, morning exercises, and public announcements are essential to school life, but conventional loudspeaker systems often caused sound to spread beyond the playground, affecting nearby residents.
To address this long-standing challenge without limiting normal school activities, the school introduced the
Audfly Outdoor Directional Speaker system, creating a quieter acoustic environment for both the campus and the surrounding neighborhood.
A Smarter Outdoor Audio Solution
Instead of broadcasting sound in every direction, the Audfly Outdoor Directional Speaker system concentrates audio within the playground using advanced directional sound technology, localized sound field control, and Audfly's proprietary A-AFC algorithm.
The system delivers clear and balanced audio throughout the activity area while significantly reducing sound behind and beside the speakers. Its adjustable sound projection angles and cloud-based remote management also allow schools to optimize coverage for different activities without changing existing playground layouts.
Results
After installation, teachers reported clearer announcements and improved speech intelligibility across the playground. At the same time, sound reaching nearby residential buildings was dramatically reduced, helping minimize community noise complaints while maintaining a lively learning environment.
Field measurements showed that noise levels at the playground boundary decreased significantly compared with a traditional outdoor PA system, reducing sound impact on surrounding neighborhoods by approximately 70–80%.
Why Audfly Outdoor Directional Speakers
Audfly Outdoor Directional Speakers are designed for schools that require powerful outdoor communication without creating unnecessary noise pollution. By delivering precise sound coverage where it is needed, the system helps schools maintain effective outdoor teaching, sports activities, and emergency broadcasting while promoting a quieter and more harmonious relationship with surrounding communities.
