Project Overview
Located in a densely populated urban area, Jinxing Middle School in Wuxi, China, has a playground adjacent to residential buildings. Daily activities such as morning exercises, assemblies, and outdoor events require clear public address coverage, but conventional loudspeakers caused excessive sound to spread beyond the playground, resulting in noise concerns from nearby residents.
To improve speech clarity across the playground while minimizing noise impact on the surrounding community, the school upgraded its outdoor audio system with the Audfly
Outdoor Directional Speaker System.
The Challenge
Traditional outdoor loudspeaker systems broadcast sound in all directions, making it difficult to provide adequate coverage across the playground without increasing noise beyond the playground boundary.
The school faced several challenges:
-
Sound easily spread into nearby residential areas.
-
Higher volume levels were required to reach students at the far end of the playground.
-
Students close to the speakers experienced excessive sound levels, while those farther away struggled to hear announcements clearly.
-
The school needed to balance effective campus communication with community noise control.
The Solution
Audfly deployed its Outdoor Directional Speaker System to create a more controlled sound field across the playground.
Using directional audio technology and advanced sound field control algorithms, the system projects sound toward the listening area while significantly reducing sound propagation behind the speakers.
The customized installation was designed according to the playground layout and surrounding buildings, ensuring uniform sound coverage across the playground during school activities while significantly reducing sound spillover beyond the playground boundary.
The Results
Following the upgrade, Jinxing Middle School achieved clearer and more consistent sound coverage with significantly improved noise control.
Students across the playground could hear announcements more clearly, while surrounding residents experienced noticeably less noise during school activities.
Key benefits included:
-
Reduced sound spillover beyond the playground boundary
-
More uniform sound coverage across the playground
-
Improved speech intelligibility for announcements
-
Reduced noise impact on nearby residential areas
-
Better balance between campus communication and community comfort
The project demonstrates how directional audio technology can help schools create effective outdoor communication systems while maintaining a quieter environment for surrounding neighborhoods.

Conclusion
Schools, universities, sports facilities, and other outdoor venues often face the challenge of delivering clear audio without disturbing nearby communities.
Audfly's Outdoor Directional Speaker System provides a practical solution by focusing sound where it is needed while reducing unwanted noise outside the target area, helping schools improve communication while maintaining a quieter environment for nearby communities.
