DSPPA | Directional Speaker for a School Playground in Shenzhen

Abstract: Our directional speakers deliver precise audio across the campus, enhancing educational efficiency and campus quality.

DSPPA Directional Sound Reinforcement System has been successfully applied to the Wuzhou Campus of Shenzhen Mingde Experimental School, ensuring precise sound distribution and control across the campus, and significantly enhancing the efficiency of educational activities and the overall quality of the campus environment.

Project Overview

Shenzhen Mingde Experimental School (Group) is a modern public school offering a 12-year integrated education program, encompassing elementary, middle, and high school levels, operating under a group-based model.

Surrounded on three sides by residential communities, this campus faces challenges in balancing the educational needs of the school with the residents’ quality of life, particularly in addressing noise concerns.

To effectively address this challenge, the campus has implemented the DSPPA directional sound reinforcement system, complemented by a dedicated DSP digital audio processor, allowing for precise parameter adjustments tailored to the specific environment and optimizing sound distribution.

By employing technologies like directional audio and localized sound control, the system ensures that broadcast audio is concentrated within the designated areas of the sports field, providing precise coverage while minimizing sound spillover into nearby residential areas.

As a result, the school can conduct various educational activities while significantly reducing sound interference in the surrounding neighborhoods, thereby enhancing the quality of life for both the campus and the community.
