Hishico IP Broadcasting System and Professional Sound Reinforcement System Have Been Fully Commissioned, Setting a New Benchmark for Educational Soundscapes in Northwest China
• Today, as the digital revolution and educational modernization are deeply intertwined, the “auditory environment” on campus is no longer limited to simple class bells. It embodies the clarity of knowledge transmission, the warmth of cultural immersion, and the reliability of emergency command and control. With the completion of the final audio calibration, Yinchuan No. 41 Middle School marked a milestone in its campus acoustic infrastructure development—the Hishico IP network broadcasting system and the professional sound reinforcement system for the auditorium were successfully installed and put into operation. This modern school, situated in the “Jianan of the Frontier,” now possesses an “auditory hub” that combines an intelligent control system with a professional sound field.
I. From “A Single Cable” to “A Network”: How IP Broadcasting Systems Are Reshaping the Auditory Landscape of Campus Life
When you step onto the campus of Yinchuan No. 41 High School, you won’t hear the background electrical noise typical of traditional analog broadcasting, nor will you notice the jarring volume inconsistencies between different areas. Behind the scenes, Hishico fully digital IP network broadcasting system operates silently.
This system has completely overcome the physical limitations of traditional broadcasting, where a single amplifier served all areas. Leveraging the school’s existing gigabit campus network, it converts broadcast signals into digital IP packets, enabling a smart system characterized by “independent control across multiple zones and real-time responsiveness across all devices.”
• Precise zoning with no interference: Classroom buildings, playgrounds, cafeterias, dormitories, underground parking garages… The entire campus is divided into dozens of logical zones. During morning reading, classroom buildings play English listening exercises at a low volume; during recess, the playground area independently plays energetic exercise music; and at lunchtime, the cafeteria switches to soothing background music. Each area fulfills its specific function, truly achieving “a unique atmosphere in every room, with each zone distinct from the others.”
• Zero latency and high-definition sound quality: PCM lossless audio transmission technology ensures that audio latency from the control room to the farthest speakers is kept within the millisecond range, with a Speech-to-Interference (STI) index far exceeding national standards. Whether it’s a solemn speech under the national flag or a nuanced appreciation of classical music, every note is delivered with true-to-life fidelity.
• Visualized Cloud Control Platform: Staff on duty can view the online status of each terminal directly on the large screen in the monitoring room. In the event of an emergency, the system can trigger the “forced switch” function with a single click, forcing all zones to switch to emergency broadcast mode, thereby building an impenetrable “acoustic defense line” for campus safety.
II. Sound Field Reconstruction, Concert Hall-Quality Sound: The Art of Professional Sound Reinforcement in Lecture Halls
If IP broadcasting is the “arteries” of the campus, then the multi-purpose auditorium serves as the “acoustic heart” where the school engages with the outside world and where students and faculty showcase their talents. Taking into account the architectural acoustics of this auditorium, the Hishico technical team conducted a precise EASE sound field simulation and design, ultimately delivering a professional sound reinforcement system characterized by **high fidelity, wide dynamic range, and strong directivity**.
• Line Array Main Coverage, Uniform Sound Distribution: Hishico line array speakers are suspended on both sides of the main stage, paired with cardioid subwoofers. This setup ensures sufficient sound pressure levels for the rear audience while minimizing excessive wall reflections. Whether it’s the clarity of human voices during academic lectures or the grand dynamics of symphonic music in cultural performances, the system handles it all with ease.
• Monitor and Front-of-House Sound, Meticulous Attention to Detail: Dedicated monitor speakers are positioned at the front of the stage to ensure speakers and performers can hear their own voices in real time; front-of-house speakers effectively eliminate the “sound image void” effect for front-row audience members. Integrated with a digital audio processor, the system stores multiple preset scenarios—including “Lecture Mode,” “Performance Mode,” and “Movie Mode”—allowing for one-click switching and instant adaptation.
• Stability of the Wireless System: The auditorium is equipped with multi-channel UHF true-diversity wireless microphones. Combined with an antenna distribution system, this setup completely resolves the common issues of signal dropouts and frequency interference that occur when multiple microphones are used simultaneously during large-scale events. Faculty members remarked, “In the past, we were always worried about feedback and signal dropouts when using microphones. Now, no matter where we stand in the room, our voices sound as natural as if we were speaking right next to someone’s ear.”
III. Using Sound as a Medium to Shape the Future Together
Hishico has always firmly believed that the true value of educational equipment lies in its “unobtrusive presence” and “robust support.” The successful implementation of the project at Yinchuan No. 41 Middle School was not merely a matter of installing equipment; it was a deep integration of acoustic aesthetics with the educational environment.
• Exam Support: During the recently concluded end-of-term English listening exam, the IP broadcasting system ensured that hundreds of test-takers received clear and error-free audio thanks to its exceptional stability and resistance to interference, earning unanimous praise from parents and proctors alike.
• Cultural Hub: The auditorium has quickly become a cultural hub for the school. From lectures by renowned scholars to campus singing competitions, the clear, rich, and captivating sound ensures that every exchange of ideas resonates powerfully and that every young talent is showcased to perfection.
Conclusion:
From the first crisp wake-up call at the break of dawn to the melodious chorus echoing through the auditorium as the sun sets; from the patient and insightful classroom lectures in the academic buildings to the rousing athletic marches on the playground—Yinchuan No. 41 Middle School is writing a brand-new chapter in the “Smart Campus” initiative with the help of Hishico professional soundscape technology.
In the future, Hishico will continue to refine its products with a craftsman’s spirit, using audio technology to empower more educational institutions, so that the world can hear the wonderful echoes of Chinese campuses.
