[Xi'an Yanta District No. 2 Middle School] Successfully Installs Hishico Audio-Visual Broadcasting System, Ushering in a New Chapter in Smart Education
In today’s world, where information technology and education are deeply integrated, Xi’an Yanta District No. 2 High School has once again taken the lead in innovation. Recently, the school fully implemented and successfully deployed Hishico next-generation intelligent audio broadcasting system, using technology to transform the campus acoustic environment and create a healthy, clear, and smart new learning experience for teachers and students. This initiative not only marks a new milestone in the school’s digital transformation but also embodies a modern educational philosophy centered on the development of teachers and students.
Analysis of the System's Highlights:
✔ High-fidelity sound quality that accurately reproduces real-life speech environments
The Hishico Hearing Assistance System utilizes advanced digital audio processing technology, with a frequency response range of 20 Hz to 20 kHz and a signal-to-noise ratio exceeding 90 dB, enabling it to perfectly reproduce every detail of the original English pronunciation. The system supports playback of various high-bitrate audio formats, such as MP3 and WAV, ensuring lossless audio quality for listening materials. Compared to traditional analog broadcast systems, the Hishico digital system delivers clearer and richer sound. In particular, it accurately reproduces pronunciation characteristics common in English—such as plosives and connected speech—helping students develop the ability to recognize authentic pronunciation.
✔ Dual-system redundancy design
Featuring an innovative “digital IP + analog backup” dual-architecture design, the system can seamlessly switch to a backup line within 50 ms upon detecting a network anomaly, ensuring zero disruption to listening instruction. The system supports real-time status monitoring and intelligent buffer compensation, with a reliability rate of 99.99%, providing military-grade assurance for English listening instruction.
✔ Stable and reliable, suitable for a variety of teaching scenarios
The Hishico Hearing Assistance System is built with industrial-grade hardware, offering excellent interference resistance and stability. The system supports both wired and wireless transmission modes, ensuring stable signal transmission even in complex electromagnetic environments. Each classroom is equipped with an independent volume control terminal, allowing teachers to adjust the volume as needed. The system also features a power-off memory function, which automatically restores the system to its pre-power-off state after an unexpected power outage, ensuring the continuity of instruction.
Practical Applications:
1. A Revolutionary Improvement in English Listening Classes: In traditional English listening instruction, teachers often face challenges such as complex equipment operation, poor sound quality, and inconsistent student comprehension. The introduction of the Hishico Listening Broadcast System has completely transformed this situation.
2. Perfect Simulation of a Standardized Testing Environment: As a school that prioritizes students’ all-around development, Yanta No. 2 High School organizes multiple English listening mock exams each year. The Hishico system’s precise synchronization ensures that listening playback begins and ends simultaneously in all testing rooms, eliminating incidents caused by cassette tape jams or CD skips that are common in traditional methods. The system also supports simultaneous playback of listening content for both Test Sets A and B, providing a reliable foundation for the school to organize large-scale standardized exams.
3. A New Platform for Promoting Campus Culture: The school can use this system to broadcast English news, recitations of classic literary works, and campus radio programs during breaks, fostering a rich atmosphere for language learning. The system supports zone-specific broadcasting, allowing different content to be played in different areas, thereby enabling precise information delivery.
Looking Ahead:
• The successful implementation of Hishico audio-broadcasting system at Xi’an Yanta District No. 2 High School has not only improved the school’s educational quality but also provided valuable insights for the digital infrastructure development of neighboring schools. In the process of educational modernization, this model—which empowers education through technology and drives development through innovation—is leading basic education toward a more intelligent and personalized future.
• We look forward to seeing more schools, with the support of outstanding edtech companies like Hishico, follow in the footsteps of Yanta No. 2 Middle School by leveraging technological innovation to create a better educational experience for teachers and students, and together write a new chapter in the modernization of China’s education system.
