Hefei No. 48 Middle School introduced an advanced classroom audio solution designed to improve the listening experience for both teachers and students.
As Anhui Province's first demonstration site for a healthy school acoustic environment, the campus adopted Audfly's Array Loudspeaker System alongside an AI-powered hands-free voice amplification solution to address common classroom audio challenges, including uneven sound distribution, teacher voice strain, and background noise interference.
The solution enables teachers to speak naturally and move freely around the teaching area without holding or wearing a microphone, while providing clear and consistent audio coverage throughout the classroom.
Traditional classroom amplification systems often struggle to provide an even and comfortable listening experience.
Students in the front rows may experience excessive volume, while those at the back struggle to hear clearly.
Teachers often need to raise their voices to reach students at the back of the classroom, increasing vocal fatigue over time.
Handheld and wearable microphones can restrict teachers' movement and classroom interaction.
Sounds from air conditioning, keyboards, and page turning may be amplified along with the teacher's voice, affecting speech clarity.
The school needed a solution that could deliver balanced sound coverage, reduce background noise, and allow teachers to teach naturally without being restricted by microphone equipment.
Audfly provided a customized classroom audio solution for Hefei No. 48 Middle School, centered on its Array Loudspeaker System and complemented by directional voice pickup and AI noise reduction technologies.
The Array Loudspeaker System uses Audfly's proprietary Spatial Sound Field Array Distribution Technology (SSADT), combined with professional acoustic algorithms and multi-channel DSP audio processing, to create a more balanced sound field throughout the classroom.
Volume difference between the front and back of the classroom
This helps students hear the teacher clearly regardless of their seating position.
To support hands-free teaching, the solution incorporates a directional voice pickup microphone with AI-based noise reduction technology.
Together, these technologies help deliver clearer speech without requiring teachers to hold or wear a microphone.
Teachers can move freely around the teaching area and speak naturally at a normal volume, without the need for handheld or wearable microphones.
The solution is designed for straightforward installation and commissioning, minimizing modifications to existing classroom facilities and helping reduce disruption to daily teaching activities.
Following installation, the classroom audio solution improved the listening experience for both teachers and students.
Balanced sound coverage helps students hear clearly from different seating positions.
Teachers can deliver lessons at a natural speaking volume without constantly raising their voices.
The hands-free design allows teachers to move naturally and interact more freely with students.
Directional voice pickup and AI noise reduction help minimize background noise interference.
The project established Anhui Province's first demonstration site for a healthy school acoustic environment, providing a practical reference for improving classroom sound environments in other schools.
Whether you need balanced sound distribution throughout a classroom or targeted audio delivery in designated areas to minimize sound spill into surrounding spaces, Audfly offers tailored acoustic solutions for different environments and applications.
