Project Overview
To improve classroom communication and create a more comfortable learning environment, Wen'an No.1 High School in Hebei Province upgraded more than 100 classrooms with the Audfly Array Loudspeaker System.
The project aimed to provide balanced sound coverage, improve speech intelligibility, and reduce teacher vocal strain, helping create a more effective and comfortable classroom audio environment for both students and teachers.
The Challenge
As teaching requirements continued to evolve, the school's existing classroom audio systems were no longer able to provide consistent sound coverage throughout each classroom.
Common challenges included:
-
Uneven sound distribution between the front and rear seating areas
-
Reduced speech clarity for students seated farther from the teacher
-
Acoustic feedback caused by conventional amplification systems
-
Teachers needing to raise their voices during lessons, resulting in vocal fatigue
The school needed an audio solution that could improve classroom communication while delivering a more balanced listening experience.
The Solution
Audfly deployed its
Array Loudspeaker System across more than 100 classrooms, creating a consistent and balanced sound field throughout each teaching space.
Powered by SSADT (Spatial Sound Field Array Distribution Technology), the system distributes sound evenly across the listening area while reducing unnecessary reflections from ceilings and floors. Bluetooth connectivity also allows teachers to connect wirelessly, making daily classroom operation more convenient.
The upgraded system maintains a sound pressure level variation of no more than ±2 dB between the front and rear seating areas, ensuring that students throughout the classroom receive clear and consistent speech.
The Results
Following the installation, the school achieved a more balanced classroom sound environment across all teaching spaces.
Key benefits included:
-
Balanced sound coverage throughout the classroom
-
Improved speech intelligibility for all students
-
Sound pressure level variation maintained within ±2 dB
-
Reduced teacher vocal strain
-
Lower risk of acoustic feedback
-
More comfortable and engaging classroom experiences
The successful deployment across more than 100 classrooms demonstrates how a professionally designed classroom audio system can improve teaching effectiveness while creating a healthier listening environment.
