Application scenario: Education (educational space)
Core products: Standard PET Acoustic Panels (Wall-mounted & Grooved)

Project Context: A 300-seat university lecture hall with traditional drywall finishes.
The Challenge: Students at the back struggled to hear professors clearly due to sound reflection lagging from the rear walls.
The Solution: Installed CNC-grooved Qianqiao PET felt panels on the rear and side walls to absorb mid-to-high frequency reflections.
The Result: Speech Intelligibility (STI) increased from “Poor” to “Excellent”, ensuring a distraction-free learning environment.
