In small to medium-sized meeting rooms, echo and speech intelligibility issues are common—especially in spaces with hard surfaces such as glass partitions, concrete walls, and suspended ceilings. This case study explains how a 30 square meter meeting room achieved clear, comfortable acoustics using polyester fiber acoustic panels, directly manufactured by our factory.
Project Background
Room size: 30㎡
Ceiling height: approx. 2.8 m
Main issues: strong echo, unclear speech during meetings, sound fatigue
Surface conditions: painted walls, glass window, tiled floor
Primary use: internal meetings, video calls, client discussions
The reverberation time (RT60) was estimated to exceed acceptable levels for a meeting room, resulting in overlapping voices and reduced communication efficiency.
Acoustic Solution Strategy
To address the problem, we adopted a targeted absorption approach rather than full-surface coverage, focusing on mid- and high-frequency sound control, which is critical for speech clarity.
Product Selection
Material: Polyester Fiber Acoustic Panels
Thickness: 9–12 mm
NRC: up to 0.85 (depending on panel thickness and installation method
Features:
Lightweight and easy to install
Made from recycled PET fiber
Non-toxic, formaldehyde-free
Durable and dimensionally stable
As a factory manufacturer, we adjusted panel size and color to match the room’s layout and interior design requirements.
Installation Layout
Wall coverage: approx. 40–50% of total wall area
Key positions:
Rear wall behind seating
Side walls at first reflection points
Partial coverage near the video conference screen
Panels were installed using adhesive mounting, allowing fast installation without structural modification.
Results After Installation
After the installation of polyester fiber acoustic panels:
Echo and flutter echo were significantly reduced
Speech clarity improved noticeably during meetings
Video calls became more natural with less microphone feedback
Overall acoustic comfort increased, reducing listening fatigue
The space now meets the practical acoustic requirements of a modern meeting room without sacrificing aesthetics.
Why Polyester Fiber Acoustic Panels?
Polyester fiber panels are an efficient and cost-effective solution for small and medium spaces. Compared with traditional materials, they offer:
Balanced acoustic performance for speech environments
Flexible design options (color, CNC cutting, patterns)
Easy logistics and lower installation cost
Consistent quality through factory-direct manufacturing
