Flutter Echo on Parallel Wall Surfaces
Parallel reflective walls can cause disturbing flutter echo and repeated reflections that weaken the clarity of discussion.

Conference Hall Acoustic Design & Solution
High-performance conference hall acoustic design focuses on maximizing speech intelligibility. Echo, noise interference and unclear voice transmission will reduce communication efficiency during meetings. Our acoustic material solutions eliminate common acoustic defects for formal meeting spaces.

Key Acoustic Challenges
Common Acoustic Defects of Meeting Spaces
Poor Speech Intelligibility in Large Conference Rooms
Long reverberation, background noise and video-conference reflections make speeches harder to understand across larger rooms.
- Disturbing echo and flutter echo between parallel walls
- Long reverberation making speeches hard to understand
- Background noise and sound reflection interfering remote video conference audio
- Noise spread to adjacent offices and corridors

Our Acoustic Solutions
Targeted Acoustic Improvement Strategies
We configure wall and ceiling sound-absorbing materials targeted for speech-based spaces. Our acoustic panels absorb reflected sound waves, shorten reverberation time and avoid repeated reflection.
Reasonable Layout of Wall & Ceiling Absorbers
The design supports both small multi-functional meeting rooms and large formal conference halls through coordinated rear-wall, side-wall and ceiling treatment.

Core Design Recommendations
Key Standards for Speech-focused Acoustic Environment
Controllable Reverberation Time Reference
Control the reverberation target against room volume, audience density, presentation format and conferencing equipment.
- Maintain reverberation time below 1.2 seconds
- Lay sound-absorbing panels on rear walls and partial side walls
- Avoid full hard, reflective wall surfaces
- Add ceiling absorption to suppress overhead sound reflection
