Factors contributing to echo problems in the meeting room: The renovated meeting room has architectural characteristics that are not conducive to sound absorption. 

• Low ceiling of only 2.50 meters which causes sound waves to reflect back to the speaker quickly.

• Two walls are full-height glass which is a sound-reflective material that causes sound to reverberate within the room.

• Rubber tile flooring which, despite being easy to clean and durable, does not absorb sound.

• Large glass doors which become a pathway for sound to spread back into the room.

These factors continuously create “Echo” and “Reverberation,” resulting in unclear listening in the meeting room, indistinct speech, and long-term auditory fatigue.

Solution from Trandar Acoustics

To enhance the sound quality within the meeting room, the team chose Trandar Zivana Wall System 

• trandar Heplar framework (C74 U76) as the main structure installed onto the existing wall.  
• Trandar dBPhon S50 fireproof, soundproof, heat-insulating insulation
• TranadarZIVANA sound-absorbing panel, 25 mm thick.

When all components are installed together as a solution, the sound absorption efficiency will be further improved.

The installation of the sound absorption system on the solid walls of the room significantly reduces the reverberation time (RT60), making communication clearer in the meeting room. Users feel more comfortable speaking, listening, and concentrating during meetings.

Meeting space that meets both functional and acoustic needs

After installing the Trandar ZIVANA Wall System, the area once filled with echoes was transformed into a "quiet, noise-free" meeting room suitable for its primary purpose.
