Factors contributing to echo issues inside the meeting room: The renovated meeting room has architectural features that are unfavorable for sound absorption.

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

Full-height glass on two walls which are reflective surfaces that trap and circulate sound within the room.

Vinyl tile flooring which, while easy to clean and durable, does not help absorb sound.

Large glass doors which act as pathways for sound to disperse back into the room.

These factors cause continuous "Echo" and "Reverberation," resulting in poor speech intelligibility during meetings, lack of vocal clarity, and long-term listening fatigue.

Solution from Trandar Acoustics

To enhance the acoustic quality inside the meeting room, the team chose Trandar Zivana Wall System 

• Trandar Heplar framing system (C74+U76) as the primary structure installed against the existing wall  
• Trandar dBPhon S50 fire-resistant, soundproofing, and thermal insulation
• Trandar ZIVANA sound-absorbing panels, 25 mm thickness

When installed together as a complete solution, it further enhances sound absorption performance.

Installing the sound absorption system on the solid wall areas significantly reduces reverberation time (Reverberation Time or RT60), ensuring clearer communication in meeting rooms.

Users experience greater comfort in speaking and listening, as well as improved focus during meetings.

Meeting spaces that fulfill both functional and acoustic requirements

Following the installation of the Trandar ZIVANA Wall System, spaces once filled with echoes have been transformed into quiet, noise-free meeting rooms perfectly suited to their intended purpose.
