“What causes echo in a meeting room?”
Ever experienced this…? You're in a meeting, and the speaker's voice keeps echoing, making it impossible to understand.
Even though the room looks beautiful and modern, it surprisingly “echoes”.
In reality, echo is caused by what is called Sound Reflection which is when sound reflects back from the floor, walls, or ceiling.
Especially in rooms with hard and smooth materials like glass, concrete, or metal, sound travels back and forth without any material to absorb it.
When sound reflections accumulate, it creates what is called
🌀 Reverberation Time (RT60) — or “the time sound lingers in a room after speech stops.”
If the RT60 is too long, the sound will overlap, be unclear, and make communication tiring.
🎯 So how can this problem be solved?
The answer lies in “controlling sound reflections.”
by using sound-absorbing materials (Acoustic Material) in appropriate positions.
such as ceilings, back walls, or points with the most sound reflection.
Materials like Trandar AMF acoustic ceilings or ZIVANA and many other sound-absorbing materials
which Trandar has researched and developed specifically to address sound problems.
This helps reduce RT60 to be suitable for conversation, making every word “clear” and “comfortable to listen to” even in a modernly designed meeting room.
💡 Trandar's solution — for meeting rooms with clear sound and beautiful aesthetics from every angle.
Because good sound…starts with materials that truly understand “sound.”
