"Why do high halls become 'more reverberant'? And how can it truly be quieted?"

In large public areas such as shopping malls or corridors, many people might have unknowingly felt that "the sound is diffuse" or "unclear," especially in areas similar to airports with high ceilings and many hard surfaces. The answer to this problem is "reverberation" that reflects back and forth in the space. And this was the challenge for the project King Power Rangnam.

The Beginning of the Problem: A Corridor with "Unclear Sound" Despite its Aesthetic Appeal

The corridor area of the project is a main walkway with a large number of users. The characteristics of the area are:

• High ceilings
• Surrounding surfaces are hard materials
• Sound reflection from multiple directions

These are the same conditions as areas like "airports," where reverberation problems often occur easily.

The results are:

• Unclear speech
• Accumulated noise in the area
• Users' experience unknowingly decreases

Solution Approach: Transforming the "Ceiling" into a Sound Controller

Trandar stepped in to analyze and design a solution to solve the reverberation problem in this corridor area.

By choosing to use acoustic ceiling Trandar FocusF

which is designed to

👉 Absorb sound reflections from above

👉 Reduce sound buildup in open spaces

👉 Make the overall sound "calmer and clearer"

Why Trandar FocusF?

Because in areas with high ceilings, the "ceiling" is the most impactful point for sound. Trandar FocusF therefore transforms the ceiling from a "sound-reflecting surface" into a "sound-absorbing surface," helping to reduce:

• Reverberation (Echo)
• Reflection
• Sound chaos in the area

Result: Same Space…Different Experience

After installing the acoustic system, the corridor area of King Power Rangnam clearly has a "calmer" atmosphere. Speech is easier to understand, noise is reduced, and users can perceive the space better.

Because in areas with many people, sound quality is part of the experience.

And that's why King Power chose solutions from Trandar Acoustics.
