Kingpower Corridor

“Why do high ceilings amplify ‘echoes’ so much? And how can you truly make them quieter?”

In large public spaces such as shopping malls or corridors, many people may unconsciously feel that “the sound is boomy” or “unclear,” especially in areas resembling airportswith high ceilings and numerous hard surfaces. The answer to this problem is “reverberation” bouncing back and forth within the space, and this was the challenge for the King Power Rangnam project.

The Origin of the Problem: A Corridor Where “Speech Is Unclear” Despite a Beautiful Look

The corridor area of the project is a primary walkway used by a large number of people. The space is characterized by:

• High ceilings
• Surrounding surfaces made of hard materials
• Sound reflections from multiple directions

This presents the exact same conditions as an “airport,” where echo and reverberation problems easily occur.

The resulting impacts are:

• Unclear speech intelligibility
• Accumulated noise within the space
• An unintentionally diminished user experience

The Solution Approach: Transforming the “Ceiling” Into an Acoustic Controller

Trandar stepped in to analyze and design a solution to resolve the reverberation issue in this corridor space.

By selecting the Trandar SeriesF acoustic ceiling,

which is designed to:

 👉 Absorb sound reflections from above

 👉 Reduce noise buildup in open spaces

 👉 Make overall sound “calmer and clearer”

Why Trandar SeriesF ?

Because in high-ceiling areas, the “ceiling” is the most acoustically influential point. Trandar SeriesF thus acts to transform the ceiling from a “sound-reflective surface” into a “sound-absorbing surface,” helping to reduce:

• Echoes
• Reflections
• Acoustic disturbance within the space

Results: The Same Space… But a Transformed Experience

After installing the acoustic system, the corridor area of King Power Rangnam has a markedly "quieter" atmosphere. Speech is clearer, background noise is reduced, and users experience better acoustic comfort in the space.

Because in crowded areas, sound quality is part of the experience.

And that is why King Power chose solutions from Trandar Acoustics.
