Sound Absorption Effect to Suppress Excessive Sound Reverberation for Ease of Listening to TV Sound and Human Voices
Comparison of Reverberation Time Simulation Results (based on the sound absorption coefficient measurements on flooring)

When ceiling is finished with gypsum boards and vinyl cloth wallpaper
Reverberation time: Approx. 0.6 s/500 Hz (in 20-mat tatami room)
When ceiling is finished with CLEARTONE
Reverberation time: Approx. 0.6 s/500 Hz (in 20-mat tatami room)Pinhole-processed Surface for Enhanced Sound Absorption

Comparison of Formaldehyde Absorption Performance Test Results*1

- Environmental specifications for formaldehyde absorption test: Room temperature at 30℃, relative humidity at 50%, ventilation frequency 0.5 time/hour (in-house measurement), 6-mat tatami room, CLEARTONE 12S installation area rate 19%
- Installation area rate: Installation area of the CLEARTONE 12S ceiling material divided by the entire surface area of room (including openings)
- The measured test results in *1 are based on our laboratory measurement data and vary depending on installed furniture/interior equipment, temperature, airtightness, room size or plan, or other conditions.
