當藝術的吸音超乎預期──我們 Cymbals 系列的驚人表現

What happens when sculptural form meets serious acoustic function? We built the Cymbals Series to diffuse sound like an art installation. But when we ran a test, the results surprised even us.

With no tricks and just a calibrated mic and REW software, this sculpted 2" panel showed NRC values exceeding 2.0 in higher frequencies — numbers rarely seen outside of ultra-thick treatments or multi-layer setups.

What Was Tested

Panel: Cymbals Pro 2'x2' (50mm panel, no air gap, wall mount)

Test setup:

• Mic: UMIK-1 (calibrated), 90 degree calibration file (mic pointing upwards)
• Speaker: KEF Q350 (frequency response 50hz- 25000hz)
• Amplifier ICEpower 100AS2
  
• Software: REW (Room EQ Wizard)
• Room size: 19.61 square meter, 55.54 cubic meter
• Mic positions: 4 locations, 5 test at each location averaged
• Number of Panels: 6, 595mm x 595mm panels
• Hanging Method: no air gap
  

Note: This is in-room data, not ASTM-certified. Still, it tracks closely with our calibrated Surge panel lab results.

Why These Results Make Sense

The absorption spike from 200 Hz upward comes from three things:

1. Diffraction & Diffusion: The curved surfaces bend sound, scattering highs while creating micro-traps for mids.
   
2. Edge Effects: Sound wraps around the circular forms, increasing interaction surface area.
   
3. Air Gap Geometry: The angled mount creates deeper resonant cavities behind the panel — acting almost like a shallow Helmholtz system for midrange.
   

Where It Doesn’t Work (and Why That’s Fine)

Despite wild performance in the mids and highs, absorption below 200 Hz is near zero — as expected. That’s not a flaw. Most panels this size and depth can’t handle deep bass. That’s why we recommend pairing Cymbals with modular bass traps if you're treating a full-spectrum room.

See for Yourself

We’ve made the raw REW data available for download. If you're an engineer, audiophile, or just curious — dig into the waterfall charts, spectrograms, and decay curves.

Form and function don’t have to fight. With the Cymbals Series, we got both — more than we expected.
