A New Way to Control Sound

Traditional insulation depends on mass, but acoustic metamaterials reshape how sound behaves. Their internal cavities create viscous and thermal interactions that convert sound into heat, while resonant spaces generate inverse waves that cancel incoming noise through controlled interference. Through these integrated mechanisms, our ultra-thin and tunable metamaterials deliver superior sound insulation across diverse applications.

Meta Panel: High-Impact Sound Control at Only 1 cm

Meta Panel redefines what thin acoustic solutions can achieve:

• 28 dB sound absorption performance
• 50–10,000 Hz wide frequency range
• Only 1 cm thickness
• Performance determined by engineered geometry, not material
• Ideal for space-restricted and weight-sensitive applications

MetaBack: High-Performance Acoustic Enhancement with Only 1 cm Added Thickness

MetaBack dramatically elevates standard passive materials by integrating our metamaterial architecture (mQWM):

• Adds only 1 cm additional thickness
• Achieves up to 90% sound absorption
• Provides 25 dB superior sound insulation at low and mid frequencies
• Works with existing passive materials and industrial processes
• Enables space-efficient, high-performance acoustic designs

Meta Bricket: Compact, Frequency-Targeted Acoustic Engineering

Meta Bricket delivers tunable performance with complete geometric freedom:

Tuning Capabilities

• Target frequencies adjusted by unit height
• Performance shaped by unit width without shifting tuning
• Width changes allow transformation from bar-like to plate-like forms
• Adaptable across industries: white goods, architectural acoustics, automotive, aerospace

Performance Advantages

• Conventional absorbers require much larger characteristic lengths:
  • 358 mm at 239 Hz
  • 327 mm at 262 Hz
  • 321 mm at 267 Hz
• Meta Bricket achieves similar results at one-sixth the thickness

Model Options

• 8 standard models (M1–M8)
• 4 special models (S1–S4)
• Models can be combined for wide frequency coverage

Acoustic Benefits

• Impedance-matched architecture reduces reflection
• Allows deep penetration of randomly incident sound waves
• Significantly enhanced low-frequency absorption
• Can pair with passive materials for broader broadband performance
