Silencing Cities with Smart Material Solutions
With 90% of urban populations exposed to harmful noise levels (WHO), polyester felt is emerging as the cornerstone of acoustic architecture. Tokyo’s 2040 Silent City Initiative deploys felt-based systems to reduce ambient noise by 20dB(A).

Engineering Excellence

• Acoustic Performance:
  • NRC 0.95 rating for broadband absorption
  • Micro-perforated panels targeting 250-4000Hz traffic noise
• Durability:
  • UV-resistant for 25+ year outdoor use (ISO 4892-3)
  • Fireproof to EN 13501-1 Class A2

Case Study: NYC Subway Noise Mitigation
MTA’s $600M Quiet Subways Program uses:

• 50mm thick felt panels along tunnel walls
• Vibration-isolating rail pads (600gsm density)
• Self-cleaning hydrophobic coatings
  Result: 15dB(A) reduction in passenger cabin noise.

Economic & Environmental Impact

• $3.50 ROI per $1 invested in noise control (World Bank)
• 100% recycled content meets LEED v4.1 criteria
• 80% lower embodied carbon vs mineral wool

Regulatory Momentum

• EU Environmental Noise Directive 2024 revisions
• California’s AB 2968 Urban Noise Abatement Act
• China’s GB 3096-2022 acoustic standards

Future Innovations

• IoT-enabled panels adjusting porosity in real-time
• Photocatalytic felt degrading air pollutants
• Energy-harvesting strips from sound vibrations
•
