5 Important Criteria to Consider When Choosing an Acoustic Felt Panel

1. Sound Absorption Coefficient (NRC Value)

The most fundamental task of an acoustic panel is to absorb sound. A panel's success in this is measured by its NRC (Noise Reduction Coefficient). NRC values range from 0 to 1, where 0 indicates the sound is fully reflected and 1 indicates it is fully absorbed. The acoustic felt panel you choose should have an NRC value of 0.70 or higher. High-density felts trap sound waves between their fibers and effectively reduce echo in the environment.

2. Material Density and Thickness

Panel performance is directly linked to material weight and thickness. Standard acoustic panels typically range between 9 mm and 12 mm thickness. However, thickness alone is not enough — density matters. Low-density panels are soft but have limited absorption. High-density felt panels made from PET or natural wool, even if thinner, are far more successful at absorbing mid- and high-frequency sounds.

3. Fire Resistance and Safety Certifications

Especially in crowded spaces such as offices, restaurants, and schools, decorative materials must comply with safety standards. When choosing an acoustic felt panel, look for international fire classifications such as B-s1, d0. These certifications indicate the panel is flame retardant, emits very little smoke, and produces no flaming droplets. This is non-negotiable for both legal compliance and human safety.

4. Environmental Impact and Sustainability

Today, decoration is not only about elegance but also about ethical responsibility. Question what raw material your panel is produced from. Felt panels made from recycled polyester (PET) fibers offer both excellent acoustic performance and environmental contribution. Producing each panel from recycled bottles is a small but meaningful step toward a greener planet. Also look for OEKO-TEX certification, ensuring no harmful substances.

5. Installation Ease and Design Flexibility

No matter how high the quality, if installation is difficult, application cost rises. The products you choose should be lightweight, applicable without damaging the existing wall structure (using adhesives or clip systems), and easy to cut and shape when needed. Design-wise, modular panels are always advantageous. Hexagon or stripe-shaped panels allowing different color combinations let you create your own wall art and add aesthetic value.
