_x000D_ Additionally, Acousta-Blue boasts a Noise Reduction Coefficient (NRC) rating that is 30% better than fiberglass in thicknesses less than 3". This means it provides superior sound absorption, effectively reducing echoes within the speaker cabinet. The graph below shows the NRC for Acousta-Blue 30 mm (1.18") vs 50 mm (1.97"). _x000D_

_x000D_ Environmentally Friendly _x000D_

_x000D_ Acousta-Blue stands apart from other damping materials due to its exceptional features and eco-friendly nature. One key factor is its use of recycled denim, making it a sustainable choice that prevents denim from ending up in landfills. Not only does this contribute to environmental preservation, but the recycling process also enhances the material's resistance to flames, rodents, insects, fungi, and mildew. Unlike other traditional damping materials like foam which has similar NRC, Acousta-Blue does not dry out over time, ensuring long-lasting and consistent results. By choosing Acousta-Blue, you not only benefit from better damping and durability but also create a healthier indoor environment. _x000D_
