D acoustic panels are sound-absorbing wall elements with a sculpted or textured surface that adds depth, style, and functionality to interior spaces. These panels are crafted with three-dimensional designs, such as geometric patterns, wave shapes, or custom textures, to enhance sound absorption by disrupting sound waves more effectively than flat surfaces. Typically made from materials like polyester, PET felt, wood, or foam, they help reduce echoes and manage reverberation, creating a quieter and more comfortable environment.
