        "text": "Wall insulation contributes significantly to soundproofing by adding mass and density within wall cavities, which helps absorb sound waves. Denser materials like cellulose, mineral wool, and closed-cell spray foam are particularly effective at reducing airborne noise transmission between rooms or from outside. While its primary function is thermal resistance, insulation acts as an acoustic barrier, dampening vibrations and sound frequencies. This results in a quieter, more comfortable indoor environment, enhancing privacy and reducing external disturbances.",
