Soundproof drywall (like QuietRock) features a damping layer between gypsum panels that converts sound energy into heat. A single layer can match the sound reduction of multiple layers of standard drywall. In 2026, soundproof drywall prices average $50.00 per sheet (4x8), with a typical range of $35.00 to $70.00 depending on your region, supplier relationships, and order quantity.
