        "text": "Standard hollow-core interior doors have virtually no acoustic stopping power and undermine any sound-control work on the adjacent wall. A typical hollow door has a low sound transmission class, and sound freely passes through the gap beneath it. Replacing it with a solid-core wood or composite door adds significant mass. Additionally, installing perimeter acoustic jamb gaskets and an automatic drop-seal at the threshold creates an airtight perimeter when closed. A decision factor when planning a wall upgrade is recognizing that if you invest in double-stud or decoupled walls, retaining a standard hollow door will leave a direct leak that negates your investment.",
